R1-01-consumer-market-us-status.md - Answers to the core availability questions
Can new DJI models get FCC authorization? No. DJI and Autel are excluded from the exemptions and from the Conditional Approval path. Everything launched after Dec 22, 2025 is blocked in the US: Lito 1/X1, Osmo 360 II, SDR Transmission 2, and per DJI all its products including Osmo and Ronin gear.
R1-01-consumer-market-us-status.md - Answers to the core availability questions
Are existing drones legal to fly? Yes. The FCC says the action "does not affect any previously-purchased drone." Previously authorized models can still be legally imported and sold for now. The Aug 2026 proposal would end sales of listed models but not their use.
R1-01-consumer-market-us-status.md - Answers to the core availability questions
Retail reality in 2026. DJI's US site does not sell Mini 5 Pro or Mavic 4 Pro. Grey-market and third-party stock is available at Amazon, B&H, Adorama and Drone Nerds, often with non-US warranty. Examples: Mini 5 Pro $683–759 on Amazon (Mar–Jul 2026); Mavic 4 Pro ~$2,700. DJI stock ran dry in June 2025 and returned through Amazon third-party sellers in late Oct 2025. DJI expects to lose more than $1.5B in 2026.

Not drones / not released: Osmo 360 II (Sept 3, 2026) and Osmo Pocket 4 are cameras — there is no Osmo-branded drone. Air 4 and Avata 3 appeared in certification filings but were not released; Mini 6 and Mavic 5 are 2027 rumors. Matrice 5 is enterprise (prototype leaked Jul 2026). Ryze Tello was discontinued in late Dec 2023 when DJI exited education.

The only 2025 consumer launch that reached US shelves normally was the Antigravity A1 (Dec 4, 2025).
R1-01-consumer-market-us-status.md - Market notes
No US or allied brand has launched a mass-market consumer camera drone. One industry estimate put US-made consumer drones at ~$4,000–5,000 vs ~$759 for imports (Yahoo Tech, Aug 10, 2026) [UNVERIFIED].

Russia pioneered them at scale in the Kursk operation (Aug 2024–Mar 2025), with reported ranges of 30–40 km; Ukraine had approved 80+ domestic models by mid-2025. NATO made countering them the theme of its 2025 Innovation Challenge. They have spread to Sudanese militias and Mexican cartels (Atlantic Council, 2025).

R1-03-military-overview.md - 8. Civil–military crossover
Hobby technology in war: Ukraine's FPV strike drones grew out of racing-quad components — open-source flight software, Chinese motors, cameras and batteries. In H1 2024 about 89% of Ukraine's drone-related imports by value came from China, down from 97% (Snake Island Institute via FDD 2025-10-10). Ukraine and Orqa are pushing "China-free" builds, but mass production to that standard is years away (DroneXL 2026-03-11).
R1-03-military-overview.md - 8. Civil–military crossover

R1-03-military-overview.md - 8. Civil–military crossover
Effect on hobby supply and prices: FPV forums reported shortages of motors, frames, video systems and radios as early as 2023 (Digital Camera World 2023-04-02). Chinese export controls and the FCC Covered List add further pressure on non-Chinese, FCC-authorized hobby gear. Agricultural-drone prices doubled in Myanmar (ACLED). Ukraine reported fiber-optic spool shortages (Oboronka). [No systematic price data for the Western hobby market was found — treat as anecdotal]

(fcc.gov/supplychain/coveredlist)
R1-04-regulations-2025-2026.md - 2. United States: FCC Covered List (foreign-made drones)
Effect: no new equipment authorizations for covered devices, so new models cannot legally be imported or marketed. Existing devices [OFFICIAL, FCC FAQ]: the action "does not affect any previously-purchased drone" and does not bar import, sale or use of already-authorized models. The risk is that the FCC retains power to revoke existing authorizations. On 2026-07-06 (DA 26-635, effective 2026-07-16) it banned import and marketing of previously authorized equipment for items added to the Covered List on or before 2024-12-31 — a precedent, though R3-01 later confirmed it does not reach the Dec 2025 drone entries.

R1-04-regulations-2025-2026.md - 3. EU / EASA
The transitional period ended 2024-01-01. From then, new drones need a class mark to use the full Open subcategories, and "legacy" drones without a class mark are limited to A1 if under 250 g, otherwise A3 (up to 25 kg).
R1-04-regulations-2025-2026.md - 3. EU / EASA
Class marks: C0 (under 250 g) and C1 (under 900 g or under 80 J) → A1; C2 (under 4 kg) → A2; C3 and C4 (under 25 kg) → A3; C5 and C6 → Specific-category standard scenarios (added by Regulation 2020/1058).
R1-04-regulations-2025-2026.md - 3. EU / EASA
Direct Remote ID has been mandatory for C1, C2, C3, C5 and C6 drones since 2024-01-01. Specific-category operators must also broadcast it. Privately built drones must be registered if they weigh 250 g or more or carry a camera.
R1-04-regulations-2025-2026.md - 3. EU / EASA
2025–2026: no major amendment to the Open category was found. EASA published revised Easy Access Rules for UAS in June 2026 (contents unverified). CEN published EN 4709-001:2026, the test standard for C0–C4 compliance (round 1 estimated ~July 2026; R3-01 later dated it April 2026).

R1-04-regulations-2025-2026.md - 6. Other countries (brief)
Australia (CASA): drones over 250 g flown for fun must be registered, and pilots need free online accreditation; commercial work needs a RePL/ReOC, or the "excluded category" for drones under 2 kg with registration and accreditation. No major 2025–2026 rule change could be confirmed on a CASA page [UNVERIFIED at round 1; R4-03 confirmed no change].
R1-04-regulations-2025-2026.md - 6. Other countries (brief)
Japan (MLIT): drones of 100 g or more have needed registration in DIPS 2.0 since 2022-06-20, with built-in or external Remote ID. National pilot licenses and Level 4 flight started 2022-12-05; Level 3.5 started Dec 2023. No confirmed 2025–2026 changes.
R1-04-regulations-2025-2026.md - 6. Other countries (brief)
India: Drone Rules 2021 still apply, amended 2022 and 2023. MoCA published a draft Civil Drone (Promotion and Regulation) Bill, 2025 in Sept 2025 that would repeal the 2021 Rules and add type certification, mandatory third-party insurance and a green/yellow/red zone system in law, with penalties up to 3 years for red-zone violations. Still a draft [PENDING; R4-03 confirmed never introduced].
R1-04-regulations-2025-2026.md - 6. Other countries (brief)
New Zealand (CAA): updated Parts 101 and 102 took effect 2025-12-22, clarifying when Part 102 certification is needed, adding a Transport Instrument tool and creating a new Part 107 for testing new technology at approved research organisations. Basic Part 101 rules are unchanged: 400 ft limit, 4 km from aerodromes, within sight. [SECONDARY]
R1-04-regulations-2025-2026.md - 7. Flying with lithium batteries
Baseline (FAA PackSafe / IATA) [OFFICIAL]: spare lithium-ion drone batteries in carry-on only, terminals protected; up to 100 Wh no limit on number (airline limits aside); 101–160 Wh needs airline approval, maximum 2 spares; over 160 Wh forbidden on passenger aircraft.
R1-04-regulations-2025-2026.md - 7. Flying with lithium batteries
ICAO power bank rules [SECONDARY at round 1]: reportedly effective 2026-03-27 via Addendum No. 1 to the 2025–2026 Technical Instructions — maximum 2 power banks per passenger, carry-on only; no charging during flight, and airlines may ban use; not in overhead bins on many airlines. Airlines started their own limits earlier: Emirates Oct 2025, then Southwest, Lufthansa, Singapore Airlines, United and Japanese and Korean carriers through May 2026. Unclear whether drone batteries with USB outputs count — R4-03 concluded they are treated as spare batteries, but no published ruling exists.
R1-04-regulations-2025-2026.md - 7. Flying with lithium batteries
Drone-specific travel: the UK's lower 100 g threshold and Canada's SFOC for microdrones at events affect visitors. The FCC action does not stop travelers bringing already-authorized drones.
R1-04-regulations-2025-2026.md - 8. FPV video transmitter power
United States: under Part 15, 5.725–5.875 GHz analog transmitters under §15.249 are limited to about 50 mV/m at 3 m (roughly 1 mW EIRP); digital spread-spectrum systems under §15.247, such as DJI and some other digital systems, may use up to 1 W. Typical analog transmitters of 25 mW to 1 W+ need an amateur (Technician or higher) license under Part 97: 5.650–5.925 GHz, station ID required, no commercial use, no encryption — which makes them unsuitable for Part 107 paid work. (FCC Public Notice DA 18-581; AMA guide)
R1-04-regulations-2025-2026.md - 8. FPV video transmitter power
EU: licence-exempt 5.8 GHz video (5725–5875 MHz) is limited to 25 mW EIRP under ERC Recommendation 70-03 and national rules. Ham licences allow more power in some member states, but rules vary.
R1-04-regulations-2025-2026.md - 8. FPV video transmitter power
UK: licence-exempt limit is 25 mW EIRP (Ofcom IR 2030). Ofcom's amateur radio guidance (updated 2025-10-14) says drone control and FPV are "not compatible with the terms of the Licence"; airborne amateur use is allowed only in bands where amateurs are the primary user, at up to 500 mW EIRP, and 2.4 and 5 GHz are secondary bands, so no airborne use there. Ofcom suggests its UAS Radio Operator licence instead.

R2-01-flight-control-navigation.md - 3.2 DShot [V]
Bidirectional DShot: inverted signal, requires DShot300 or faster, with a ~30 µs line turnaround before the reply. The ESC replies on the same wire with eRPM data (3-bit exponent + 9-bit period + 4-bit CRC), GCR-encoded to 21 bits at 5/4 of the DShot bitrate. Extended DShot Telemetry (EDT) reuses unused code space for temperature, voltage, current and debug values. Commands 0–47 include beeps (1–5), ESC info (6), spin direction (7/8, 20/21), 3D mode (9/10), save settings (12) and telemetry/EDT enable (13/14).
R2-01-flight-control-navigation.md - 3.2 DShot [V]
Bitcraze added bidirectional DShot to the Crazyflie 2.1 Brushless in June 2026.

R2-01-flight-control-navigation.md - 4.2 Middleware, messaging and scripting
ArduPilot Lua: Lua 5.3.5; scripts in APM/scripts on the SD card, sandboxed with a VM-instruction budget; SCRHEAPSIZE default 43K–204.8K depending on CPU, complex applets need ~300K; requires 2 MB flash; not available on F4 [V].
R2-01-flight-control-navigation.md - 4.2 Middleware, messaging and scripting
SITL / Gazebo: the ArduPilot Gazebo plugin uses a JSON interface and supports Gazebo Garden and Harmonic (simvehicle.py -v ArduCopter -f gazebo-iris --model JSON) [V]. PX4 has px4sitl targets including px4sitlzenoh [V].
R2-01-flight-control-navigation.md - 4.2 Middleware, messaging and scripting
ROS 2 bridges: uXRCE-DDS — client on PX4, agent on the companion computer, over serial or UDP (default port 8888); topics mapped in ddstopics.yaml, defined in px4msgs, with message versioning [V]. Zenoh — experimental from PX4 v1.17; zenoh-pico on the FC talking to zenohd over TCP/UDP/multicast (no UART in the PX4 node); compatible with rmwzenoh (CDRv1); from ROS 2 Jazzy, key expressions include the type hash, which breaks Humble unless CONFIGZENOHKEYTYPEHASH=n [V].
R2-01-flight-control-navigation.md - 4.2 Middleware, messaging and scripting
PX4 v1.17 (2026-05-18): Altitude Cruise mode; TFLite Micro neural-network multicopter control; Septentrio jamming/spoofing reporting; MicroStrain, SBG and EULER-NAV INS drivers; MAVLink FTP path-traversal fixes [V].
R2-01-flight-control-navigation.md - 4.3 Flight modes
ArduCopter [V]: Loiter (GPS position and altitude hold, sticks command movement); PosHold (like Loiter but manual roll/pitch off-center); Auto (uploaded mission); Guided (GCS or companion-commanded targets); plus AltHold, Stabilize, Acro, RTL, SmartRTL, Brake, Follow, Throw, ZigZag.

QuadPlane (ArduPilot) [V]: VTOL modes QSTABILIZE, QHOVER, QLOITER, QLAND, QRTL, QACRO, QAUTOTUNE. Forward transition: once airspeed passes the threshold, VTOL motor assist ramps down over QTRANSITIONMS (default 5000 ms); QASSISTSPEED brings VTOL motors back to assist at low airspeed.
R2-01-flight-control-navigation.md - 4.4 INAV
Estimator: inertial position estimator fusing GPS, baro, rangefinder, optical flow and IMU, reporting quality as ESTNONE, ESTUSABLE or ESTTRUSTED [S]; historically a complementary-filter design weighted by inavw parameters [U].

R2-01-flight-control-navigation.md - 4.4 INAV
INAV 9.1 "magless" heading [V]: multicopters and VTOLs without a compass can be pointed at a known North heading before takeoff so nav modes work before GPS course-over-ground is available; position hold is better under weak GPS but depends more on the accelerometer, so clean vibration matters. u-blox defaults changed: nav rate 10 → 8 Hz, Galileo + BeiDou enabled.

Multi-band (L1+L5/E5a) removes first-order ionospheric error and helps reject multipath [U].
R2-01-flight-control-navigation.md - 5.2 Accuracy tiers
RTK corrections (RTCM3): reach the aircraft via GCS NTRIP client → MAVLink (GPSRTCMDATA), from a local base through the GCS, or over a transparent radio into a GPS UART. A base survey-in takes about 60 s for metre-level base position. Fix states are RTK Float and RTK Fixed [V].
R2-01-flight-control-navigation.md - 5.2 Accuracy tiers
PPK: raw logs from rover and base are post-processed; less sensitive to baseline distance and link dropouts, at the cost of turnaround [S]. Typical survey figures of 1–3 cm horizontal [U].
R2-01-flight-control-navigation.md - 5.2 Accuracy tiers
GPS-for-yaw (moving baseline): antennas at least 30 cm apart; F9P pairs (GPSTYPE 17/18, or 22/23 over DroneCAN) or Unicore UM982 (type 25); the driver validates heading using RTK-fixed status on the rover and a ±20% distance check [V].
R2-01-flight-control-navigation.md - 5.3 Compass problems and magless options
High-current wiring and ESCs distort the field, so the mag is usually on a GPS mast; ArduPilot also offers throttle/current-based compensation (compassmot) [U].
R2-01-flight-control-navigation.md - 5.3 Compass problems and magless options
Alternatives: ArduPilot's GSF yaw estimator [V]; dual-antenna GPS yaw [V]; INAV 9.1 magless heading [V]; Betaflight 2026.6 ignoring the mag unless trustmag = ON [V].

