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 flaperons which serve as both flaps and ailerons. The wing has a newly designed thinner airfoil and higher aspect ratio than previous types of DG gliders. This gives a higher performance but at a cost of worse slow-speed characteristics, making it less suitable for gliding competitions with frequent gaggles in thermals. The same problem is also noticeable on LS-7 and ASW-24 gliders, where improved performance was to be achieved with thinner airfoils.
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.

Die Glaser-Dirks DG-600 ist ein einsitziges Hochleistungs-Segelflugzeug mit Wölbklappen von DG Flugzeugbau. Das Flugzeug aus kohlenstofffaserverstärktem Kunststoff (CfK) kann als Nachfolger von DG-200 und DG-400 betrachtet werden und wurde von Beginn an mit 15 und 17 Metern Spannweite angeboten. Ab 1989 wurde die Modellpalette um eine eigenstartfähigen Variante, DG-600M, erweitert. Ab 1991 wurden auch Varianten mit 18 Metern Spannweite durch größere Ansteckflügel (DG-600/18, DG-600/18M) und Winglets angeboten.- [en] Glaser-Dirks DG-600
