Krasniye Kryl'ya Deltacraft MD 50C

Design and development

The Deltacraft MD-50C 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 380 kg (838 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.

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. The wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503 engine or liquid-cooled 64 hp (48 kW) Rotax 582. With the 582 engine the aircraft has an empty weight of 178 kg (392 lb) and a gross weight of 380 kg (838 lb), giving a useful load of 202 kg (445 lb). With full fuel of 80 litres (18 imp gal; 21 US gal) the payload is 144 kg (317 lb).

A number of different wings can be fitted to the basic carriage, including a 14 m² (150 sq ft) wing produced by the company.
