The successor to the DG-202/DG-400, the unpowered 15 m. racing class DG-600 first flew in 1987, followed by the mast mounted self- launching DG-600M in 1989. The fuselage is based on that of the DG-400, but with a more slender tailboom. The wing has a thin section with fully span flaperons. Approach control is by the top surface double panel Schemmpp-Hirth type airbrakes. There is also a fin ballast tank which carries 7 kg / 15.4 lb of water.
The 600 came with four different wingtip configurations- conventional 15 m, 15 m with winglets, conventional 17 m. and swept back 18 m.
The DG-600/18 and DG-600/18M named Evolution have gross weight of 480 kg/ 1,058 lb and 440 kg/ 970 lb respectively. In the 600M, main ballast is reduced to 120 kg/ 265 lb.