It detects objects of about 2.5 cm or larger, lets RTH climb about 10 m to clear obstacles, and is disabled in Sport mode [S]. In July 2026 the FCC proposed restrictions singling out LiDAR-equipped foreign drones [S].
R2-01-flight-control-navigation.md - 6.1 Sensing modalities

R2-01-flight-control-navigation.md - 6.1 Sensing modalities
DJI APAS (high level): fuses omnidirectional vision (plus LiDAR or ToF where fitted) into a local 3D obstacle map, then Bypass (replans around obstacles) or Brake (stops) while the pilot flies; does not work in Sport mode and degrades in low light, on textureless surfaces and near thin wires. DJI's support pages blocked automated fetching, so this is [U] beyond the Sport-mode note.
R2-01-flight-control-navigation.md - 6.1 Sensing modalities
Skydio: Skydio 2 used an NVIDIA TX2 and six 4K fisheye navigation cameras for 360° real-time 3D mapping, object recognition, motion prediction and path planning [V].

DJI FlySafe / GEO: zone types Warning, Enhanced Warning, Authorization, Restricted, Altitude and Regulatory Restricted. US change on 2025-01-13: DJI moved to advisory warnings based on FAA data, so most zones no longer lock the aircraft; altitude zones and regulatory restricted zones are still enforced. Custom and self-unlock workflows remain for legacy and enterprise users [S]. Other regions still use GEO 2.0 enforcement [U].
R2-01-flight-control-navigation.md - 8. Geofencing

R2-01-flight-control-navigation.md - Round 2 — Propulsion, power and airframes (engineering reference)
Research date: 2026-09-15. Extended by R4-01 (motor thrust tables, battery chemistry). Flags: [V] checked against the linked source; [C] calculated here from standard formulas with stated inputs; [U] common engineering value, unverified this pass.
R2-02-propulsion-power-airframes.md - 1.1 Naming and electromagnetics
Stator size code "WWHH": stator width (diameter) and height in mm — 2207 = 22 mm × 7 mm, 2809 = 28 mm × 9 mm, 0702 = 7 mm × 2 mm. Stator volume and torque capacity scale roughly with d²·h [U].
R2-02-propulsion-power-airframes.md - 1.1 Naming and electromagnetics
Pole count, e.g. 12N14P: 12 stator slots and 14 rotor magnets, so 7 pole pairs. Electrical RPM = mechanical RPM × 7, which is why Betaflight's motorpoles = 14 must match for bidirectional-DShot RPM filtering [U]. 12N14P is confirmed for the iFlight XING2 2809 [V] and T-Motor Velox V2808 [V]; whoop 07xx/08xx motors are often 9N12P [U].
R2-02-propulsion-power-airframes.md - 1.1 Naming and electromagnetics
KV: no-load RPM per volt. RPM₀ ≈ KV × V; under prop load expect roughly 75–90% of RPM₀ [U].
R2-02-propulsion-power-airframes.md - 1.1 Naming and electromagnetics
Torque constant (SI): Kt = 60 / (2π·KV) N·m/A, with τ = Kt·(I − I₀). 1750 KV → 0.00546; 1250 KV → 0.00764; 23000 KV → 0.000415 N·m/A [C]. For the same stator, lower KV means more turns, more torque per amp and less current for a given prop at higher voltage, but higher winding resistance.
R2-02-propulsion-power-airframes.md - 1.1 Naming and electromagnetics
Worked example: 1750 KV on a full 6S pack (25.2 V) gives RPM₀ ≈ 44,100 rpm; loaded on a 5.1" tri-blade that is about 33–37k rpm [C/U].

Independent test data. Mini Quad Test Bench measured the Sunnysky Edge Racing E-R2207 (nominal 1800 KV, measured 1870 KV; 35.2 g) on 6S: 2,098 g maximum thrust at 46 A [V]; 46 A × ~22–23 V ≈ 1,000–1,050 W, so about 2.0 g/W at full throttle [C]. R4-01 later transcribed the raw table and corrected the peak row to 2,053 g at 46.4 A and 1,069 W (1.92 g/W). Compare roughly 5–8 g/W at hover: g/W falls steeply as throttle rises. Other data sources: the Mini Quad Test Bench motor index, the Tyto Robotics / RCbenchmark thrust-stand database [U], and manufacturers' PDF thrust tables — often images that must be transcribed by hand.

R2-02-propulsion-power-airframes.md - 1.3 Magnets, bearings and heat
Above these limits magnets lose strength permanently, so KV rises and torque falls; winding enamel is usually rated class 180–220 °C [U]. Bearings are 9×4×4 or 9×3×4 mm on 22xx motors (EZO, NMB, NSK) and 11×5×5 mm on 28xx [V for XING2]; crash damage shows as rough spin and rising I₀. Practical limit: bells too hot to hold (above about 60–70 °C right after landing) usually indicate a tune/filter problem or overpropping [U].
R2-02-propulsion-power-airframes.md - 1.4 Brushed coreless motors
Used in toys and legacy micros, sizes 615, 716 and 8520 [U]. No stator iron, so no cogging, and they can be driven by a single MOSFET PWM from the FC. Brushes wear over tens of hours, efficiency is lower, and power falls as the motor heats.
R2-02-propulsion-power-airframes.md - 2.1 Naming and trade-offs
Naming: D × P × blades, in inches. 5×4.3×3 = 5" diameter, 4.3" geometric pitch, 3 blades; 51466 = 5.1" × 4.66" pitch.
R2-02-propulsion-power-airframes.md - 2.1 Naming and trade-offs
Blade count: more blades give more thrust for a given diameter and better throttle authority, at the cost of higher power per gram of thrust. Two blades are most efficient; three are the 5" freestyle standard [U].
R2-02-propulsion-power-airframes.md - 2.1 Naming and trade-offs
Materials: glass-fibre-reinforced PC/nylon for 5" (flexible, survives crashes); carbon fibre for 7"+ and cinelifters (stiff, efficient, dangerous, can shatter) [U].
R2-02-propulsion-power-airframes.md - 2.1 Naming and trade-offs
Tip speed: Vtip = π·D·n. 5.1" at 35,000 rpm ≈ 237 m/s (Mach 0.69); 7" at 26,000 rpm ≈ 242 m/s [C]. Above about Mach 0.6–0.7 compressibility losses and noise rise sharply; noise roughly scales with tip speed to the 5th or 6th power [U], which is why cinematic and low-noise builds use bigger, slower props.
R2-02-propulsion-power-airframes.md - 2.2 Momentum (actuator-disk) theory
Ideal induced hover power per rotor: Pideal = T^1.5 / √(2ρA); induced velocity vi = √(T/(2ρA)) [textbook: Leishman; U].
R2-02-propulsion-power-airframes.md - 2.2 Momentum (actuator-disk) theory
Real shaft power: Pshaft = Pideal / FM; electrical Pelec = Pshaft / ηmotor+ESC. Figure of merit is typically about 0.4–0.6 for small FPV props and 0.6–0.75 for large optimised multirotor props [U]; η is about 0.7–0.85 [U].
R2-02-propulsion-power-airframes.md - 2.2 Momentum (actuator-disk) theory
Disk loading: DL = T/A. Ideal power per newton ∝ √DL, so a larger rotor area needs less power for the same thrust.

With the same mass, 7" props need about 27% less ideal power than 5" props (√(A₅/A₇) = 0.73).
R2-02-propulsion-power-airframes.md - 2.3 Ducts (cinewhoops)
Ideal case: a ducted rotor with exit-area ratio σd has P = T^1.5/√(4σdρA); with σd = 1 that is a 29% power saving (1/√2) at equal thrust, because the duct lip carries part of the thrust [U, textbook].
R2-02-propulsion-power-airframes.md - 2.3 Ducts (cinewhoops)
Real hobby ducts: large tip gaps (over about 1% of D), short ducts with no diffuser, duct mass and extra drag in forward flight often wipe out most of the gain, so net efficiency is frequently no better than open props [U]. The practical benefits are prop guarding, less tip-vortex noise and better static thrust per diameter.
R2-02-propulsion-power-airframes.md - 3. ESCs
Current ratings: 5" 6S freestyle uses 45–60 A 4-in-1 boards; 7" and cinelifters 55–80 A; whoops 5–12 A AIO boards. Ratings are "continuous with airflow" and marketing-driven; MOSFET thermal mass and cooling are the real limit [U].
R2-02-propulsion-power-airframes.md - 3. ESCs
MOSFETs: conduction loss per switch is I²·Rds(on), about 0.7–3 mΩ on quality 30–40 V parts [U]. 30 V MOSFETs on 6S (25.2 V full) leave little margin for inductive spikes, so 40 V parts are preferred [U].
R2-02-propulsion-power-airframes.md - 3. ESCs
Gate drivers: discrete half-bridge drivers (e.g., Fortior FD6288-class) set edge speed, trading switching loss against EMI and ringing [U].
R2-02-propulsion-power-airframes.md - 3. ESCs
Firmware and MCUs: Bluejay runs on SiLabs EFM8BB21/BB1, with newer releases adding BB51, and adds bidirectional DShot (RPM telemetry) and selectable PWM of 24 / 48 / 96 kHz [V]. AM32 supports STSPIN32F0, STM32F051, STM32G071, GD32E230, AT32F415 and AT32F421 (CKS32F051 not recommended) with DShot 300/600, bidirectional DShot, KISS telemetry, variable PWM frequency and sinusoidal startup for big motors [V]. BLHeli32 development ended in 2024 and AM32 became the default 32-bit firmware [U].
R2-02-propulsion-power-airframes.md - 3. ESCs
PWM frequency: higher (48–96 kHz) gives smoother low-throttle response and a quieter whine band but more switching loss and heat; lower (24 kHz) runs cooler and more efficiently but feels less responsive [V].
R2-02-propulsion-power-airframes.md - 3. ESCs
Damped light / active braking: complementary (synchronous) switching drives the low-side FET during off-time, actively decelerating the motor and returning energy to the bus, which sharpens prop-wash handling [U]. That regenerated energy is one source of voltage spikes.
R2-02-propulsion-power-airframes.md - 3. ESCs
Capacitors: a low-ESR electrolytic across the battery pads absorbs spikes from lead inductance and braking regeneration [U]; typical choice is 35 V 470–1000 µF on 6S (50 V on 8S). Leaving it off is a leading cause of blown MOSFETs and gyro noise.
R2-02-propulsion-power-airframes.md - 3. ESCs
Current sensing and telemetry: a shunt resistor with an amplifier feeds the FC ADC for mAh counting; Extended DShot Telemetry can report per-ESC temperature, voltage and current [U].

R2-02-propulsion-power-airframes.md - 4.3 LiPo energy density, C-rating and sag
LiPo energy density: about 140–200 Wh/kg; high-C FPV packs sit near the lower end [U].
R2-02-propulsion-power-airframes.md - 4.3 LiPo energy density, C-rating and sag
C-rating reality: label C ratings are not standardised; internal resistance is the objective metric. Sag: ΔV = I·Rpack; loss: P = I²·R. A good 6S 1300–1500 mAh FPV LiPo is about 2–4 mΩ per cell when new [U].
R2-02-propulsion-power-airframes.md - 4.3 LiPo energy density, C-rating and sag
Sag example [C]: 6S LiPo at 3 mΩ/cell plus 2 mΩ of wiring/connector = 20 mΩ. At a 120 A punch, ΔV = 2.4 V and 288 W is lost as heat. The same 120 A burst is impossible on 6S1P P50B (81 mΩ pack, 60 A rating); at 40 A on that pack ΔV = 3.24 V and 130 W is lost — which is why Li-ion suits cruise, not freestyle.
R2-02-propulsion-power-airframes.md - 4.3 LiPo energy density, C-rating and sag
Rule-of-thumb sustainable current: about ΔVallowedpercell / Rcell; with 0.5 V and 3 mΩ that is about 167 A [C].
R2-02-propulsion-power-airframes.md - 4.3 LiPo energy density, C-rating and sag
Cycle life: LiPo is about 150–300 cycles in hard FPV use [U]; Li-ion has 500–1,400 datasheet cycles [V].
R2-02-propulsion-power-airframes.md - 4.4 Safety, transport, charging and connectors
Thermal runaway: separator shrinkage or melt around 130 °C (PE) leads to an internal short; around 150–250 °C exothermic decomposition begins (SEI breakdown, then electrolyte, then NMC cathode releasing oxygen) and heating self-accelerates, ending in venting and fire [U]. Triggers: puncture, overcharge, external short, cold charging (lithium plating).

UN38.3 transport tests [V]: T1 altitude simulation, T2 thermal cycling, T3 vibration, T4 shock, T5 external short, T6 impact/crush, T7 overcharge, T8 forced discharge. IEC 62133-2 covers portable-cell safety. Air carriage (IATA) limits are ≤100 Wh without approval and 100–160 Wh with airline approval [U].
R2-02-propulsion-power-airframes.md - 4.4 Safety, transport, charging and connectors
Charging: balance charge at 1C by default (many FPV LiPos accept 2–5C but age faster); store at 3.80–3.85 V per cell; never charge a puffed or cold pack [U]. DJI Mini 5 Pro battery charge window: 5–40 °C [V].
R2-02-propulsion-power-airframes.md - 4.4 Safety, transport, charging and connectors
Parallel charging risks: packs must be within about 0.1 V/cell before connecting or large equalisation currents flow; every pack must have the same cell count; a single charger fault affects all packs [U].

DJI Mini-series packs are Li-ion — the Mini 5 Pro standard pack is 2,788 mAh [V] (later confirmed 7.0 V / 19.52 Wh; Plus pack 4,680 mAh / 33.51 Wh in R4-02).

Flight time: tmin ≈ (EusableWh × 60) / PavgW, with Eusable = Vnom × Ah × DoD (about 0.8 for LiPo, 0.85–0.9 for Li-ion at low C).
R2-02-propulsion-power-airframes.md - 5. Power budgeting and flight time
Hover throttle: thrust ∝ ω², so throttlehover ≈ √(1/TWR) as a first approximation; real Betaflight hover throttle is often lower because of motor/ESC nonlinearity and throttle curves [U]. TWR 10:1 gives about 32% (2:1 about 71%) [C].
R2-02-propulsion-power-airframes.md - 5. Power budgeting and flight time
5" freestyle, 6S 1300 mAh LiPo (~650 g AUW): 22.2 V × 1.3 Ah = 28.9 Wh, usable at 80% = 23.1 Wh. At 300 W → 4.6 min; 400 W → 3.5 min; 600 W → 2.3 min — matching the real-world 3–5 min. Hover alone (about 100–130 W) would give about 11–14 min.

Carbon fibre: 3K twill face with T700 (or T300) fibre; arm thickness 5–6 mm for 5" freestyle and 6–8 mm for 7"+; plates 2–3 mm [U]. Unidirectional plates are stiffer per gram than twill. Always chamfer and seal edges — carbon is conductive, so exposed fibres can short electronics.

Frame geometries [U]: true X (symmetric motor spacing, equal pitch/roll inertia, easier tuning); stretched X (longer front-to-back, better pitch authority, racing); squashed X (longer side-to-side); deadcat (front arms swept wide to clear the camera view); H (stiff box body and easy stacking, but more mass and uneven arm loading).

Resonance and filtering: first bending mode of an arm or plate f ≈ (1/2π)·√(k/meff). Motor noise fundamental is rpm/60 — on a 5" 6S that is about 200–250 Hz at hover and over 500 Hz at full throttle, with harmonics from blade count and pole count. A stiff frame pushes structural modes above the RPM-filter and dynamic-notch range, or keeps them narrow, lowering gyro-filter delay so PID gains can run higher. Floppy arms or loose standoffs create broadband 80–200 Hz noise that filters cannot remove cleanly [U; frequencies C].
R2-02-propulsion-power-airframes.md - 6. Airframes
Soft mounting: TPU or silicone grommets for the FC (and sometimes motors) isolate high-frequency noise; too soft lets the FC shift or resonate, causing low-frequency oscillation [U].

