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.
The Twister was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 4500NaN0. 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.
The aircraft is made from welded steel tubing, with its double surface wing covered in Dacron sailcloth. Its 101NaN1 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 800NaN0 Rotax 912UL engine.
The aircraft has an empty weight of 1980NaN0 and a gross weight of 4500NaN0, giving a useful load of 2520NaN0. With full fuel of the payload is 2220NaN0.
