The FC100 Hydrogen-Electric UAV is a heavy-lift cargo drone featuring large payload capacity and ultra-long endurance. Supporting two power supply modes, it redefines professional aerial transportation and breaks the boundaries of more application scenarios. In lithium battery mode, it delivers a maximum payload of 80 kg with a flight endurance of 7 minutes. In hydrogen-electric mode, it achieves 40 minutes of endurance under full load and 50 minutes with no load. The two power modes can be switched freely to handle transportation tasks in various complex scenarios. Capable of cross-mountain and cross-water operations with extended flight time, it builds a new-generation aerial cargo corridor for mountain hoisting, power material delivery, emergency fire rescue and waterborne transportation.