Worked example [C]: generic 1.2 m span, 2.5 kg, S = 0.30 m² → wing loading 83 g/dm², AR 4.8. With CLmax 1.2, Vs ≈ 10.5 m/s. Cruise at 18 m/s with L/D 10: D = 2.45 N, Preq = 44 W, electrical ≈ 92 W (η 0.48). A 2.5 kg multirotor hovering on 10" props needs about 350–450 W — the core argument for lift+cruise VTOL.

R2-02-propulsion-power-airframes.md - 7. Fixed-wing and VTOL basics
VTOL configurations [U trade-offs; ArduPilot supports all three as QuadPlane variants]:
R2-02-propulsion-power-airframes.md - 7. Fixed-wing and VTOL basics
Quadplane (separate lift + cruise motors) — Simplest and most robust; easy transitions — Lift motors are dead weight and drag in cruise (~10–20% range penalty)
R2-02-propulsion-power-airframes.md - 7. Fixed-wing and VTOL basics
Tiltrotor (continuous, binary or vectored-yaw) — Shares motors; better cruise efficiency — Mechanical complexity; tilt servo is a single-point failure; transition tuning
R2-02-propulsion-power-airframes.md - 7. Fixed-wing and VTOL basics
Tailsitter — No extra actuators; lightest — Poor hover wind tolerance (the whole wing is a sail); awkward landing attitude and camera orientation
R2-02-propulsion-power-airframes.md - 7. Fixed-wing and VTOL basics
HEEWING T2 Cruza VTOL (PNP) [V]: 1,200 mm span; 2.0–3.5 kg takeoff weight; 3× FX-3110 680 KV motors (2 tilting front, 1 rear — a tricopter tiltrotor); 6S LiPo 3,500–7,800 mAh on XT60; 15–20 min claimed endurance; optional FX-405 flight controller running ArduPilot. The manufacturer figure is well below the idealised cruise calculation above because real drag, hover and transition segments and reserves dominate.
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Air density: ρ = p/(R·T), R = 287 J/(kg·K). At fixed RPM thrust ∝ ρ; for the same thrust, hover power ∝ 1/√ρ.
R2-02-propulsion-power-airframes.md - 8. Environmental factors
2,000 m ISA (ρ ≈ 1.007, σ = 0.82): about 18% less static thrust per rpm and about 10% more hover power [C].
R2-02-propulsion-power-airframes.md - 8. Environmental factors
35 °C at sea level (ρ = 1.146, σ = 0.935): about 6.5% less thrust and about 3.4% more hover power [C].
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Combined hot-and-high (e.g., 3,000 m at 30 °C, σ ≈ 0.70) cuts thrust margin by about 30% [C/U].
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Cold batteries: IR rises sharply below about 10 °C and roughly doubles or more near 0 °C versus 25 °C [U], causing more sag and earlier low-voltage cutoff. Pre-warm packs to about 20–30 °C; do not charge below 5 °C [V]. Enterprise packs self-heat (e.g., Autel EVO Max 8070 mAh 14.88 V pack [V retailer]).
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Wind resistance classes map to the Beaufort scale [U standard]:
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Class — Upper wind speed — Example
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Level 5 — ≤10.7 m/s (Beaufort 5 is 8.0–10.7 m/s) — DJI Mini 2 SE, Mini 4 Pro [V]
R2-02-propulsion-power-airframes.md - 8. Environmental factors
Level 7 — ≤17.1 m/s — HoverAir Aqua claims Level 7 ("up to 33 knots") [V]
R2-02-propulsion-power-airframes.md - 8. Environmental factors
A rule of thumb is to keep maximum sustained wind below about 2/3 of the drone's top speed [U].
R2-02-propulsion-power-airframes.md - 8. Environmental factors
IP ratings (IEC 60529): first digit solids (6 = dust-tight), second liquids (5 = water jets, 7 = immersion to 1 m for 30 min). HoverAir Aqua: IP67, positive buoyancy, 249 g, 23 min, 55 km/h [V]. Enterprise example: DJI Matrice 4-series and Matrice 400 are IP55 [U].
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Intelligent Energy IE-SOAR 800 [V]: 800 W continuous (up to 7.5 kW peak with a hybrid buffer battery); 1,450 g module plus 315 g regulator; 24–48 V configurable; 350 bar cylinders; −5 to 40 °C; claims "up to 7 h" flight and 600–800 Wh/kg at system level. A Gen 2 800 W unit is marketed as a drop-in 6S–12S battery replacement [V].
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Doosan Mobility Innovation DS30W [V]: 2.7 kW fuel cell; 10.8 L or 7 L tanks; MTOW 24.9 kg; 3 kg payload; 120 min without payload; 12 m/s wind rating.
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Barriers: hydrogen logistics, pressure-vessel transport rules, cost.
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Hybrid gas-electric multirotors: a small 2-stroke or rotary generator plus a buffer pack; claims are 2–5 h with kg-class payloads; drawbacks are noise, vibration isolation and maintenance [U, unverified].
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Solar HAPS (brief): ultra-light span-loaded fixed wings; multi-week flights demonstrated (e.g., Airbus Zephyr) [U]; night-time battery energy density is the gating factor.
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Silicon-anode and semi-solid cells:
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Amprius SiCore: 450 Wh/kg and 950 Wh/L cell launched 2025, UN38.3 expected Q2 2025 [V]. SiCore 500 announced September 2026: 500 Wh/kg at 1C continuous, SAE JA1016 sUAS pouch format, built on conventional Li-ion lines, optimised for low-rate HAPS and fixed-wing use; commercial availability expected Q4 2026 [V]. The 1C rating means it is not suited to multirotor punch-outs.
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
Tattu/Grepow semi-solid UAV packs: four tiers — 280, 300, 330 and 350 Wh/kg (TARBG28/30/33/35), up to 24S [V]. Grepow claims 1,200+ cycles, 2C charging, −40 to 60 °C operation, silicon-carbon anode with high-nickel NMC, and solid + gel electrolyte [V]. Retail example: Tattu 350 Wh/kg 33,000 mAh 14S 10C pack.
R2-02-propulsion-power-airframes.md - 9. Emerging power sources
DJI and Autel status: no official evidence that any shipping DJI or Autel consumer or enterprise battery uses semi-solid or solid-state cells as of Sept 2026. DJI Mini 5 Pro packs are listed as Li-ion [V]; articles linking DJI to solid-state batteries are explicitly rumor [V]. R4-01 confirmed no semi-solid or silicon-anode hobby/FPV pack exists — that line is commercial-UAV only.

Band — Range — Typical drone use — Regulatory notes
R2-03-rf-video-imaging.md - 1.1 Frequency bands
433 MHz — 433.05–434.79 MHz — Long-range RC or telemetry (EU) — ISM in ITU Region 1; in the US it sits in the 70 cm amateur band, so a licence is needed [UNVERIFIED detail]
R2-03-rf-video-imaging.md - 1.1 Frequency bands
868 MHz — 863–870 MHz — Crossfire EU, ELRS 868 — EU SRD band; typically 25 mW ERP with duty-cycle or LBT rules (ERC Rec 70-03)
R2-03-rf-video-imaging.md - 1.1 Frequency bands
915 MHz — 902–928 MHz — Crossfire/ELRS 915 (FCC), Autel SkyLink 900 MHz (FCC only) — FCC Part 15.247
R2-03-rf-video-imaging.md - 1.1 Frequency bands
1.2/1.3 GHz — 1240–1300 MHz (US) — Legacy long-range analog video — Amateur band, licence required; can interfere with GNSS harmonics [UNVERIFIED]
R2-03-rf-video-imaging.md - 1.1 Frequency bands
2.4 GHz — 2400–2483.5 MHz — ELRS 2.4, Tracer, FrSky, DJI/Autel downlink — FCC: 1 W conducted with a 6 dBi antenna allowance, about 36 dBm EIRP; CE: 20 dBm EIRP (EN 300 328)
R2-03-rf-video-imaging.md - 1.1 Frequency bands
5.1/5.2 GHz — 5150–5250 MHz — DJI O4 in CE regions — DJI declares <23 dBm CE
R2-03-rf-video-imaging.md - 1.1 Frequency bands
5.8 GHz — 5725–5850 MHz ISM; FPV bands run 5645–5945 — Analog, HDZero, DJI, Walksnail, OpenIPC — CE SRD: 25 mW (14 dBm) EIRP; Raceband R1 and R8 fall outside 5725–5850, so in the US they require an amateur licence
R2-03-rf-video-imaging.md - 1.2 Free-space path loss
FSPL(dB) = 20·log10(dkm) + 20·log10(fMHz) + 32.44
R2-03-rf-video-imaging.md - 1.2 Free-space path loss
Rules of thumb: doubling distance adds 6 dB; at equal distance 5.8 GHz loses about 16 dB more than 915 MHz; every +6 dB of link budget doubles free-space range.
R2-03-rf-video-imaging.md - 1.3 Link budget
Margin = PTX(dBm) + GTX(dBi) + GRX(dBi) − FSPL − Lcables − SensitivityRX(dBm)
R2-03-rf-video-imaging.md - 1.3 Link budget
Maximum range: dkm = 10^((P+Gt+Gr−S−FadeMargin−32.44−20·log10 fMHz)/20)
R2-03-rf-video-imaging.md - 1.3 Link budget
Example A — ELRS 2.4 GHz at 250 Hz LoRa: sensitivity −108 dBm, TX 100 mW (20 dBm), 2 dBi antennas both ends → 132 dB allowable path loss → d ≈ 39 km with no fade margin, matching the ELRS claim of "over 40 km at 250 Hz 100 mW". With a realistic 10 dB fade margin, about 12.3 km.
R2-03-rf-video-imaging.md - 1.3 Link budget
Example B — ELRS 900 MHz at 100 Hz LoRa: sensitivity −117 dBm, same TX and antennas → 131 dB with a 10 dB margin → about 93 km in free space. In practice the radio horizon, Fresnel clearance and antenna pattern nulls limit range long before that.
R2-03-rf-video-imaging.md - 1.3 Link budget
Fade margin: 10–20 dB is a sensible design target for multipath, body blocking and airframe shadowing.
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
First Fresnel zone radius: r₁(m) = 17.32·√(d1·d2 / (fGHz·D)), distances in km; at the midpoint r₁ = 8.66·√(Dkm/fGHz). Keep at least 60% clear.
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
Link — r₁ at midpoint — 60% clearance
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
5.8 GHz, 2 km — 5.1 m — 3.1 m
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
2.4 GHz, 5 km — 12.4 m — 7.5 m
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
915 MHz, 10 km — 28.6 m — 17.2 m
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
This is why a pilot standing at ground level loses a low-flying drone early even when the drone is visible.
R2-03-rf-video-imaging.md - 1.4 Fresnel zone and line of sight
Radio horizon (standard atmosphere, k = 4/3): dkm ≈ 4.12·(√h₁ + √h₂), heights in metres. A pilot antenna at 2 m and a drone at 120 m AGL gives about 51 km.
R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath

R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath
Helical (axial) — ~10–16 dBi — Narrow beam, circular polarization — Long-range ground station
R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath
Pagoda / cloverleaf / lollipop — ~1–3 dBi — Omni, circular polarization — Video TX and RX
R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath
Polarization: two linear antennas at 90° lose roughly 20 dB or more in theory; linear to circular costs 3 dB; RHCP to LHCP costs roughly 15–25 dB. Circular polarization rejects odd-order reflections (a reflection flips handedness), which is why it is standard for 5.8 GHz video near structures. RC links at 900 MHz and 2.4 GHz mostly use linear antennas.
R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath
Diversity types: antenna diversity (one radio chip switching between two antennas); true diversity (two radio chips, each with its own antenna); Gemini (true-diversity RX plus a dual-antenna TX sending the same packet on two frequencies about 40 MHz apart at 2.4 GHz or about 13 MHz at 900 MHz); Gemini Xrossband (GemX) (2.4 GHz and 900 MHz simultaneously on LR1121 hardware).
R2-03-rf-video-imaging.md - 1.5 Antennas, polarization, diversity and multipath
Multipath: reflected copies cause frequency-selective fades. Digital video counters this with OFDM, MIMO (e.g., DJI 2T2R or 2T4R) and FEC; analog shows it as tearing or breakup.
R2-03-rf-video-imaging.md - 2.1 ExpressLRS
Chips: Semtech SX1276/77 (900 MHz, LoRa and FSK); SX1280/81 (2.4 GHz, LoRa, FLRC, GFSK); LR1121 (sub-GHz plus 2.4 GHz on one chip, enabling dual-band and GemX). ELRS 4.1 refactoring lays groundwork for the LR2021. LoRa bandwidth and spreading factors used by ELRS (about 812 kHz BW at 2.4 GHz, 500 kHz at 900 MHz, SF5–SF9) were [UNVERIFIED] at round 2 and later read from source in R3-04/R4-01.
R2-03-rf-video-imaging.md - 2.1 ExpressLRS
Modulation trade-off: LoRa (chirp spread spectrum) gives the best sensitivity at low rates; FLRC (a GFSK variant with coding) gives low latency and high rates with worse sensitivity (SX1280 datasheet lists FLRC data rates of 0.52–1.3 Mbps [UNVERIFIED]); K modes are FSK with FEC, added for LR1121 at 2.4 GHz.

OTA packet (high level): packet types RCDATA, SYNC and DATA (telemetry, MSP, AirPort). OTA4 (standard) uses CRC-14 and packs stick channels as 10-bit values, with switches as 3-bit index plus 3-bit value (Hybrid) or 6-bit (Wide); OTA8 (Full Res) uses CRC-16. The CRC seed comes from UID bytes XOR'd with the OTA version, so mismatched firmware versions do not link. Byte sizes of 8 (OTA4) and 13 (OTA8) were [UNVERIFIED] here and confirmed in R3-04.

