Design and development

The Raptor was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). It also carries South African government certification. 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, tricycle landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from steel tubing, with its double-surface Raptor 17 XP wing covered in Dacron sailcloth. Its 10.5 m (34.4 ft) span wing incorporates 34 stiffening battens, is supported by a single tube-type kingpost and uses an "A" frame control bar. The basic aircraft offered a standard 30 kW (40 hp) Rotax 447 twin cylinder, two stroke, air-cooled, single ignition engine, while the Raptor 912 model came equipped with the 60 kW (80 hp) Rotax 912UL four cylinder, four-stroke air- and liquid-cooled, dual ignition engine. The 48 kW (64 hp) Rotax 582 was also a factory option. The aircraft was supplied as a kit that requires 20 to 30 hours to assemble.[1][2]

Factory standard equipment included two bucket seats, side skirts with integral saddle bags and a nose wheel fender. In 2000 the carriage cost US$3500 and the Raptor 17 XP wing cost $4500. The aircraft's carriage was designed so that it would also accept French Cosmos ULM wings. Fifty examples had been delivered by 2000.[1]
