Design and development

The designer was a former employee of Cosmos ULM before that company went out of business. His new company, Gdecouv'R, started out as a parts manufacturer supplying Cosmos owners, before he developed his own aircraft, based on Cosmos designs.[1]

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). It features a cable-braced hang glider-style high wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its standard equipment 9.87 m (32.4 ft) span La Mouette wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin-cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine. The aircraft has an empty weight of 132 kg (291 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 318 kg (701 lb). With full fuel of 55 litres (12 imp gal; 15 US gal) the payload is 278 kg (613 lb).[1]

A number of different wings can be fitted to the basic carriage, including those produced by La Mouette.[1]
