The new SINUS ultralight motorglider is a strutsless 15 m (49 ft) wing span motorglider with positive and negative flapperons, with airbrakes and tail wheel. All models are made in hi tech composite (epoxy resin, glass, carbon, kevlar). The airfoil used on wings is IMD 029-b, (Orlando, Venuti). The cabin is properly insulated from noise…
The Dart was originally designed to Standard Class rules and first flew in 1964, winning th 1965 OSTIV prize at the World Championships at South Cerney, England. This notwithstanding, a disappointing competitive performance led to the development of the 17 m. Open Class Dart 17, which had a wood and metal bonded spar in place…
The Standard Class Discus A first flew in 1984 using the fuselage and tail unit of the original Ventus with a new unflapped wing. The wing planform is noteworthy as being the first production sailplane to have the now common distictive shape where the leading edge sweepback increases towards the tip, establishing a worldwide trend…

The development of this early all-fiberglass sailplane began at the Swiss Federal Institute of Technology in Zurich under the direction of Prof. Rauscher, first flying with a new fuselage and tailplane married to wings from a schleicher Ka-6 (the Ka Bi-Vo). Further development was taken over by Flug un Fahrzeugwerke (FFA) which used flapped 15…
Three models of the DG-800, which first flew in 1991, have been developed, the unpowered DG-800S, the Rotax powered DG-800A and the liquid cooled buried engine configuration of the 800B substantially reduces noise emissions. Each model comes either with a one piece 18 m. wing or a 15 m wing with tip extensions increasing the…
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 DG-500 comes in a number of sizes which all share the same basic fuselage. The 500T Elan Trainer, which first flew in 1989 has an unflapped 18 m. wing without provision for water ballast; retractable gear is an option. The front cockpit design has been purposely made similar to that of the DG-300 Club.…
The Standard Class successor to the DG-101 featues an HQ airfoil with blow-holes to inject high-energy air into the boundary layer to delay laminar separation. It has fin ballast for center of gravity control. Approach control is by top surface Schemmpp-Hirth type airbrakes. Like other DG ships, the –300 features a parallelogram stick to avoid…
