Design and development[]

The Silent Racer 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 with a windshield, retractable tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from composites, with its double surface wing covered in Dacron sailcloth. A variety of wings can be used from 10 to 12 m (32.8 to 39.4 ft) in span and 10 to 15 m2 (110 to 160 sq ft) in area, all supported by a single tube-type kingpost and employing an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 53 hp (40 kW) Hirth 2704 engine or 65 hp (48 kW) Hirth 2706. The aircraft has an empty weight of 200 kg (441 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 250 kg (551 lb). With full fuel of 57 litres (13 imp gal; 15 US gal) the payload is 209 kg (461 lb).[1]
