Design and development

The Micropfeil was designed to comply with the Fédération Aéronautique Internationale microlight category and the US FAR 103 Ultralight Vehicles rules. It features a cable-braced hang glider-style high wing, weight-shift controls, a single-seat 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 Schönleber Speed 14 m2 (150 sq ft) wing covered in Dacron sailcloth. The 10.8 m (35.4 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 two-tube structure. The powerplant is a twin-cylinder, air-cooled, two-stroke, single-ignition 40 hp (30 kW) Rotax 447 engine.[1]

The aircraft has an empty weight of 80 kg (176 lb) and a gross weight of 300 kg (661 lb), giving a useful load of 220 kg (485 lb). With full fuel of 25 litres (5.5 imp gal; 6.6 US gal) the payload is 206 kg (454 lb).[1]
