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.[1]

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.[1]

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).[1]
