Design and development

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]

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]

gollark: So you should probably do something else.
gollark: PotatOS won't boot off a startup disk.
gollark: Just get another computer, `set shell.enable_disk_startup false` (or something like that), plug in a disk drive, make a simple program to automatically delete `startup` on any disk you put in.
gollark: Very easily?
gollark: ... you know you *can* wipe them?
