The Twin was designed as a trainer for the Air Creation Fun Racer. It complies 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 385 kg (849 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit without a cockpit fairing, tricycle landing gear with wheel pants and a single engine in pusher configuration.^[1]

The aircraft is made from bolted-together aluminium tubing, with its Air Creation Fun 450 single surface wing covered in Trilam Dacron sailcloth, with a Mylar leading edge. The 10.06 m (33.0 ft) span wing is supported by a single tube-type kingpost, uses an "A" frame weight-shift control bar and has a wing area of 17.4 m² (187 sq ft). The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503 engine. The aircraft has an empty weight of 129 kg (284 lb) and a gross weight of 385 kg (849 lb), giving a useful load of 256 kg (564 lb). With full fuel of 39 litres (8.6 imp gal; 10 US gal) the payload is 229 kg (505 lb).^[1]
