The Raisner Graffiti is an American ultralight trike that was designed by Bill Raisner and produced by Raisner Aircraft Depot, a division of Leading Edge Air Foils of Peyton, Colorado and introduced about 1997. When it was available the aircraft was supplied as a kit for amateur construction.[1]
By 2014 the aircraft was no longer offered for sale by Leading Edge Air Foils.[2]
Design and development
[edit]The Graffiti was designed with the goals of maximizing safety, performance and simplicity of construction. It was intended to comply with the US FAR 103 Ultralight Vehicles rules, as a two-seat trainer. 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.[1][3]
The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 33.80 ft (10.3 m) span wing is supported by a single tube-type kingpost, uses an "A" frame weight-shift control bar and has a wing area of 160.0 sq ft (14.86 m2). The acceptable power range is 41 to 64 hp (31 to 48 kW) and the standard powerplant used is a de-rated twin cylinder, air-cooled, two-stroke, dual-ignition 53 hp (40 kW) Rotax 582 engine, optimized for quiet operation.[1]
The aircraft has an empty weight of 341 lb (155 kg) and a gross weight of 872 lb (396 kg), giving a useful load of 531 lb (241 kg).[1]
The standard day, sea level, no wind, take off with a 53 hp (40 kW) engine is 100 ft (30 m) and the landing roll is 150 ft (46 m).[1]
