With 18 m (59 ft) span wings it is fully certified for aerobatics (+7 -5 g); with a 20 m (66 ft) span wings it is certified for limited aerobatics (+5 -2.65 g).
The engine (DG1000T) is mounted on a pylon aft of the double cockpit. There is a reduction gear (2.3:1.0) between the engine and the two-blade carbon-fibre composite propeller. The propeller was designed by and made in the DG factory.