DJI lists the recording format only as an MP4 container; the codec and waveform were [UNVERIFIED] here. R4-01 later established H.265, with the 100/130 Mbps figures being recording bitrates and the live feed capped around 60 Mbps.
R2-03-rf-video-imaging.md - 3.3 DJI Avata 360 (O4+)
Launched Mar 26–27, 2026: dual 1/1.1-inch sensors, f/1.9, 8K60 in 360° mode or 4K60 single-lens; 120 MP 360° stills; 10-bit, D-Log M; 42 GB internal storage; O4+ transmission up to 20 km FCC; flight time 22–23 min. The dji.com spec page was blocked, so bitrate, latency and EIRP were [UNVERIFIED] (R4-01: 60 Mbps live, ~130 ms controller-screen latency, 180 Mbps H.265 recording).
R2-03-rf-video-imaging.md - 3.4 Walksnail Avatar and Ascent (Caddx)
Avatar HD Pro Kit: 1/1.8" Starvis II sensor, 1080p/120 capture, H.265; 22 ms latency and 4 km range claims; 160° FOV; 8 GB onboard storage; Gyroflow-capable gyro logging; Goggles X run 1080p/100. Maximum bitrate ~50 Mbps was [UNVERIFIED] here and confirmed in R4-01.
R2-03-rf-video-imaging.md - 3.4 Walksnail Avatar and Ascent (Caddx)
Status in 2026: development has "noticeably slowed" (about three firmware updates). Caddx also sells the budget "Ascent" system — air unit around $36, goggles around $149, about 60 ms latency.
R2-03-rf-video-imaging.md - 3.5 HDZero
Official claims: based on the Divimath DM5680 and DM6300; "uncompressed video"; glass-to-glass latency under 3 ms; "<1 ms fixed latency"; errors affect individual pixels or blocks rather than freezing the frame; MSP DisplayPort canvas OSD and SmartAudio support; 7.3 km LOS record.
R2-03-rf-video-imaging.md - 3.5 HDZero
Modes: 720p60, 1080p30, and 540p90 (HDZero goggles only); fixed latency independent of signal strength, with goggles frame-synchronised to the VTX; HDZero goggles quote 4 ms glass-to-glass. Power: Race and Whoop VTX at 25/200 mW; Freestyle up to 1 W (licensed use only). Uses Raceband-compatible channels, so it can share analog race timing.
R2-03-rf-video-imaging.md - 3.5 HDZero
Engineering check on "uncompressed": raw 1280×720 YUV 4:2:0 at 8 bit and 60 fps is about 660 Mbps, which cannot fit a single ~20–30 MHz FPV channel. The link must use lightweight intra-frame coding (widely described as wavelet-like) with no inter-frame compression and no frame buffering, so a more accurate description is "no temporal compression, no frame buffering." R4-01 identified it as Joint Source Channel Coding on the DM5680(T) + DM6300.

R2-03-rf-video-imaging.md - 3.6 OpenIPC (open-source digital)
How wfb-ng works: the air side uses raw 802.11 packet injection in broadcast mode with no association, ACK or retry; the ground card listens in monitor mode; Reed-Solomon-style FEC recovers lost packets. Video is H.265 or H.264; telemetry is MAVLink or MSP.
R2-03-rf-video-imaging.md - 3.6 OpenIPC (open-source digital)
Latency on the wiki: about 60 ms at 720p60 and about 80 ms at 1080p60 — dated figures; current SSC338Q builds are reported far lower [UNVERIFIED] (R4-01 found one SSC30KQ 720p measurement averaging 28.3 ms).
R2-03-rf-video-imaging.md - 3.6 OpenIPC (open-source digital)
Adaptive Link: the ground side (alinkgs) computes a score from 1000 to 2000 from RSSI and SNR weighted 0.3/0.7; the drone then adjusts MCS (0–2), bitrate (about 2–9 Mbps), FEC (e.g., 8/12), TX power and guard interval.

(R4-02 later found manufacturer range figures of 13 km FCC / 23 km high-capacity.)
R2-03-rf-video-imaging.md - 4. Consumer camera-drone transmission
Why FCC range exceeds CE range: at 5.8 GHz, EU SRD rules cap EIRP at 25 mW (14 dBm) while FCC Part 15.247 allows about 30–36 dBm. The 19 dB gap between DJI's 33 dBm FCC and 14 dBm CE figures equals about 8.9× the free-space range. CE units shift to 5.1 GHz (23 dBm) and 2.4 GHz (20 dBm) to recover part of that; against 33 dBm FCC, 23 dBm still means about 3.2× less free-space range. Adaptive bitrate and MIMO narrow the gap further, which is why published ranges (15 km FCC vs 8 km CE on O4 Pro) differ by less than 8.9×. Region is set by GPS/geo-location in firmware; readers should use the mode that is legal where they fly.

Pixel pitch = sensor width ÷ horizontal pixels. The Mavic 4 Pro's 100 MP 4/3 sensor works out to about 1.5 µm; full-frame 35 MP is about 4.9 µm. Larger pixels mean more full-well capacity, so more dynamic range and better low-light signal-to-noise.

R2-03-rf-video-imaging.md - 6.2 Camera specs (2025–26)
Action cameras: DJI Osmo Action 6 (Nov 2025) — 1/1.1", variable f/2.0–4.0, 8K30, 4K120, 120 Mbps, D-Log M, RockSteady 3.0/3.0+ and HorizonSteady. GoPro Mission 1 Pro (Apr 2026) — 1" 50 MP, 8K60, 8K30 open-gate, 4K240, 240 Mbps, 10-bit GP-Log2 and HLG, with an interchangeable-lens (MFT) variant. GoPro HERO13/14 and Insta360 Ace Pro 2 were not verified in this pass. "Naked" GoPros are cameras stripped of their housing to save weight, keeping GPMF gyro data.
R2-03-rf-video-imaging.md - 6.3 Shutter, codecs and exposure
Rolling shutter: rows are read out sequentially, so skew = subject angular speed × readout time; jello comes from motor or prop vibration at frequencies comparable to the readout rate. Consumer sensors typically read out in about 10–30 ms [UNVERIFIED generic]. Fixes: soft-mount the camera, balance the props, use gyro-based rolling-shutter correction (Gyroflow).
R2-03-rf-video-imaging.md - 6.3 Shutter, codecs and exposure
Global and mechanical shutters: global-shutter sensors expose every row simultaneously and are rare in drones; mapping payloads use mechanical leaf shutters instead (e.g., 1/2000 s on Mavic 3 Enterprise and Zenmuse P1 [UNVERIFIED]) to avoid geometric distortion in photogrammetry.
R2-03-rf-video-imaging.md - 6.3 Shutter, codecs and exposure
Bit depth: 8-bit has 256 levels per channel, 10-bit has 1024; 10-bit is needed for log profiles to avoid banding when grading. Grade log footage with a LUT — either a technical Rec.709 transform or a creative look.
R2-03-rf-video-imaging.md - 6.3 Shutter, codecs and exposure
Codecs: H.264 is most compatible; H.265 gives about 2× efficiency at the same quality but is slower to decode; ALL-I and ProRes intra-frame codecs edit fastest but need very high bitrates.
R2-03-rf-video-imaging.md - 6.3 Shutter, codecs and exposure
180° shutter rule and ND filters: shutter = 1/(2 × fps) — 1/50 at 24–25 fps, 1/120 at 60 fps. Worked example: sunny-16 at ISO 100 and f/2.8 gives about 1/3200 s, so reaching 1/50 needs about 6 stops — an ND64. ND strength in stops = log2(ND factor): ND16 = 4, ND32 = 5, ND64 = 6.
R2-03-rf-video-imaging.md - 6.4 Stabilization
Mechanical gimbal: a 3-axis brushless gimbal uses an IMU plus field-oriented motor control to cancel pitch, roll and yaw; it preserves the full sensor area and handles in-frame motion blur better than EIS.
R2-03-rf-video-imaging.md - 6.4 Stabilization
Electronic stabilization (EIS): crops and warps each frame using gyro data synced to sensor readout (RockSteady, HyperSmooth, ReelSteady). In-frame motion blur cannot be removed, so use a fast shutter or low ND when relying on EIS.
R2-03-rf-video-imaging.md - 6.4 Stabilization
Gyroflow: stabilizes in post using gyro logs recorded with the video (GoPro GPMF, Sony, Insta360, DJI, RunCam, Caddx); can also use Betaflight or ArduPilot blackbox logs as an external gyro source; applies lens profiles and rolling-shutter correction.
R2-03-rf-video-imaging.md - 6.4 Stabilization
360° capture: two fisheye lenses of more than 180° each, with the stitch line hidden along the airframe; software masks the drone out (the "invisible drone" effect on the A1 and Avata 360). Resolution figures such as "8K" describe the whole sphere, so any single viewing direction is far lower.
R2-03-rf-video-imaging.md - 6.5 Thermal (enterprise)
Zenmuse H30T: uncooled VOx microbolometer, 1280×1024 at 30 fps, 12 µm pitch, NETD ≤50 mK at f/1.0, 8–14 µm; radiometric range −20 to 450 °C high gain and 0 to 1600 °C low gain; also a 40 MP 1/1.8" zoom camera (to 809 mm equivalent), a 48 MP 1/1.3" wide camera and a 3000 m laser rangefinder.

R2-03-rf-video-imaging.md - 6.5 Thermal (enterprise)
Radiometric means every pixel stores a calibrated temperature value rather than a display colour; export variants may be limited to 9 Hz or below [UNVERIFIED].
R2-03-rf-video-imaging.md - 6.6 Photogrammetry
Ground sample distance: GSD = (sensor width × altitude) ÷ (focal length × image width in px). Worked example with a 1" 20 MP camera (13.2 mm width, 5472 px, 8.8 mm focal) at 100 m: 2.74 cm/px. Halving altitude halves GSD.
R2-03-rf-video-imaging.md - 6.6 Photogrammetry
Flight planning: 70–80% front overlap and 60–80% side overlap; use a mechanical shutter to avoid rolling-shutter distortion, or fly slowly with rolling-shutter compensation; use RTK or PPK geotags (about 1 cm + 1 ppm) to reduce ground control points.

Notes: the MQ-9A fact sheet gives no ceiling or speed — the ~50,000 ft and ~240 KTAS figures often quoted come from GA marketing. A Gray Eagle 25M datasheet summary returned MQ-9B-like numbers, apparently a mix-up, so those were not used [UNVERIFIED] (R4-04 later obtained 17 m span, 1,905 kg MTOW, 40+ h, 25,000 ft, 167 KTAS, 200 hp HFE). MQ-25A: 76 aircraft planned; the budget line funds 3 aircraft for $771M.

R2-04-military-technical.md - Sensors (high level)
SIGINT / EW pods. Open architecture on Gray Eagle 25M lets EW and SIGINT pods be swapped plug-and-play [MFR]; Hermes 900 advertises EW payloads [MFR].
R2-04-military-technical.md - Datalinks and standards
LOS vs BLOS bands. Gray Eagle-family literature lists C-band LOS; X-, Ku- or Ka-band SATCOM over the horizon; Inmarsat as backup [MFR]. Tactical Common Data Link runs in Ku-band, 14.5–15.38 GHz.
R2-04-military-technical.md - Datalinks and standards
SATCOM latency. A geostationary relay adds roughly 0.5 s per up-and-down round trip before any processing; totals of about 1–2 s are commonly cited. One academic text quotes USAF leadership describing 5–8 s delays on Predator controls flown beyond line of sight because of encryption overhead [CONTESTED; era- and architecture-dependent]. This latency is why launch and recovery were historically flown over LOS; GA-ASI has since demonstrated SATCOM-based automatic takeoff and landing on MQ-9B.
R2-04-military-technical.md - Datalinks and standards
STANAG 4586 (UAV control-system interoperability). Architecture: Core UCS, Vehicle Specific Module (VSM), Data Link Interface (DLI), Command & Control Interface (CCI). Five Levels of Interoperability: 1 indirect receipt of sensor data; 2 direct receipt; 3 payload control; 4 air-vehicle control (excluding launch and recovery); 5 launch and recovery control.
R2-04-military-technical.md - Datalinks and standards
STANAG 4609 (motion imagery). Video in MPEG-2 transport stream (H.264/MPEG-2) with KLV metadata; MISB ST 0601 "UAS Datalink Local Set" uses short keys for bandwidth-limited links, with synchronous or asynchronous metadata carriage.

Blue UAS. Two parts: the Cleared List (platforms) and the Framework (NDAA-compliant components vetted by third-party Recognized Assessors). As of 2025-11-19: 39+ systems and 165 components; 81 companies onboarded since 2020. The program moved from DIU to DCMA's US-X office (Palmdale) on 2025-12-03.
R2-04-military-technical.md - 3. Navigation (conceptual)
INS/GNSS fusion is the baseline. Baykar advertises "navigation with internal sensor fusion without dependency on GPS" on TB2 [MFR]; Orca XLUUV uses a Kalman-filtered INS aided by Doppler velocity log and depth sensors [MFR].
R2-04-military-technical.md - 3. Navigation (conceptual)
M-code GPS is the jam-resistant military signal. In Sept 2024 GAO reported continuing delays across space, ground and user-equipment segments, deficiencies in the first user-equipment increment, and risk of chip shortages.
R2-04-military-technical.md - 3. Navigation (conceptual)
Alternative PNT: vision/terrain-referenced navigation (matching sensor imagery to stored maps); magnetic anomaly navigation (MagNav) — in the DIU Transition of Quantum Sensing program, Honeywell's quantum MagNav flew 4 h 23 min on an Embraer 170 (June 2026), reporting 89% better position accuracy than traditional backup navigation, with C-17 tests planned later in 2026; celestial/star trackers (historically on high-altitude aircraft); LEO-satellite PNT (e.g., Iridium-based services).
R2-04-military-technical.md - 3. Navigation (conceptual)
Adversary GNSS receivers: Geran-2/3 reportedly carry a "Kometa-M12" multi-element anti-jam GNSS receiver alongside INS [REP, DIU].
R2-04-military-technical.md - 4. Autonomy
Spectrum of control: remotely piloted (pilot and sensor operator, as on the MQ-9 crew model); supervised autonomy (waypoint and auto-land modes — Raven already offers autonomous navigation, loiter and return-home [OFF]); collaborative autonomy (multiple vehicles coordinating under a human mission commander — CCAs, swarms).
R2-04-military-technical.md - 4. Autonomy
DoDD 3000.09 (reissued 2023-01-25): autonomous weapon system — "once activated, can select and engage targets without further intervention by a human operator"; semi-autonomous — engages "only individual targets or specific target groups that have been selected by a human operator"; operator-supervised (human-on-the-loop) — operators can monitor and halt engagements. Covered systems need senior review before development and again before fielding; the Deputy Secretary of Defense may waive review only for urgent military need. The directive does not ban such systems; it requires "appropriate levels of human judgment."
R2-04-military-technical.md - 4. Autonomy
A-GRA (Autonomy Government Reference Architecture): a government-owned standard so mission autonomy software can run on any compliant CCA, avoiding vendor lock-in. Collins "Sidekick" is paired with YFQ-42A and Shield AI Hivemind with YFQ-44A (reported Feb 2026).
R2-04-military-technical.md - 4. Autonomy
Commercial frameworks: Shield AI Hivemind — "end-to-end software for building and scaling AI pilots," GPS- and comms-denied operation, teaming, on 10+ platforms. Anduril Lattice — sensor-fusion and C2 software behind Sentry towers and Roadrunner.
R2-04-military-technical.md - 4. Autonomy
AI-assisted terminal guidance (trend only): vendors publicly advertise onboard target re-identification and link-loss operation (HX-2 is marketed as working without a datalink; Harop has an EO seeker). How it works is not described here.
R2-04-military-technical.md - 5. Fiber-optic FPV (overview)
History: Russia introduced them in summer 2024 and deployed them widely from early 2025; Ukraine began testing in March 2025 with first deliveries in April 2025. About 90% of drone fiber comes from China (OSW).
R2-04-military-technical.md - 5. Fiber-optic FPV (overview)
Reported spool lengths: 10 km (captured Russian drone); 20 km (Ukrainian trials, Apr 2025); ~40 km (Ukrainian model); 50 km on a 3.8 kg spool (Russian claim [UNVERIFIED]).
R2-04-military-technical.md - 5. Fiber-optic FPV (overview)
Weight penalty: a 10 km spool on the Russian KVN weighs about 2.3 kg [REP]. Ukraine's MoD figures show the trade-off — the Khyzhak 10 Lite carries less payload as spool length grows, and effective range on a 10 km spool is 8–9 km.
R2-04-military-technical.md - 5. Fiber-optic FPV (overview)
Limitations (reported): payload and agility fall as spool length grows; fibers can snag or break, and thickness choices trade strength for weight; accuracy degrades at long range; aircraft are single-use; the battlefield fills with fiber litter; supply depends on China. Benefit: immunity to RF jamming.
R2-04-military-technical.md - 6. Counter-UAS technical overview
Detection sensors. Radar: Ku-band KuRFS in the M-LIDS/FS-LIDS family (the Army plans 118 fixed and 33 mobile radars); X-band X-TAR3D on Skynex, up to 45 km. RF detection: passive sensing of control and video links. EO/IR: Anduril's Extended Range Sentry Tower (80 ft) reaches 7.5 mi with clear line of sight, or 5+ mi autonomous detection. Acoustic networks are also used, including against fiber-optic drones.

