Design and development

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 251 lb (114 kg). It features a strut-braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in tractor configuration.[1][2]

The aircraft fuselage is made from aluminum tubing. Its 35 ft (10.7 m) span wing is constructed in a similar manner to the Ultraflight Lazair's wing. It is built from D-cell spar and leading edge, with foam ribs bonded to the spar. The wing is then covered with transparent Mylar film for covering. The wing incorporates a quick-folding mechanism that allows it to be folded back along the fuselage for ground transport or for storage. The pilot is accommodated on an open seat without a windshield. The landing gear features suspension on all wheels and a steerable nosewheel. The Cuyuna 430R engine of 30 hp (22 kW) is mounted in front of the wing, above the pilot.[1][2]

Due to its introduction just before the collapse of the US ultralight industry in 1984, the design was not a commercial success and only a small number were completed and sold.[1]
