UUUFLY
1 / 5
Engineered to transport payloads up to 70kg, this drone delivers a remarkable 25-minute flight time at full capacity. Its innovative coaxial eight-propeller design and a max takeoff weight of 140kg ensure powerful, stable, and safe flight even in challenging conditions (18m/s wind resistance), redefining reliability for critical missions.
Strategic partnerships with leading propulsion manufacturers provide exclusive, calibrated power system adaptations (A12XL, H11M, X11 Max) for tailored performance. After thousands of flight verifications and professional data adjustments, it can still fly safely and stably under extremely heavy loads.
It supports various transportation methods such as hoisting, storage, and throwing, and has a highly modular design. Task scalability enables the provision of customized adaptation services based on user needs. Strategic partnerships with leading propulsion system manufacturers like Hobbywing and T-motor possess an exclusively calibrated PiD library, and with extensive experience in holistic drone integration solutions, deliver richer and more refined customized services for your flight experience.
