The Glaser-Dirks DG-600 is a
Design and development
The DG-600 fuselage is based on the fuselage of the DG-400 but with a more slender tailboom which also incorporates a tailfin ballast tank with a capacity of 7 liters. The design of the canopy and the instrument panel is practically the same as on other DG gliders.
The control surfaces incorporate
The negative effects (i.e. a stall without much warning) of this design are most pronounced on 15-meter wingspan without winglets. These characteristics caused the relative unpopularity of this glider and only 114 aircraft were produced (partially because the moulds were later destroyed in a factory fire). Later versions with 17 and 18 m wingspan offer much better low-speed handling.