R3-03-adjacent-categories.md - 0. Why this matters for a hobby-drone site (key takeaways)
Rules for the whole US drone market changed in 2025–26, and the adjacent categories feel it first. Since the FCC Covered List action of 2025-12-22, new foreign-made UAS models cannot get FCC authorization. Only models authorized before that date (for example DJI Matrice 4/400, Dock 3, Agras T100/T55, FlyCart 30/100) can still be sold. On 2026-09-03 Section 232 tariffs took effect: 100% on thermal-equipped drones, docks and drones over 25 kg, and 25% on other drones up to 25 kg. That makes almost every DJI enterprise and agriculture product much more expensive in the US. [VERIFIED via R3-01; DroneXL 2026-09-02]

4.5 → 2025.12: the D-term numbers did not change behaviour: 4.5 stored the peak value as "D" and the base as dmin; 2025.12 renamed to base "D" + dmax (peak). Roll base 30 → peak 40, pitch 34 → 46 in both. Real default-behaviour changes were feedforward (2-point averaging, smoothing 25→65) and iterm windup semantics.

2025.12 → 2026.6: the only PID-profile default change is D-max boost: dmaxgain 37→0 (gyro-driven boost disabled) and dmaxadvance 20→35 (setpoint-driven boost). Commit history: rc1 had 37/20; PR #15221 (4 Jul 2026) set advance to 0; PR #15395 (commit b6bf0f5, 7 Jul 2026) changed to gain 0 / advance 35 "post decoupling of the two parameters". The official 2026.6 release-notes page still says dmaxadvance "now defaults to 0" — that text is stale vs the shipped source (35).

Filter cut-offs and counts unchanged, but the implementation changed: release notes say the biquad (DF1) was replaced by State Variable Filters (SVF) across gyro, PID (D-term notch/LPF "BIQUAD" option), RPM, dynamic-notch and servo paths (svfNotchInit, svfLowpassFilterInit in pidinit.c). CLI still shows the lowpass type as BIQUAD. D-term LPF limits are now clamped to 95 % of PID-loop Nyquist.

thrustlinear (0–150) re-derived to a 2nd-order Taylor form of ArduPilot MOTTHSTEXPO: c(x)=x·(1+e(1−x)(1+e(1−2x))), e = thrustlinear/100; source comments recommend ≈55 (5"), ≈65 (10"), ≈75 (20"+). Existing values give a slightly different curve (PR #15226).

IIM-42652 was mis-configured at ±4000 dps and corrected to ±2000 dps — effectively doubles loop gain; release notes say reset and retune PIDs. LSM6DSV16X 4000 dps register encoding also fixed. IST8310 default I2C address 0x0C→0x0E.

The market is real but hard to measure. Paid reports put the consumer drone market at about $5.9–6.0B in 2025, rising to about $6.5–7.3B in 2026. Forecast growth runs 11.6–14.1% a year [EST]. These reports ignore US regulatory shocks and do not break out FPV reliably. Quote them as ranges and never as fact.
R3-06-market-audience-business.md - 0. Executive takeaways
US policy is the most important content driver. On 2025-12-22 the FCC added all foreign-produced UAS and critical components to the Covered List. That blocks new FCC authorizations, so no new DJI models can launch in the US. Exemptions were extended or made permanent on 2026-07-21. A DJI suit in the Ninth Circuit is pending [V/SEC]. No retailer or industry sales data for US consumer drones in 2026 is public. Evidence is limited to reports of stock-outs (2025) and legal analysis.

The US audience is large. FAA figures are about 873k registered drones (502k recreational, 368k commercial) and 224k remote pilots certified (current FAA page) [V, counting method unclear, see §2]. TRUST reached about 852k by Aug 2024 [SEC]. AMA has about 165–195k members [CONFLICT]. MultiGP reports 30k+ pilots and 500 chapters [V]. The UK has about 510k active Flyer IDs and 370k Operator IDs (FOI, Oct 2025) [SEC].

Competitors are fragmented. News and training are crowded, while reference and data are open. News sites (DroneDJ, DroneXL, DroneLife) run on ads and affiliate income and get modest, volatile traffic. Training brands (Pilot Institute, UAV Coach/DPGS, Drone U) earn from courses. FPV education is concentrated in Oscar Liang (blog) and Joshua Bardwell (438k YouTube subscribers). Gaps: a neutral, dated US-policy tracker; a structured rules-by-country database; a model and spec database with FCC-authorization status; a reference for FPV engineering.

Course and FPV-retailer affiliates pay far better than Amazon. Rates: Pilot Institute 20%, RaceDayQuads 8% (72 h cookie), GEPRC 5%, BetaFPV 3%, DJI 5% via its own program or Awin (US/CA, no coupons or PPC). Amazon pays about 1–4% on electronics with a 24 h cookie [CONFLICT on category].

Insurance has consolidated. Thimble (Verifly) no longer offers drone cover [V]. For hobbyists the AMA ($89/yr, $2.5M personal liability) is the default. UK options are FPV UK (£24.99) and BMFA (£51, commercial Open-category cover free from 2026).

Warning: these low-tier firms almost certainly mix military FPV (Ukraine/Russia volumes in the millions of units) with hobby FPV. The 9.03B figure is bigger than the whole consumer drone market in §1.1, which shows the problem. Do not cite it as a hobby-market figure.

Editorial implication: the FCC action applies to critical components, which touches FPV parts (VTX, radios, FCs, motors). A dated, neutral tracker covering what is exempt, what can still be sold and what is proposed, with primary FCC links, is the clearest unmet need (§3.3).

Pilot Institute. Content, courses and a TRUST portal built the largest measured audience in this set (~901k visits/3 mo, US 83%, 6.6-minute visits). It expanded from drones into manned aviation (competitors in Similarweb are boldmethod and ATP), claims 450k+ students, and runs a 20% affiliate program that turns other creators into its sales force. Lesson: free regulatory content feeding paid certification is the most durable model here.

UAV Coach / Drone Pilot Ground School. One flagship course (85k+ students claimed) behind heavy SEO explainers ("DJI Ban", registration). Lesson: regulatory explainers that are updated constantly bring in organic search traffic.

Unusual Machines has since shifted to NDAA-compliant, US-made components for public safety, defense and enterprise, with Rotor Riot as its consumer channel (claimed 30%+ annual growth).

Cross-reference: the O3 Air Unit recorded at 150 Mbps — i.e. the O4 Pro's 130 Mbps is a reduction vs O3, a point worth making explicitly on the site because it is counter-intuitive.
R4-01-technical-gaps.md - 1.1 The "100 vs 130 Mbps" question — resolved [VERIFIED]
Codec [VERIFIED] — DJI's launch announcement states directly: "The O4 Air Unit Series utilizes H.265 video encoding, supporting high-frame-rate transmission at 1080p/100fps". Announcement dated 9 January 2025. So H.265 applies to both the transmission path and (per resellers' spec sheets) recording. No H.264 recording option is documented.

R4-01-technical-gaps.md - 1.1 The "100 vs 130 Mbps" question — resolved [VERIFIED]
Caution for the site: DJI's spec page does not publish a transmission bitrate figure. The 60 Mbps / 50 Mbps live-feed numbers come from reviewers and the Goggles 3 spec sheet, not the O4 spec page. Flag them as [SECONDARY].
R4-01-technical-gaps.md - 1.2 Gyro metadata and Gyroflow [VERIFIED]
DJI's own announcement: RockSteady "is compatible with Gyroflow software for offline post-stabilization" — DJI explicitly endorses Gyroflow for the O4 series. https://www.dji.com/media-center/announcements/dji-o4-air-unit
R4-01-technical-gaps.md - 1.2 Gyro metadata and Gyroflow [VERIFIED]
Gyroflow's README lists DJI "Avata, Avata 2, O3/O4 Air Unit, Action 2/4/5/6/Nano, Neo, Neo2" among cameras with supported embedded gyro metadata (confirmed in R3-04). https://github.com/gyroflow/gyroflow/blob/master/README.md
R4-01-technical-gaps.md - 1.2 Gyro metadata and Gyroflow [VERIFIED]
Conclusion: yes — the O4 and O4 Pro embed usable gyro metadata in the MP4 and Gyroflow reads it natively (no external log). Practical note from the ecosystem: for best Gyroflow results record with in-camera EIS off (or at the lowest setting), since RockSteady already crops and warps the frame — Gyroflow then has a full, un-warped frame to work with. Treat that workflow advice as [SECONDARY] (community practice, not a DJI statement).
R4-01-technical-gaps.md - 1.3 O4 Wide Air Unit [SECONDARY — DJI spec page does not list it]
The O4 Wide exists and ships, sold through DJI's FPV partner channel (Flywoo, GEPRC, etc.). It is not listed on https://www.dji.com/o4-air-unit/specs, which covers only O4 and O4 Pro — so all figures below are reseller spec sheets.

R4-01-technical-gaps.md - 1.3 O4 Wide Air Unit [SECONDARY — DJI spec page does not list it]
"60 Mbps max bitrate" on the Flywoo listing is almost certainly a transcription of the 60 MHz channel bandwidth. GEPRC's sheet gives "Max 60 MHz" bandwidth and no Mbps figure. Do not publish "O4 Wide records at 60 Mbps" — recording bitrate for the O4 Wide is [UNRESOLVED]; its recording mode list is identical to the base O4, which suggests 100 Mbps, but that is inference, not a cited figure.
R4-01-technical-gaps.md - 1.3 O4 Wide Air Unit [SECONDARY — DJI spec page does not list it]
Flywoo sells an "O4 Wide Air Unit Pro" — this is a Flywoo bundle (upgraded antenna, cooling shell, longer coax), not a DJI "Pro" tier. Core transmission/recording is identical to the standard O4 Wide. Do not conflate with the O4 Air Unit Pro.
R4-01-technical-gaps.md - 1.3 O4 Wide Air Unit [SECONDARY — DJI spec page does not list it]
FCC status: [UNRESOLVED]. No FCC ID could be tied to the O4 Wide in this pass. It is sold in the US with a "10 km (FCC)" range figure, which implies FCC authorisation exists under a DJI grantee code (DJI's FCC grantee code is SS3), but the specific FCC ID / grant date was not located. To close: search https://fccid.io/SS3 or the FCC OET Equipment Authorization search for DJI filings dated 2025–2026 and match the model number on the device label.

Important interpretation note: the ~130 ms figure is not comparable to the O4 Pro's 15 ms. The 15 ms number is a goggles-based racing-mode figure (air unit → Goggles 3 display); ~130 ms is a camera-drone latency figure measured to a controller screen (RC 2 / phone-class display pipeline), which includes a much slower display and buffering stage. Never put them in the same column on the site without that caveat.

Three distinct classes of "thrust table" circulate, and they are not interchangeable:
R4-01-technical-gaps.md - 2.0 Method / source-quality note (read before using any of this)
Manufacturer test sheets (T-Motor, iFlight, EMAX, SunnySky). Published as JPEG/PNG images embedded in product pages, so they are not machine-transcribable and could not be read wholesale in this pass. Manufacturers also test with a fixed bench supply at a rounded voltage (typically 24.0 V for "6S", 16.0 V for "4S") rather than a sagging LiPo, and often on a prop of their choosing — these numbers are systematically optimistic vs. in-flight.

Mini Quad Test Bench (MQTB) — the best independent dataset for 5" motors, with a documented rig (load cell + RPM + V/I logged at 4 ms intervals, XRotor 40 A ESC, bench supply). Its HTML pages carry only a summary; the numeric tables live behind assets/components/motordata/motorinfo.php?uid=NNN. Coverage is essentially 2017–2020, so it has no 1404-class, 2806.5-class or 2025–26 motors. Base URL pattern: https://www.miniquadtestbench.com/assets/components/motordata/motorinfo.php?uid=

R4-01-technical-gaps.md - 2.0 Method / source-quality note (read before using any of this)
Transcription caveat found this session: on some MQTB motorinfo.php pages the automated extraction returned an implausible current column (e.g. 165–190 A on a 5" 2207). Where that happened I have derived current as P ÷ V from the page's own power and voltage columns and marked it (derived). Where the page's own current column was self-consistent with P/V it is quoted as-is. Anyone publishing these numbers should re-read the source page by eye.

The "2,098 g at 46 A on 6S" figure is a headline/summary number, not a table row. The highest row in the actual MQTB dataset is 2,053 g at 46.4 A. Treat 2,098 g as the article's peak-sample claim and 2,053 g as the citable measured figure.

Rule of thumb that the verified data does support (safe to publish): a good 5" 2207 on 6S at 100 % throttle lands at 1,700–2,100 g of thrust, 32–47 A, 750–1,080 W, and 1.8–2.3 g/W; efficiency falls monotonically as you move to higher-pitch props, and the highest-thrust prop is never the most efficient one. On 4S the same class gives 1,300–1,600 g at 2.1–2.5 g/W — better efficiency, much lower ceiling.
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
Almost all published FPV latency numbers are incomparable because they use different conventions. Three exist:
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
Convention — What it measures — Effect on the number
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
First-pixel — camera exposure → first row of that frame appears on the goggle display — lowest figure
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
Half-frame — → middle of the frame appears — +½ frame period; the convention pilots' reaction actually tracks
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
Full-frame — → last row appears — highest; +1 full frame period
R4-01-technical-gaps.md - 3.0 The measurement-convention trap (state this before any number)
At 60 fps a frame period is 16.7 ms, so the same system can be quoted as 11 ms or 28 ms depending only on convention. Any site table must name the convention in the column header. Vendor figures (DJI's "15 ms", HDZero's "<3 ms") are neither — they are internal encode/RF-pipeline figures that exclude camera sensor readout and display scan-out.

R4-01-technical-gaps.md - 3.1 The best independent 2026 dataset found [SECONDARY]
Method: a quad's camera is pointed at a monitor running a latency-tester pattern; a slow-motion camera films the monitor and the goggle screen in one frame; delay is counted in recorded frames. The author validates that the slow-mo camera really captures at its advertised fps by timing a known test cycle. Metric is half-frame latency, chosen because it "matches how pilots react during maneuvers".

Key qualitative finding worth quoting: "the recording mode selected in DJI O3 directly affects the latency and the frame rates available" — i.e. turning on high-bitrate/high-res DVR changes live-feed latency on DJI air units. This is a real, under-reported gotcha.

