PowerTrike II

Design and development

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). The aircraft has a 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 with a cockpit fairing, tricycle landing gear with optional wheel pants and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 10.5 m (34.4 ft) span Bautek Pico L wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The wing is mounted to a bi-pole type pylon, plus a front strut, which provides additional rigidity and strength. The powerplant is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine or a four stroke95 hp (71 kW) BWM 1150 motorcycle engine.

The aircraft has an empty weight of 198 kg (437 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 252 kg (556 lb). With full fuel of 54 litres (12 imp gal; 14 US gal) the payload is 213 kg (470 lb).
