‑Max flight altitude: 7000 m ‑Max control range: 20 km ‑Max speed: 150 km/h ‑Empty‑flight endurance: 45 min ‑Standard payload: 2 kg ‑Max payload: 3.5 kg ‑Payload flight time: 10‑15 min

Review note: Built on high‑strength carbon‑fiber frame. ELRS 915MHz for long‑distance control, 5.8G video transmission. 7‑inch heavy‑duty platform with 45‑min empty‑flight time and up to 3.5 kg payload.

Key Strengths In Real Test

1. Robust carbon‑fiber airframe

High‑strength carbon‑fiber construction, compact 276 mm footprint. Better anti‑deformation performance than plastic frames for high‑speed flight and minor impacts.

2. 20 km long‑range ELRS 915 MHz link

ELRS 915 MHz receiver delivers better anti‑interference than standard 2.4G radio. Up to 20 km control radius in open‑sky conditions for long‑distance field missions.

3. 7000 m high‑altitude capability

Supports flight altitude up to 7000 meters, maintains power output in high‑altitude mountainous terrain for plateau operations.

4. 150 km/h high‑speed cruise

Top speed 150 km/h, fast response to reach target points for emergency reconnaissance.

5. 45‑minute empty‑flight endurance

45‑min flight time without payload, competitive among 7‑inch FPV platforms, supporting long‑range patrol and reconnaissance.

6. Powerful payload for cargo delivery

Standard payload 2 kg, peak payload 3.5 kg. Supports cargo dropping or special‑mission payload installation.

Note: Flight time drops sharply once payload is attached.

7. 165° enhanced night‑vision wide‑angle camera

Ultra‑wide 165° field‑of‑view with night‑vision enhancement. Usable at dusk and low‑light conditions for day‑and‑night surveillance.

Tested Drawbacks & Limitations

❶ Severe endurance drop under payload

45‑min empty‑flight time drops to only 10‑15 min with payload. Max 3.5 kg payload is for short‑time delivery only, not for long‑duration loaded cruise.

❷ 20 km & 7000 m are open‑field theoretical values

Range and altitude ratings are achieved under unobstructed open‑sky conditions. Performance degrades in urban canyons, dense woods or heavy EMI environment. Do not push to absolute limits.

❸ No built‑in obstacle‑avoidance

This is a pure manual FPV platform without obstacle‑sensing sensors. Fully pilot‑driven. High crash risk for inexperienced users.

❹ 5.8G VTX vulnerable to signal interference

5.8 GHz video link may suffer from static or dropout in heavy‑RF‑noise urban areas. High‑gain antennas are recommended for long‑range missions.

❺ High‑skill threshold, not for beginners

It is a professional FPV aircraft requiring tuning and FPV flying skills. New pilots face high crash risk.

Suitable & Unsuitable Use‑cases

✅ Ideal scenarios

1. Long‑range wilderness reconnaissance & patrol
2. Emergency cargo delivery with 2‑3.5 kg payload
3. High‑altitude mountain / plateau missions
4. Custom special‑payload integration
5. Professional FPV long‑range flight practice

❌ Not recommended for

1. Absolute beginners without FPV experience
2. Missions requiring long‑time flight under heavy payload
3. Dense urban built‑up‑area operations
4. Users seeking obstacle‑avoidance and automatic flight

Important Pre‑flight Tips

1. Pilot must have solid FPV operation & ELRS tuning knowledge.
2. Keep safety margin, do not fly to maximum theoretical range.
3. Heavier payload equals shorter flight distance, plan routes accordingly for delivery tasks.
4. Install high‑gain antennas to improve 5.8G link for long‑range flight.
5. Comply with local UAV regulations, observe airspace restrictions for high‑altitude flight.
6. Prepare spare propellers and frame components for crash damage.

Final Review Verdict

Pros

1. Rugged high‑strength carbon‑fiber 7‑inch airframe
2. ELRS 915 MHz link for up to 20 km control distance
3. 7000 m maximum altitude for plateau & mountain work
4. 150 km/h top speed, 45‑min empty‑flight endurance
5. Max 3.5 kg payload capacity for cargo delivery & custom payloads
6. 165° enhanced night‑vision wide‑angle camera

Cons

1. Very short flight time under payload (10‑15 min)
2. Zero obstacle‑avoidance system, heavy reliance on pilot skill
3. Specs are for open‑sky environment; performance drops in complex terrain
4. 5.8 GHz VTX susceptible to radio interference; antenna upgrade suggested

Best for: Experienced FPV pilots & professional teams for long‑range recon, cargo delivery and high‑altitude special missions. If you are a beginner wanting obstacle‑avoidance and easy‑to‑use inspection functions, refer to G330 inspection drone instead.
