Design and development
The Twister is a development of the Pipistrel Spider. It incorporates a bent main pylon, which allows more seating room for the rear seat occupant, more streamlined main landing gear legs and a Rotax 912 engine. The Twister was designed for competition use, but has been successful in the recreational market as well.[1]
The Twister was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's 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 wheel pants and a single engine in pusher configuration.[1]
The aircraft is made from welded steel tubing, with its double surface wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912UL 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 42 litres (9.2 imp gal; 11 US gal) the payload is 222 kg (489 lb).[1]
