Design and development
The A1 is a self-launching glider, with the standard 30 kW (40 hp) Rotax 447 mounted in tractor configuration on a retractable pylon behind the cockpit. When retracted the engine is hidden behind two doors. The German importer of the glider equipped his aircraft with a Hirth engine instead of the Rotax powerplant.
The A1 is of mixed composite construction and is built from a combination of carbon-fiber-reinforced polymer, kevlar and PVC foam. The 15 m (49.2 ft) span wing features winglets and produces a 40:1 glide ratio. The landing gear is a retractable monowheel gear. The price of the A1 in 2003 was €39,900.
