The Dragon Fish series of UAVs adopt a unique tilt-wingtip design, which effectively integrates the dual advantages of multi-rotor vertical take-off and landing and fixed-wing long-term endurance. It is maneuverable and flexible and can adapt to various complex take-off and landing conditions. The whole machine adopts quick-disassembly and efficient aerodynamic design, which makes the flight performance reach the industry-leading level while being portable and easy to use. The 30km dual-frequency high-definition image transmission realizes ultra-long-distance stable and worry-free operation. The industrial-grade flight control and navigation system ensures that the UAV can fly autonomously throughout the whole process, and it is equipped with different mounts such as dual-light cameras and tri-light cameras to meet the operation needs of different scenarios.
