Product overview

The Autel Robotics Dragonfish-25 is a powered tilt-rotor flight platform for public safety, energy inspection and emergency management. It combines multirotor vertical takeoff and landing with fixed-wing flight. Its narrow fuselage, partially embedded motors and automatic propeller locking in fixed-wing mode address aerodynamic drag, while a high-strength composite body and quick-release construction support field deployment. Assembly takes within 10 minutes, followed by a 10-second system self-check after power-on. Flight functions include waypoint missions, intelligent tracking, target recognition and takeoff and landing on moving platforms.

Payload integration uses an E-type quick-release gimbal interface accepting T5, T5L and L20T gimbals. Aircraft weight is 29 kg including intelligent batteries and propellers but excluding the gimbal, with a 10 kg maximum payload and 39.0 kg maximum takeoff weight. The T5 gimbal configuration includes a 128GB microSD card. Aircraft dimensions reach 3025.7 × 4566 × 823.6 mm with propellers installed. The platform provides built-in ADS-B reception, multiple GNSS constellations and RTK positioning, with accuracy varying by flight mode and positioning status.

Maximum range is 250 km with L20T or 220 km with T5/T5L. Corresponding maximum loaded flight times are 240 and 210 minutes under nearly windless conditions at 18 m/s cruising airspeed, as reference test results. Wind resistance is 10 m/s in rotor mode and 15 m/s in fixed-wing mode. Aircraft operation spans −20°C to +50°C, and IP45 protection may fail following prolonged aging and wear. FCC signal-distance figures require the aircraft, tracking antenna and ground station together, without interference or obstructions; frequency access also carries regional and indoor-use restrictions.
