Design and development

The Clipper was designed as a trainer for school use and complies with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 350 kg (772 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit without a cockpit fairing, tricycle landing gear and a single engine in pusher configuration.[1]

The Clipper was developed into the longer range Raj Hamsa Voyager.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface Raj Hamsa-made wing covered in Dacron sailcloth. Its 10.1 m (33.1 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503 engine or the twin cylinder, air-cooled, two-stroke, dual-ignition 65 hp (48 kW) Hirth 2706 engine.[1][2]

The aircraft has an empty weight of 160 kg (353 lb) and a gross weight of 350 kg (772 lb), giving a useful load of 190 kg (419 lb). With full fuel of 25 litres (5.5 imp gal; 6.6 US gal) the payload is 172 kg (379 lb).[1]
