Design and development

The Airpfeil was designed to comply 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 400 kg (882 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 aircraft is made from bolted-together aluminum tubing, with its double surface Vento 13 m2 (140 sq ft) wing covered in Dacron sailcloth. The 9.5 m (31.2 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The wing is supported by a three-tube tetrahedral structure, which is no longer common on modern trikes, but provides good strength at light weight. The powerplant is a twin-cylinder, liquid-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 582 engine.[1]

The aircraft has an empty weight of 130 kg (287 lb) and a gross weight of 400 kg (882 lb), giving a useful load of 270 kg (595 lb). With full fuel of 62 litres (14 imp gal; 16 US gal) the payload is 225 kg (496 lb).[1]
