Design and development

The P-Craft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 165 lb (75 kg). It features a strut-braced high-wing, a single-seat, open cockpit, conventional landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from aluminum tubing, with the aft fuselage welded steel tubing. Its tapered 32.5 ft (9.9 m) span wing has no wing-mounted control surfaces. The wing is covered in doped aircraft fabric. Pitch is controlled conventionally, while yaw is controlled by the rudder, actuated by sideways movement of the control stick. The high degree of wing dihedral produces rolling motion from yaw coupling. The landing gear is bungee-suspended and the tailwheel is steerable. The single cylinder, two-stroke Cuyuna 215 20 hp (15 kW) engine is mounted behind the open pilot's seat, with the propeller rotating in between the top and bottom tail structural members.[1]

gollark: I doubt they're vulnerable to obvious XSS ættacks.
gollark: And yet people apparently enjoy that sort of thing for unfathomable reasons, so you're wrong.