R4-01-technical-gaps.md - 3.3 Instrumented (non-camera) method — the gold standard [VERIFIED method]
Brushless Whoop, "Measuring FPV Latency", 4 April 2020. Photodiode/LED + Arduino rather than a slow-motion camera:
R4-01-technical-gaps.md - 3.3 Instrumented (non-camera) method — the gold standard [VERIFIED method]
5 V LED (270 Ω series) taped to the FPV camera lens; photoresistor (10 kΩ pull-down) taped to the goggle/monitor screen; Arduino Uno (16 MHz) times LED-on → photoresistor threshold crossing, in microseconds.
R4-01-technical-gaps.md - 3.3 Instrumented (non-camera) method — the gold standard [VERIFIED method]
Instrument baseline (LED + photoresistor with no video link in between): ~113 µs — i.e. the rig contributes <0.2 ms, negligible.
R4-01-technical-gaps.md - 3.3 Instrumented (non-camera) method — the gold standard [VERIFIED method]
This yields true glass-to-glass latency including "Camera, VTX, VRX and screen".
R4-01-technical-gaps.md - 3.3 Instrumented (non-camera) method — the gold standard [VERIFIED method]
Representative analog result: mean 10.9 ms, range 4–18 ms over 10 samples — note the ~14 ms spread, which is exactly one frame period of jitter; this is why single-number latency claims are misleading and n≥20 with min/mean/max is mandatory.

R4-01-technical-gaps.md - 3.6 HDZero — what its compression actually is [VERIFIED for JSCC; vendor wording flagged]
HDZero's own marketing claims are not a technical description. hd-zero.com/technology states only: "glass to glass latency < 3 ms", broadcasts "uncompressed video streams" with "less than 1 ms fixed latency", LOS up to 7.3 km. Those figures are for the encode+RF stage, not true glass-to-glass (measured G2G is ~11 ms half-frame per §3.1).

R4-01-technical-gaps.md - 3.6 HDZero — what its compression actually is [VERIFIED for JSCC; vendor wording flagged]
Scheme: Joint Source Channel Coding (JSCC) — source coding and channel coding are designed together as one mapping from pixels to RF symbols, rather than "compress to a bitstream, then protect the bitstream with FEC" as H.264/H.265 systems do. Because there is no frame buffer and no inter-frame prediction, latency is fixed and sub-frame, and degradation is graceful (progressive softening, analog-like) rather than the block-freeze/stutter of a predictive codec losing a reference frame. Stated capability: up to 1080p30 transmitted this way; HDZero product modes in practice are 720p60 / 540p90 (and 720p90 on the Goggle 2 chain).

Behaviourally it is "a one-way 'stream' of video" resembling analog, not a bidirectional negotiated link.
R4-01-technical-gaps.md - 3.6 HDZero — what its compression actually is [VERIFIED for JSCC; vendor wording flagged]
Wording guidance for the site: do not write "HDZero is uncompressed" as a factual claim, and do not write "HDZero uses no compression". JSCC is a source-coding step — it just isn't a predictive, buffered, variable-bitrate codec. The defensible phrasing is: "HDZero uses Joint Source Channel Coding on a Divimath DM5680 — a fixed-rate, intra-frame-only scheme with no frame buffer and no inter-frame prediction, which is why its latency is fixed and sub-frame and its failure mode is analog-like. HDZero markets this as 'uncompressed'." Attribute "uncompressed" as a vendor claim, in quotes.

R4-01-technical-gaps.md - 4.1 Semi-solid / silicon-anode packs for hobby drones in 2026 — the answer is no [VERIFIED]
Publishable conclusion: "Semi-solid-state and silicon-carbon-anode cells are real and shipping — at 280–500 Wh/kg — but only in 16–99 Ah, 4S–24S commercial UAV packs where nobody publishes a C-rating. Nothing in the hobby/FPV market uses them as of late 2026, because FPV needs 100C+ pulse capability that these chemistries do not advertise. The best hobby packs remain conventional LiPo (Tattu R-Line V6.0 class, up to 160C)." That framing is defensible from the vendors' own pages.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
The core problem [SECONDARY, well-sourced]: hobby chargers use one of two fundamentally different techniques and they do not agree.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Method — How it works — Bias
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
AC conductance / "frequency method" (most chargers, incl. cheaper units) — injects a small AC signal (typically ~1 kHz) and measures impedance magnitude — always reads LOWER than DC load, because at 1 kHz the double-layer capacitance shunts part of the cell's charge-transfer resistance
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
DC load / pulse method (higher-end chargers, proper IR meters) — applies a known current step and measures the voltage drop; R = ΔV / ΔI — reads higher; closer to what the cell actually does under a throttle punch
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Never compare IR numbers from two different chargers. Different chargers give different readings for the same pack. Pick one charger and track that charger's numbers over the pack's life.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Record a baseline when the pack is brand new, then track the trend. The delta is meaningful; the absolute value is not.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Temperature dominates. Warm packs read artificially low (ion mobility rises with temperature). Measure at a consistent ~22 °C / 72 °F.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
State of charge matters less than people think — one source finds SoC "doesn't cause much variation" and recommends 50 % / 3.85 V per cell after resting; another recommends full charge (4.20 V/cell). These two recommendations conflict. The reconcilable rule is: always measure at the same SoC, whichever you pick.
R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Balance leads and connectors are part of the measurement. At the single-milliohm level, a corroded balance connector or a poorly crimped XT60 shows up as "cell degradation" that isn't.

R4-01-technical-gaps.md - 4.2 LiPo internal-resistance measurement: charger readings vs. proper measurement [SECONDARY, converging sources]
Critical caveat to publish alongside the table: IR scales roughly inversely with cell capacity and electrode area, so a 150 mΩ 150 mAh whoop cell and a 3 mΩ 6,000 mAh cell can be equally healthy. Absolute mΩ thresholds are only meaningful within one capacity class. A capacity-normalised figure (mΩ × Ah, or equivalently the cell's I²R loss at its rated current) is the honest comparison, and almost nobody publishes it.

[UNRESOLVED]: no controlled side-by-side study was found that measures the same packs with (a) several popular chargers' built-in IR functions and (b) a laboratory pulse/DC-load or EIS rig, and publishes the discrepancy in mΩ or percent. That comparison appears not to exist in public. If the site wants it, it is a genuinely original and cheap experiment: one pack, five chargers, plus a DC-load step at a known current, reported as a table.

No count could be obtained, and this is a structural obstacle, not a rate limit. uasdoc.faa.gov/listDocs is a JavaScript single-page application: the static HTML served to any non-browser client is only the string "You need to enable JavaScript to run this app." Direct attempts against the site's JSON API (/api/v1/docs) were blocked at the network layer in this environment (proxy CONNECT tunnel failed, response 403).

Secondary sources do not fill the gap: the most-cited legal summary of Part 89 (Rupprecht Law, https://jrupprechtlaw.com/remote-identification/) links the FAA list and explains how to search it but publishes no total, and its most recent substantive content is the September 2023 enforcement-discretion statement.

Compliance and Enforcement Bulletin No. 2026-1 (Feb 2026) reverses the FAA's default posture from "compliance conversation / education" to legal action by default. Three triggers route a case straight to the FAA Chief Counsel for enforcement:

An inspector now has to justify not pursuing legal action, rather than justify pursuing it.
R4-01-technical-gaps.md - 5.3 Remote ID enforcement — resolved, and more significant than expected [VERIFIED/SECONDARY]
Remote ID is named explicitly: operating without Remote ID in violation of 14 CFR § 89.105 is listed as a violation of "established airspace restrictions" — i.e. it is a category-2 trigger and therefore now a default-legal-action item. This is the single most important Remote ID regulatory fact of 2026 for a hobby audience.

Important honesty caveat: none of the named, dollar-figure cases above is a Remote ID case. They are airspace, over-people and emergency-response cases. [UNRESOLVED]: no publicly reported civil penalty whose cited violation is Part 89 / Remote ID could be found. So the accurate statement for the site is:
R4-01-technical-gaps.md - 5.3 Remote ID enforcement — resolved, and more significant than expected [VERIFIED/SECONDARY]
"Remote ID became enforceable on 16 March 2024, and since Compliance and Enforcement Bulletin 2026-1 (February 2026) flying without Remote ID is treated as an airspace violation that triggers legal action by default rather than a warning. That said, every publicly reported FAA drone civil penalty to date has been for airspace, over-people or emergency-response violations — no published penalty names Part 89 Remote ID as the violation. Remote ID's practical role so far has been as the tool that identifies the operator in those other cases, not as the charge itself."

R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
R3-04 established the source-verified ELRS packet intervals and time-on-air from ExpressLRSAirRateConfig[] / ExpressLRSAirRateRFperf[] at tag 4.1.0. Those two numbers set a hard lower bound on link latency that no implementation can beat:
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
mean link latency ≳ ½ × packet interval + time-on-air
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
(½ × interval is the average wait for the next transmit slot for a stick movement arriving at a random time; ToA is the transmission itself. On top of this sit the handset's mixer period, the CRSF UART frame time, and the FC's own RX-processing and PID-loop scheduling.)

R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
Three things this table makes clear, and which the site should say:
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
The "5 ms" ELRS claim is consistent with 250 Hz LoRa, not with 500 Hz. At 500 Hz LoRa the floor is ~2.5 ms and at F500/F1000 it is ~1–1.4 ms. ELRS's claim is conservative.
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
Crossfire's measured 13.9 ms is exactly what a 900 MHz LoRa link at ~150 Hz should give (compare ELRS 900 MHz 100 Hz: ~13.8 ms floor). The number is not a defect — it is LoRa physics at 900 MHz, where long time-on-air is the price of the sensitivity that buys the range. Tracer is faster than Crossfire because it is 2.4 GHz with a shorter ToA, not because TBS wrote better firmware.
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
The interesting comparison is not latency, it is latency stability. Tracer holds 250 Hz regardless of RSSI; Crossfire drops 150 Hz → 50 Hz as signal degrades, so its latency roughly triples at range (~14 ms → ~40+ ms) exactly when you need it least. ELRS behaves like Tracer here — the rate is user-selected and fixed, it does not fall back.
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
Also source-verified in R3-04: ELRS RX sensitivity spans −101 dBm (900 MHz GFSK K1000) to −123 dBm (900 MHz 25 Hz); ELRS docs recommend an RSSI warning threshold 5–10 dB above the mode's sensitivity limit (https://github.com/ExpressLRS/Docs/blob/master/docs/info/signal-health.md).
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
TBS Tracer other specs [SECONDARY]: 2.4 GHz ISM, 25 mW / 100 mW selectable, "25 km (15 miles) on 100 mW" (TBS claim). Crossfire: 900 MHz LoRa, "100 km" per TBS's own testing.
R4-01-technical-gaps.md - 6.2 What can be stated rigorously — the physics floor, from ELRS source
To close item 6 properly, the cheap experiment is: CRSF-sniff a UART line at the FC while toggling a stick with a switch that also triggers a scope channel, and read the delay to the first changed channel value — or use the same Arduino LED/photodiode trick from §3.3 with an LED driven from a motor output. Nobody appears to have published this.

What transfers: the CT / CP / η framework, the static thrust and power coefficients, and — most importantly — the Reynolds-number sensitivity result: small props operate at Re ≈ 25,000–100,000 where performance degrades sharply and non-linearly with falling Re. This is the correct theoretical basis for why a 3" prop is not a scaled-down 5" prop, and why small props are inherently less efficient.

What does not transfer: the database is dominated by fixed-wing / slow-fly propellers of 9–18"+ with 2 blades. There is essentially no coverage of 5" 3-blade FPV props, no high-pitch racing props, and no 4S/6S FPV RPM range (FPV 5" props run 25,000–37,000 RPM; UIUC test RPMs are an order of magnitude lower). Do not use UIUC data to predict FPV prop thrust.

14 — Remote ID enforcement — RESOLVED [VERIFIED/SECONDARY] — enforceable from 16 Mar 2024 (FAA newsroom, 15 Mar 2024, ends the Sep 2023 discretion policy). FAA Compliance and Enforcement Bulletin No. 2026-1 (Feb 2026) makes legal action the default and explicitly names 14 CFR § 89.105 (no Remote ID) as an airspace-restriction violation triggering it. FAA 2023–2025: 18 civil penalties, $1,771–$36,770; 8 certificate actions in 2025; statutory max $75,000/violation. Caveat: no published penalty names Part 89 as the violation — all named cases are airspace/over-people/emergency-response.

15.2 — Crossfire / Tracer / ELRS latency — PARTIAL — Tracer 3 ms @ 250 Hz constant (vendor); Crossfire 13.9 ms @ 50–150 Hz dynamic (third-party measured, method unpublished); ELRS "as low as 5 ms" (project claim). Resolved instead with a source-verified physics floor (½ × packet interval + time-on-air) computed for all 13 ELRS modes from ELRS 4.1.0 source — which explains Crossfire's 13.9 ms as 900 MHz LoRa ToA, not bad firmware. No instrumented three-way comparison exists [UNRESOLVED].

Relevance limit stated: 9–18" 2-blade fixed-wing props at 1,000–10,000 RPM, Re 25k–100k — does not cover 5" 3-blade FPV props at 25k–37k RPM. Key multirotor paper: Deters/Kleinke/Selig AIAA 2017-3743 (10 prop pairs, 9–12", static pendulum balance, A/lb + hover endurance; best-to-worst prop spread only 5.44 % endurance). APC PER3 = computed (vortex theory), not measured — APC publishes no accuracy band and points to UIUC for empirical data. Tyto Robotics community DB: 121 motors / 191 props / 55 ESCs / 1,518 systems / 174,811 samples, free, community-uploaded — FPV-class coverage unconfirmed.

