DE Engine • Professional Power System for Heavy-Lift & Long-Endurance Platforms

The DE500 is a high-power 500cc twin-cylinder gasoline engine purpose-built for large industrial UAVs requiring extreme thrust, heavy-lift capability and long-range mission performance. With a maximum output of 44.88 hp (33 kW) and up to 60 kg static thrust at 100 m altitude, the DE500 enables drones to achieve MTOW up to 220 kg, making it an ideal propulsion solution for logistics platforms, border patrol aircraft, disaster-response drones and high-payload VTOL hybrid systems.

Featuring a solid-state magneto ignition, high-strength alloy steel crankshaft, 2500–6000 rpm operational envelope, and optional onboard generator up to 1000 W, the DE500 is engineered for robust reliability and continuous aerial operation in harsh environments. It supports both puller and pusher installations, ensuring broad compatibility with modern heavy UAV airframes.
