The Glaser-Dirks DG-400 , a self- launching glider based on the DG-202 , was designed by Wilhelm Dirks and had its maiden flight on May 1, 1981 . It can be flown with a 15 m wingspan or with optional wing tips that increase the wingspan to 17 m. The inner wings of the DG-400 are made of CFRP , the outer wings made of GFRP , the fuselage made of GFRP with CFRP in the area of the engine. The engine , a Rotax 505 with 32 kW, is extended and retracted with an electric spindle motor .
The DG-400 has a so-called parallelogram control for the height control, through which an unintentional operation during flight through gusts is to be excluded. The flaps have automatic connections, the ailerons and airbrakes (Schempp-Hirth flaps) are connected manually via L'Hotellier connections. The elevator is automatically connected during assembly.
290 units of the DG-400 were manufactured by Glaser-Dirks Flugzeugbau, today DG Flugzeugbau , between 1981 and 1990. The good customer response was also based on the DEI engine display and control unit, which enabled even less technically experienced people to control a motorized aircraft in the simplest possible way.
