This heavy-lift hydrogen fuel cell drone is designed for demanding industrial-grade operations, featuring exceptional payload capacity, ultra-long endurance, and high-precision positioning. It is built as a reliable aerial platform for long-duration and heavy-duty missions.
Powered by the X9 propulsion system, the drone delivers strong and stable thrust, ensuring reliable flight performance under heavy payload and complex operating conditions. With a 1900mm wheelbase, lightweight airframe of 16 kg, and a maximum takeoff weight of 52 kg (at 70% throttle), it supports a wide range of professional payloads.
The system combines a 48V hydrogen fuel cell (3kW rated power) with dual 6S 5300mAh lithium batteries, enabling cooperative power output for enhanced safety and stability. This hybrid energy solution allows an endurance of up to 2 hours with no payload, significantly outperforming traditional battery-powered drones.
Equipped with GPS + Galileo + BeiDou multi-constellation navigation and centimeter-level RTK positioning, the drone ensures precise flight path control. A 20 km HD video transmission system (clear, interference-free environment) provides real-time long-distance monitoring.
With a maximum level flight speed of 18 m/s, cruise speed of 0–15 m/s, and strong climb capability, this platform is ideal for power line inspection, agricultural operations, security surveillance, and logistics transportation, delivering high efficiency and operational reliability.
X9 Propulsion System
The nine-motor propulsion layout provides strong thrust redundancy and flight stability, maintaining safe operation even under heavy payload and challenging environments.
Hydrogen Fuel Cell System
The 48V hydrogen fuel cell delivers 3kW rated power, offering higher energy density and significantly longer endurance compared to traditional lithium batteries, while producing zero emissions.
Hybrid Battery Support
Dual 6S 5300mAh lithium batteries work alongside the hydrogen fuel cell, ensuring continuous power supply and maintaining flight stability even as hydrogen levels decrease.
Heavy Payload Capability
With a maximum takeoff weight of 52 kg, the drone can carry professional equipment such as high-resolution cameras, multispectral sensors, spraying systems, or cargo pods.
Stable High-Speed Flight
A maximum level flight speed of 18 m/s and controlled cruise speed support efficient mission execution, while a climb rate of up to 5 m/s enables operation in complex terrain.
Ultra-Long Endurance
Up to 2 hours of flight time (no payload) dramatically reduces battery swaps and downtime, improving mission efficiency.
Multi-Constellation Navigation
Integrated GPS, Galileo, and BeiDou systems improve positioning reliability and accuracy in challenging signal environments.
Centimeter-Level RTK Positioning
RTK technology ensures precise flight paths, making the drone suitable for high-accuracy tasks such as power inspection and precision agriculture.
20 km Long-Range Video Link
The HD video transmission system supports real-time monitoring over long distances, enabling operators to adjust missions efficiently from the ground station.
Foldable Design
The drone measures 1500 × 1500 × 650 mm when deployed and folds down to 900 × 800 × 650 mm, significantly reducing transport volume and enabling rapid deployment in various environments.

The onboard AI can identify and track targets accurately, even during high-speed maneuvers. This makes simulated strike and reconnaissance exercises much more effective and realistic.2025-12-30
This drone handles like a dream. The responsiveness and agility are outstanding. Perfect for racing with friends or doing freestyle maneuvers. Battery life could be slightly better, but overall, it’s fantastic2025-12-29
The FPV flight experience is extremely immersive. The low‑latency video feed and responsive controls make high‑speed maneuvers feel natural and precise. Flying through tight environments while maintaining situational awareness closely resembles real operational conditions. This is a valuable tool2025-12-29
The AI target recognition system works reliably in both static and moving target scenarios. It can identify and track targets even when partially obscured or moving through cluttered environments. This significantly reduces pilot workload and improves situational awareness during simulated missions2025-12-29
