==Design and development== The DF02 features a single main rotor, a single-seat enclosed cockpit with an optional bubble canopy, tricycle landing gear and a twin cylinder, liquid-cooled, two-stroke, dual-ignition, fuel-injected {{convert|70|hp|kW|0|abbr=on}} Hirth 3503 engine in pusher configuration.<ref name="WDLA11" />

The aircraft uses a {{convert|7.45|m|ft|1|abbr=on}} diameter, high-inertia Averso Aviation rotor, with a chord of {{convert|21.6|cm|in|1|abbr=on}}. The rotor head was designed by GyroTec and includes a disc-style rotor brake, pre-rotator and integral articulation stops. The DF02 has an empty weight of {{convert|175|kg|lb|0|abbr=on}} and a gross weight of {{convert|300|kg|lb|0|abbr=on}}, giving a useful load of {{convert|125|kg|lb|0|abbr=on}}.<ref name="WDLA11" />

The bubble canopy can be removed for flight in warm weather. In 2009 the canopy size was increased to accommodate taller pilots.<ref name="WDLA11" />
