The DF70 represents a cutting-edge 4-stroke twin-cylinder engine tailored to meet military standards within the aerospace sector. This versatile engine is compatible with both vertical take-off and landing (VTOL) and fixed-wing unmanned aerial vehicles (UAVs), delivering exceptional fuel efficiency, quiet operation, and reliable starting performance.

Boasting a displacement of 70cc and generating a power output of 4.2kW,the DF70 employs a boxer engine design that minimizes vibrations. It also offers flexibility with rotation options for both pusher and tractor configurations. Notably, the engine includes a “limp home” feature, allowing it to operate on a single cylinder if necessary.