R4-01-technical-gaps.md - Note on source quality encountered
A large volume of 2026-dated search results for these exact queries come from a single SEO content farm (blog.uavmodel.com) which publishes many near-duplicate articles restating vendor claims as if measured. None of its numbers are used in this report. The figures above come from: DJI's own spec/announcement pages, HDZero's own technology page, Grepow/Tattu/iFlight/SunnySky product pages, the FAA newsroom and eCFR, Mini Quad Test Bench raw data endpoints, UIUC/AIAA papers, APC's own page, ExpressLRS source code, and named reviewer benches (Unmanned Tech, Oscar Liang, Mads Tech Wiki, Brushless Whoop, Recursion Labs, AOS Labs, Heliguy, DroneXL, DroneDJ, Autonomy Global).
R4-01-technical-gaps.md - R4-02 — Database Verification Pass (Round 4)
Verification run 2026-09-17. Targets: data/drone-models.csv (86 rows, 18 cols) and data/fpv-gear.csv (now 57 rows, 8 cols).
R4-02-database-verification.md - R4-02 — Database Verification Pass (Round 4)
Scope: rows tagged unverified or secondary, plus the eight named open questions carried over from R3-02-consumer-fpv-catalog.md §8.
R4-02-database-verification.md - R4-02 — Database Verification Pass (Round 4)
Header order and column count of both files are unchanged. No rows were deleted. One row was added to fpv-gear.csv (HDZero Gamma 45A AIO), because it is the 2026 HDZero hardware release the open-questions list was asking about.
R4-02-database-verification.md - R4-02 — Database Verification Pass (Round 4)
Totals: 233 individual field changes across 45 rows. Every unverified row in both files is now resolved to verified or secondary.
R4-02-database-verification.md - 1.1 DJI Avata 360 EU class mark — RESOLVED: C1
Heliguy's class-mark knowledge base states the Avata 360 "is marked as a UK1 drone. It also has an EU-C1 class mark." This is consistent with the 455 g airframe and with Avata 2 (377 g) also being C1.
R4-02-database-verification.md - 1.1 DJI Avata 360 EU class mark — RESOLVED: C1
euclass: (blank) → C1 (UK1 in the UK)
R4-02-database-verification.md - 1.1 DJI Avata 360 EU class mark — RESOLVED: C1
sourceurl: dronedj.com price article → https://www.heliguy.com/blogs/knowledge-base/does-the-dji-avata-360-have-a-uk-drone-class-mark/
R4-02-database-verification.md - 1.1 DJI Avata 360 EU class mark — RESOLVED: C1
Confidence held at secondary: the statement is from a major retailer's knowledge base, not from DJI's own EU spec page or the EASA list. One more independent confirmation would justify verified.
R4-02-database-verification.md - 1.2 Antigravity A1 class mark — RESOLVED: C0 standard / C1 high-capacity
The manufacturer spec page gives both class marks explicitly, and also corrects the range figures, which were wrong in the CSV.
R4-02-database-verification.md - 1.2 Antigravity A1 class mark — RESOLVED: C0 standard / C1 high-capacity
euclass: C0 (standard battery; high-cap not sold in EU) → C0 with standard battery (249 g); C1 with high-capacity battery (291 g)
R4-02-database-verification.md - 1.2 Antigravity A1 class mark — RESOLVED: C0 standard / C1 high-capacity
rangekmclaimed: 10 (FCC); 6 (CE) → 13 (std battery); 23 (high-cap battery) — the old figures were materially wrong
R4-02-database-verification.md - 1.2 Antigravity A1 class mark — RESOLVED: C0 standard / C1 high-capacity
obstaclesensing: generic "360 vision sensing" → forward vision 0.5–18 m / 93° H, downward 0.3–7.5 m, bottom infrared
R4-02-database-verification.md - 1.2 Antigravity A1 class mark — RESOLVED: C0 standard / C1 high-capacity
Confidence: secondary → verified (manufacturer page). Note the R3-02 claim that the high-capacity battery is "not sold in the EU" is contradicted: Antigravity publishes an EU C1 mark for it.
R4-02-database-verification.md - 1.3 Lito X1 C0 vs C1 by battery — RESOLVED
Standard battery: ~249 g takeoff weight, C0, no exam needed for A1.
R4-02-database-verification.md - 1.3 Lito X1 C0 vs C1 by battery — RESOLVED
Intelligent Flight Battery Plus: raises MTOW to ~340 g and the aircraft is C1-marked; sold only in the Fly More Combo Plus, and the A1/A3 online exam becomes mandatory. Heliguy independently confirms the Plus battery "is only compliant for use with the aircraft from the DJI Lito X1 Fly More Combo Plus."
R4-02-database-verification.md - 1.3 Lito X1 C0 vs C1 by battery — RESOLVED
This also explains the "340 g" figure that DroneCompare had been mis-labelling as aircraft weight (R3-02 §7 flag 1): 340 g is the Plus-battery MTOW.
R4-02-database-verification.md - 1.3 Lito X1 C0 vs C1 by battery — RESOLVED
euclass: C0 (dronecompare also lists C1) → full battery-conditional string; flighttimeminclaimed: 36 → 36 (52 w/ Battery Plus)
R4-02-database-verification.md - 1.3 Lito X1 C0 vs C1 by battery — RESOLVED
Confidence: secondary → verified.
R4-02-database-verification.md - 1.4 DJI Mini 5 Pro Battery Plus Wh — RESOLVED
4,680 mAh / 33.51 Wh / 7.16 V nominal (8.6 V max charge), $145, 52 min claim. Recorded in usstatussep2026 alongside the already-known standard battery (2,788 mAh / 19.52 Wh / 7.0 V).

R4-02-database-verification.md - 1.5 CoDrone EDU Plus specs/price — PARTIALLY RESOLVED, price genuinely does not exist yet
Robolink's own product page confirms dual front- and downward-facing cameras with a physical privacy cover and computer-vision object detection plus colour recognition. On price it says outright: "we cannot share final pricing yet." Drones are "in production and will ship during the 2026-27 school year"; pre-orders are not open.
R4-02-database-verification.md - 1.5 CoDrone EDU Plus specs/price — PARTIALLY RESOLVED, price genuinely does not exist yet
Weight, flight time and price remain unpublished — held at secondary. This is not a research gap; the vendor has not released the numbers.
R4-02-database-verification.md - 1.5b Bonus resolution — CoDrone EDU (base model) country of origin
The original CoDrone EDU row carried "manufacturing location unverified," which mattered for the Buy American / FCC toy-exemption question in R3-01. Robolink's spec table states "Made in China." Also captured: 54.8 g, 7–8 min flight, 7 sensors, no camera, $249 single / $3,599 (12-pack) / $5,399 (18-pack).
R4-02-database-verification.md - 1.5b Bonus resolution — CoDrone EDU (base model) country of origin
Confidence: unverified → verified. Practical consequence now recorded in the row: a US brand, but not a US-made drone.
R4-02-database-verification.md - 1.6 RadioMaster GX15 price — RESOLVED
$199.99 (GX15) / $269.99 (GX15 MAX). Full specs captured: 3.5in IPS 480×320 touchscreen at 600 nits, STM32H7, dual SX1281 250 mW ELRS 2.4 GHz (Gemini, F1000), V6 Hall gimbals on the standard and AG02 CNC on the MAX, 725 g (MAX, no battery), EdgeTX 2.12+.
R4-02-database-verification.md - 1.6 RadioMaster GX15 price — RESOLVED
Note: R3-02 described the GX15 as having "AG02 gimbals" generally — that is MAX-only; the standard GX15 ships V6 Hall.
R4-02-database-verification.md - 1.7 2026 HDZero and Walksnail hardware — RESOLVED
HDZero — the current NEW items on HDZero's own shop are the Gamma 45A HD-Ready AIO ($79.99 direct, $89.99 GetFPV street) and the Eco VTX (out of stock). The Gamma was added to fpv-gear.csv as a new fcesc row (STM32G473 FC + 4-in-1 AM32 45 A/60 A burst ESC + built-in ELRS 2.4 GHz RX, 25.5×25.5 mm, dual BEC 8 V/3 A + 5 V/3 A, 3–6S, 8.4 g). There is no new HDZero goggle in 2026; Goggle 2 remains current.
R4-02-database-verification.md - 1.7 2026 HDZero and Walksnail hardware — RESOLVED
The Goggles 2 row also carried wrong specs: it was recorded as "720p60/540p90, 10–20 ms latency." HDZero's own page gives 1920×1080 @ 90 fps OLED and 3 ms glass-to-glass, 46° FOV, $699.99. Corrected; secondary → verified.
R4-02-database-verification.md - 1.7 2026 HDZero and Walksnail hardware — RESOLVED
Walksnail — current lineup is Avatar Goggles X / Goggles L, and the Moonlight (4K camera + 1 W VTX, 32/64 GB onboard) and GT / GT2 (1080p100 global-shutter racing) camera+VTX kits, plus the Ascent budget line. Goggles X is $829; the Ascent Goggles + Lite VTX bundle is $184.99. No single product could be pinned to a specific 2026 launch month from available sources — see §4.
R4-02-database-verification.md - 1.7 2026 HDZero and Walksnail hardware — RESOLVED
Goggles X: secondary → verified (1080p/100 fps H.265, 50° FOV, 290 g, HDMI in/out, replaceable lenses).
R4-02-database-verification.md - 1.7 2026 HDZero and Walksnail hardware — RESOLVED
Ascent: priceusd 149 → 184.99 for the goggles+VTX bundle; secondary → verified.
R4-02-database-verification.md - 1.8 Does the DJI O4 Wide have its own FCC ID? — RESOLVED AS "NO SEPARATE GRANT FOUND"
Two independent negative checks: (a) SZ DJI's FCC ID index shows grants only for SS3-DF3L290424 (O4 Air Unit) and SS3-DF3P290424 (O4 Air Unit Pro) — no O4 Wide entry; (b) DJI's own o4-air-unit/specs page still lists only the O4 and O4 Pro and does not list the Wide at all. Combined with Oscar Liang's finding that the Wide reuses the O4 Lite's sensor, gyro (1469D / ICM-40609-D) and overall hardware, the Wide appears to ship under the pre-cutoff O4 Lite grant. Recorded as such, explicitly flagged unconfirmed. Row held at verified for its hardware specs; the FCC inference is worded as an inference.
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
Both figures are correct and describe different modes:
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
4K240 — 16:9, 8× slow motion, PRO only.
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
4K120 open gate — full 4:3 sensor readout, available on both MISSION 1 and PRO.
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
PetaPixel was quoting the open-gate figure; GoPro's press release was quoting the 16:9 figure. Full PRO ladder now recorded: 8K60 (16:9), 4K240 (16:9), 8K30 + 4K120 open gate, 1080p960 in 10 s bursts / 1080p480 continuous.
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
MISSION 1 PRO: secondary → verified. MISSION 1 also corrected (8K30, 4K120, 4K120 open gate, 1080p240, no 4K240) and secondary → verified.
R4-02-database-verification.md - 1.9 GoPro MISSION 1 PRO 4K240 vs 4K120 — RESOLVED: not a conflict, a mode difference
The R3-02 §7 flag 6 "FLAG: GoPro press release says 4K240 while PetaPixel reports 4K120" can be struck.
R4-02-database-verification.md - 2. Budget-brand consumer rows — key corrections
All eight named brands were checked. Note: there are no Snaptain or Syma rows in drone-models.csv — consistent with R3-02's finding that no 2025–26 camera drone was found from either brand, so there was nothing to verify.

R4-02-database-verification.md - 2. Budget-brand consumer rows — key corrections
Holy Stone HS900 PRO — Flight time 60 (claimed) → ~30 per battery (60 total with the 2 included batteries) — the headline "60 min" is a two-battery total, not an endurance figure. Weight 249 g, Sony 48MP, 4K/30 H.265, 10 km, no obstacle avoidance, $389.99 but SOLD OUT on Holy Stone's US store 2026-09-17. unverified → verified

Holy Stone T60A — Same two-battery pattern made explicit: 45 → 45 per battery (90 total with 2 batteries, windless). 1/2in Sony CMOS, 4K HDR, 10 km, positioning-only sensing (optical flow + ToF, no avoidance). $499.99 street (list $559.99), SOLD OUT. Aircraft weight still not published by Holy Stone → held secondary
R4-02-database-verification.md - 2. Budget-brand consumer rows — key corrections
Holy Stone HS720G — Weight filled in at 377 g (so FAA registration required — this is not a sub-250 g drone). Range filled in: 999 m control / 500 m FPV, i.e. ~1 km, far below other Holy Stone claims. Obstacle sensing "None" confirmed by Holy Stone's own FAQ. unverified → verified
R4-02-database-verification.md - 2. Budget-brand consumer rows — key corrections
Holy Stone HS360S — Weight 249 g and 3 km / 3 km confirmed on Holy Stone's page — the "10,000 ft" Amazon figure is ~3 km, so the two are consistent, not contradictory. Holy Stone publishes no price, fps or flight time. Amazon blocks automated fetching, so price unconfirmed → unverified → secondary

Jumper T15 Pro — existence confirmed (it is a distinct product from the plain Jumper T15, which sells for $207.99 at GetFPV). No US retailer listing could be found; Oscar Liang puts it at roughly $200–300 by version (FPG ~$300). A notable finding was captured: despite dual-band marketing, the internal RF is 2.4 GHz only — no internal 900 MHz or Gemini, unlike the RadioMaster TX15 it competes with. Held secondary because the price is a reviewer estimate, not a retail listing.

Antigravity A1 range was wrong in the CSV (10 km FCC / 6 km CE → actually 13 km standard / 23 km high-capacity), and the high-capacity battery does carry an EU C1 mark, contradicting "not sold in the EU."
R4-02-database-verification.md - 6. Corrections that should propagate to R3-02 and the site
The "340 g" Lito figure is the Plus-battery MTOW, not a DroneCompare error about aircraft weight. R3-02 §7 flag 1 should be narrowed accordingly — DroneCompare's other errors stand.

Budget-brand flight-time claims are two-battery totals. HS900 PRO's "60 min" and T60A's "90 min" are sums across two packs; Ruko and Bwine do the same. Any buyer-facing table should show per-battery endurance.

R4-02-database-verification.md - 7. Process note
military-platforms.csv was inadvertently re-written once during this session: a filename collision in the shared scratchpad caused a leftover Round-3 edit script to execute. That script only re-assigns fixed values to seven named rows, so the operation was idempotent. The file was re-validated afterwards — 53 rows, 14 columns, well-formed, header intact — and is unchanged in substance. All four CSVs in data/ were parse-checked at the end of this pass: drone-models.csv 87 lines/18 cols, fpv-gear.csv 58 lines/8 cols, military-platforms.csv 53 rows/14 cols, adjacent-platforms.csv 76 rows/13 cols.

India's drone Bill is still only a draft — dated 2025-09-16, consultation closed 2025-09-30, never introduced in Parliament. Drone Rules 2021 (nano/micro, NPNT, Digital Sky) remain the operative law.
R4-03-regulatory-business-gaps.md - 0. Headline findings
No 2025–26 rule change found for recreational flyers in Australia or Japan. Australia: sub-250 g recreational needs no registration, accreditation or licence. Japan: registration at 100 g+ with Remote ID; the real 2025–26 event is the expiry of the pre-registration grandfathering (from 2025-06-20), which forces Remote ID on renewal.

R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
Finding: NO — a drone flight battery is a spare/loose lithium battery, not a power bank, even if it has a USB-A/USB-C output port. But the reasoning is inferential, not an explicit ruling.
R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
The ICAO/IATA definition turns on the article being a "universal external power source… capable of providing power to multiple devices such as mobile phones." A DJI Intelligent Flight Battery is a proprietary pack whose purpose is powering one specific aircraft; its USB port is a secondary convenience feature, not the article's function. [VERIFIED definition; interpretation is ours]
R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
The IATA operator guidance does not mention drone batteries at all and explicitly frames power banks as external chargers for phones/laptops/cameras. [VERIFIED-absence] same PDF
R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
Therefore the governing limits for drone packs remain the spare lithium-ion battery rules: ≤100 Wh unlimited (subject to reasonable quantity), 101–160 Wh with airline approval, max 2, >160 Wh forbidden on passenger aircraft, carry-on only, terminals protected.
R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
Practical risk for hobbyists: several carriers' 2025–26 power-bank notices are written broadly ("any device that can charge another device"), and DJI's own Mini/Air/Mavic two-way charging hubs and the DJI Power series are power banks. Cabin crew apply the count/no-charging rules by appearance. Editorially, tell readers: carry drone packs in the cabin, in LiPo bags, discharged to storage level, and do not use a flight battery to charge a phone in flight.
R4-03-regulatory-business-gaps.md - 4.2 Do drone batteries with USB output count as power banks?
[UNRESOLVED] No explicit ICAO, IATA, FAA or EASA statement classifying drone batteries with USB output. Searched IATA guidance, FAA PackSafe. If the site publishes this, flag it as interpretation.
R4-03-regulatory-business-gaps.md - 4.3 FAA PackSafe wording (page last updated 2026-08-11)
Carried forward from R3-01 as [VERIFIED]: spare batteries and power banks carry-on only (must be removed from gate-checked bags); ≤100 Wh permitted; 101–160 Wh with airline approval, limit 2 spares; >160 Wh forbidden; terminals must be protected against short circuit; airlines may impose stricter power-bank limits. https://www.faa.gov/hazmat/packsafe/lithium-batteries
R4-03-regulatory-business-gaps.md - 4.3 FAA PackSafe wording (page last updated 2026-08-11)
The FAA's dedicated drones PackSafe page is stale (last updated 2024-01-24) and simply points to the "Your Drone Might Be a Dangerous Good" brochure. https://www.faa.gov/hazmat/packsafe/drones — i.e. the FAA has not updated its drone-specific battery guidance for the 2026 ICAO power-bank change.

