DLE128HD Hybrid UAV Engine – 128cc Water-Cooled Twin-Cylinder Power System

The DLE128HD is a high-performance hybrid UAV engine launched in March 2020, designed specifically for industrial-grade drones requiring long-endurance and stable power output. It features a horizontal-opposed twin-cylinder two-stroke water-cooled piston engine that delivers up to 12 horsepower at 8300 RPM. Its advanced water cooling system ensures efficient heat dissipation and consistent operation even in challenging environments.

This engine integrates a three-phase permanent magnet generator and operates as an independent closed-loop hybrid power system. It requires no configuration with flight controllers or RC systems, making it a reliable solution for hybrid VTOLs and large fixed-wing UAVs. With a robust design, reliable output, and ease of installation, the DLE128HD stands out as a complete propulsion solution for high-demand aerial missions.
