Design and development

[edit]

The aircraft 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 253 lb (115 kg). It features a cable-braced high-wing, a wide single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from aluminum tubing, with the wings and tail surfaces covered in Dacron sailcloth. Its 32 ft (9.8 m) span wing is cable braced from a single kingpost. The pilot is accommodated on a double-width seat designed for wide and heavy pilots or for two smaller people, to a maximum occupant weight of 400 lb (181 kg). The standard Kawasaki 440 40 hp (30 kW) engine is mounted at the trailing edge of the wing, with the rearwards-facing propeller in between the tail boom tubing.[1][2]