Why this matters for an FPV site: the 9,000-pulses-per-second test catches essentially every FPV flight controller, ESC, VTX, receiver and camera DSP. From 2026-10-13 a builder-oriented retailer cannot obtain a new FCC authorization for a product containing a Covered List entity's logic-bearing part; existing authorizations survive. From 2027-03-01/06-01 Amazon, AliExpress, eBay and Banggood-type marketplaces must surface FCC IDs at the point of sale, which will visibly cull unauthorized FPV parts listings. That is a concrete, dateable editorial hook.

Practical estimate: a Chinese-origin consumer camera drone ≤25 kg without thermal faces roughly 0% MFN + 25% legacy 301 + 25% §232 ≈ 50% in 2026. A Chinese thermal drone faces ~0% + 25% + 100% ≈ 125%. The widely repeated "~170%" figure is a stale April-2025 number built from 25% (301) + 125% (the since-invalidated IEEPA reciprocal tariff) and must not be reused.

R4-03-regulatory-business-gaps.md - 6.4 [UNRESOLVED] — the exact legacy Section 301 line for HTS 8806
Still not pinned to a primary source. Reasons and what to do:
R4-03-regulatory-business-gaps.md - 6.4 [UNRESOLVED] — the exact legacy Section 301 line for HTS 8806
HTS heading 8806 was created by HS 2022. USTR's 2018–19 List 1/2/3/4A annexes were written against the pre-2022 nomenclature (drones were classified under 8802.11.00 as other aircraft and, for camera drones, 8525.80.30 "television cameras," which sat on List 1 at 25%). The 25% figure in trade press is almost certainly inherited from those codes.
R4-03-regulatory-business-gaps.md - 6.4 [UNRESOLVED] — the exact legacy Section 301 line for HTS 8806
The authoritative answer is the footnote / Chapter 99 cross-reference in the USITC HTS for each 8806 subheading (look for a subheading in the 9903.88 range). Neither hts.usitc.gov (proxy 403) nor the commercial tariff databases (paywalled or code-level-only) could be read this round: ustariffrates.com says "25,321 HTS codes currently subject to Section 301" but will not itemise; Greenwich Mercantile explicitly defers to the USITC footnotes; Flexport shows MFN only.
R4-03-regulatory-business-gaps.md - 6.4 [UNRESOLVED] — the exact legacy Section 301 line for HTS 8806
Action before publishing any cumulative rate: look up 8806.21.00 / 8806.22.00 / 8806.24.00 / 8806.29.00 / 8806.91–99 at https://hts.usitc.gov and record the 9903.88.xx footnote and rate, plus the 9903 code for the new §232 UAS duty. Also check CBP CSMS #69738151 (2026-09-02) for the §232 filing instructions.

R4-03-regulatory-business-gaps.md - 7.2 Explanation of the apparent drop
There was no drop. Three different things are being counted, and the web page is out of date.
R4-03-regulatory-business-gaps.md - 7.2 Explanation of the apparent drop
"400,000+" in 2024 and 493,396 at Dec 2025 are the same series — cumulative remote pilot certificates issued. The Forecast states the method: "we take pilots who passed the initial knowledge test (or Part 107), plus current traditional pilots who took online training in lieu of the knowledge test (or Part 61)." That is cumulative, not current-and-valid. Of the 493,396: 78% hold only a Part 107 certificate; 22% also hold a Part 61 pilot certificate. [VERIFIED]
R4-03-regulatory-business-gaps.md - 7.2 Explanation of the apparent drop
"223,634" on the By the Numbers page is a stale snapshot, not a redefinition to "current certificates." It is roughly the level the FAA reported in 2021–22. The R3-06 hypothesis that the FAA switched to counting current certificates is not supported — the Forecast, published later, still reports cumulative and reports a much larger number. Correct R3-06 §2.1 accordingly.
R4-03-regulatory-business-gaps.md - 7.2 Explanation of the apparent drop
Registered-drone counts also differ by definition: Part 48 recreational registration is one registration per flyer (covering all their aircraft), so "502,105 recreational" on the web page is flyers-ish, while the Forecast's 1.59M is an aircraft estimate. They are not comparable. Commercial registration is per aircraft, so 367,848 (web page, stale) vs 424,516 (Dec 2025) is a true like-for-like growth of ~15%.

R4-03-regulatory-business-gaps.md - 9.1 Registered drone operators in the EU/EASA states — a real figure at last
Caveats to state on the site: (1) an "operator" registration is per person/organisation, not per aircraft, and covers the Open and Specific categories; (2) Germany's 825k looks anomalously high relative to population-comparable France/Italy and may reflect a different counting basis (individual vs. commercial registers) — flag it; (3) the number is registrations held, not active flyers, and EU registrations renew, so lapse is not visible; (4) Liechtenstein shows 0 because it is administered with Switzerland. [UNRESOLVED] The number could not be read directly off an EASA page — the IAM Hub dashboard is JavaScript-rendered and EASA's HTML pages carry no headline figure.

Editorial line for the site: "As of September 2026, U-space exists in EU law but barely in EU airspace. One designated area (San Salvo, Italy, from late 2024) and one certified service provider (ANRA, May 2025) are the only concrete milestones we can date. A recreational flyer in the EU will not encounter a U-space airspace today." — and flag it as a live tracker item, because this is exactly the kind of claim competitors state vaguely.

Revenue per click ranking is unchanged and now firmer: course affiliates (Pilot Institute 20% of $249 ≈ $50/sale) ≫ FPV retailers (RaceDayQuads 8%, iFlight up to 5%, GetFPV/RadioMaster ~3%) ≫ Amazon (4% of a $759 Mini ≈ $30/sale, but 24 h cookie) ≫ camera superstores (B&H ~3.5%, Adorama 2%).
R4-03-regulatory-business-gaps.md - 10.3 Strategic reading
Cookie length is the real differentiator for expensive, considered purchases. Adorama's 30 days and iFlight's 30 days beat Amazon's 24 hours and B&H's 60 hours by a wide margin for a $1,500 drone that a reader researches for a fortnight.
R4-03-regulatory-business-gaps.md - 10.3 Strategic reading
iFlight's ban on search-engine marketing and brand-keyword bidding, and DJI's identical restriction, mean a paid-search strategy has to route through Amazon or the course affiliates.
R4-03-regulatory-business-gaps.md - 10.3 Strategic reading
Insurance is a dead end for affiliate revenue: SkyWatch pays per lead on undisclosed terms with a $250 payout floor, and Coverdrone cannot pay publishers at all because UK insurance introduction is FCA-regulated. Cover insurance editorially, not commercially.
R4-03-regulatory-business-gaps.md - 10.3 Strategic reading
Two FPV retailers publish nothing (GetFPV, and Pyrodrone has no programme at all). Treat "undisclosed" as a negotiating position: ask for a rate in writing and a 30-day cookie before linking.

R4-03-regulatory-business-gaps.md - Where a hobby-drone newsletter lands
A hobby-drone list is not "Tech News" and not B2B SaaS. It sits between Creator/Lifestyle ($34 median) and Tech News ($58 median), and its realistic advertiser pool (FPV retailers, component brands, training providers, insurers) is small and price-sensitive.
R4-03-regulatory-business-gaps.md - Where a hobby-drone newsletter lands
Plan on $25–$45 CPM for a well-engaged hobby-drone list of 5k–50k subscribers, i.e. $125–$2,250 per send across that range.
R4-03-regulatory-business-gaps.md - Where a hobby-drone newsletter lands
A commercial/Part 107 or enterprise-operator segment of the same list can be sold at $60–$110 CPM (Tech News top decile / B2B-adjacent), because the advertiser is buying buyers of $300 courses, $750 insurance policies and $5k+ airframes. Segmenting the list by recreational vs. Part 107 is the single highest-leverage monetisation decision.
R4-03-regulatory-business-gaps.md - Where a hobby-drone newsletter lands
Below ~5,000 subscribers, sell flat-rate placements, not CPM (consistent with R3-06 §8.2).

R4-03-regulatory-business-gaps.md - Reading of the set
Bardwell's 438K is flat versus R3-06's reading two days earlier and versus the same figure cited through 2026 — the FPV-education audience is mature, not growing. Consistent with the FAA's 1.0% recreational CAGR forecast (§7.3).
R4-03-regulatory-business-gaps.md - Reading of the set
Captain Drone grew ~6% in 16 months — consumer camera-drone content still grows slowly.
R4-03-regulatory-business-gaps.md - Reading of the set
The training brands are deliberately small on YouTube (Pilot Institute 154K / 32M views over 1,170 videos; UAV Coach 91.8K / 8.3M over 513). Their traffic and revenue come from organic search and course sales. YouTube subscriber count is a poor proxy for business size in this niche — the most important correction to make when the site writes about competitors.
R4-03-regulatory-business-gaps.md - Reading of the set
Two of the ten "major drone channels" on the brief are not YouTube businesses at all (Jasper Ellens, and Mads Tech on current evidence). Build the competitive set from web traffic and revenue model, not subscriber counts.

No index value below is measured. Every number must be read manually at trends.google.com and screenshotted with a date before publication. What follows is a documented direction hypothesis plus the corroborating hard data found this round.

Term — Expected direction 2023 → Sept 2026 — Corroborating evidence found this session — Confidence
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
"FPV drone" — Structural rise 2022–24, then plateau or mild decline through 2025–26. The 2022–24 rise is substantially war news, not hobby intent — Ukraine/Russia FPV coverage. Expect a flat hobby baseline under a decaying news spike — Bardwell's 438K subscribers flat (§12); FAA recreational registrations down 18% (5,810→4,782/month, 2024→2025) [VERIFIED §7.3]; FAA forecasts recreational fleet CAGR of only 1.0% to 2030 [VERIFIED] — Medium
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
"DJI Mini" — Sharp Q4 holiday seasonality plus launch-day spikes, with a structural break downward in the US from Dec 2025 as the FCC Covered List stopped new DJI authorizations and stock thinned. Expect US and worldwide to diverge for the first time — the most interesting chart on the list — FCC adds all foreign-produced UAS to the Covered List 2025-12-22; DJI SDR Transmission 2 launched 2026-09-01 not available in the US; 25 blocked 2026 US launches claimed by DJI [R3-01] — Medium-high
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
"drone ban" — Event-spike only, near-zero baseline. Expect named spikes: NDAA FY25 (Dec 2024), FCC Covered List (Dec 2025), DJI v. FCC filing (Feb 2026), FCC "military-grade" PN (Jul–Sep 2026), Section 232 tariffs (Sep 3, 2026). Great for news-jacking, useless as evergreen SEO — Dated event list in R3-01 §10; 3,824 public comments filed in PS Docket 26-189 by Sept 2026 — High
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
"Part 107" — Flat to gently rising, strongly counter-seasonal to consumer terms (weekday/Q1 professional intent). The commercial side is the growing side — FAA: commercial fleet +5.0% CAGR to 2030 vs recreational +1.0%; remote pilot certificates 493,396 at Dec 2025 → 628,600 by 2030 [VERIFIED §7] — Medium-high
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Manual measurement protocol for whoever checks this (worth documenting on the site as method):
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Compare in one query, 5-year window, Worldwide and then United States separately — the US/worldwide divergence for "DJI Mini" is the story.
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Separate hobby intent from war news by adding "FPV goggles" and "tiny whoop" as controls. If "FPV drone" rises while both controls stay flat, the rise is news, not hobby.
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Annotate the four regulatory dates above on each chart.
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Export CSV, store it with the retrieval date, and re-run quarterly — a dated, annotated trends chart is itself one of the content gaps identified in R3-06 §3.3 (data journalism).
R4-03-regulatory-business-gaps.md - 13. Google Trends 2023–2026: "FPV drone", "DJI Mini", "drone ban", "Part 107"
Cross-check absolute volume with a keyword tool (Ahrefs/Semrush), because Trends gives relative index only and a rising index on a collapsing base is a trap.

Lithium batteries — ICAO power-bank rules effective Mar 27, 2026: 2 per passenger, 100 Wh, carry-on only, no charging or use in flight. Drone packs are spare batteries, not power banks — this is a reading of the rule, not a published ruling. The FAA's drone-specific PackSafe page is stale to 2024.

DJI O4 codec and bitrates: H.265 on both air units. The 100/130 Mbps figures are recording bitrates (O4 100, O4 Pro 130, O3 was 150); the live feed is capped near 60 Mbps with Goggles 3/N3 and 50 Mbps with Goggles 2/Integra. DJI states Gyroflow compatibility. O4 Wide: 159° FOV, 1/2" sensor, 4K60, H.265, 13.3 g, 20 ms, 10 km FCC, 60 MHz bandwidth, $159.99 — absent from DJI's spec page, and a "60 Mbps" claim circulating for it is a mis-transcription of 60 MHz. Avata 360 (O4+): 60 Mbps live, ~130 ms latency on the controller screen (not comparable to goggle figures), 20 km FCC, 180 Mbps H.265 recording.

Motor thrust: four full 100%-throttle tables were transcribed from Mini Quad Test Bench raw endpoints (SunnySky E-R2207 1800KV, QSL Cinematic 2207 1750KV, T-Motor F60 Pro II 2207, Xilo 2207 2550KV) with thrust, current, voltage, power, g/W and RPM per prop. Correction: the SunnySky peak row is 2,053 g at 46.4 A and 1,069 W → 1.92 g/W; "2,098 g" was a headline figure. Velox V2207 V3, EMAX ECO II, 1404 and 2806.5 tables remain image-only or paywalled.

Batteries: no semi-solid or silicon-anode hobby/FPV pack exists. Grepow/Tattu semi-solid (280–500 Wh/kg, 16–99 Ah, no published C-rate) is commercial-UAV only, and their FPV line is all LiPo. On internal resistance, AC 1 kHz charger readings always come out lower than DC-pulse measurements; the report tabulates mΩ bands by pack type.

Remote ID enforcement: enforceable since Mar 16, 2024. FAA Bulletin 2026-1 (Feb 2026) makes legal action the default and explicitly names 14 CFR §89.105; 18 penalties from $1,771 to $36,770 and 8 certificate actions are recorded, with a $75k maximum — but no published penalty actually cites Part 89.

Control-link latency: Tracer 3 ms at 250 Hz (vendor), Crossfire 13.9 ms measured at 50–150 Hz dynamic, ELRS's "5 ms" claim. The report derives a source-verified latency floor (½ packet interval + time-on-air) for all 13 ELRS modes, showing Crossfire's 13.9 ms is 900 MHz LoRa physics rather than firmware.
