DE500 500cc Twin-Cylinder Air-Cooled Engine for Large Industrial UAVs

Description 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.   Core Advantages Twin-cylinder / two-stroke air-cooled architecture for maximum power density. High-torque powertrain: 44.88 hp enabling serious lifting capability. 220 kg MTOW support for professional heavy-duty UAV missions. Solid-state magneto ignition for stable, maintenance-free operation. High-strength alloy steel crankshaft ensures long service durability. Optional 350W / 500W / 1000W generator for avionics and payload power supply. Flexible installation for push or pull propulsion configurations.
