Design and development

The Royal 912 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, tricycle landing gear with wheel pants and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its single surface wing covered in Dacron sailcloth. Its 10.48 m (34.4 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 912 or 100 hp (75 kW) Rotax 912S engine. The aircraft has an empty weight of 230 kg (507 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 220 kg (485 lb). With full fuel of 55 litres (12 imp gal; 15 US gal) the payload is 180 kg (397 lb).[1]

The aircraft carriage is manufactured under sub-contract in Slovenia. A number of different wings can be fitted to the basic carriage, but the standard wing is the Drachen Studio Kecur EOS 15 with a wing area of 15 m2 (160 sq ft) and which is equipped with spoilers.[1]
