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 243 lb (110 kg). It features a strut-braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from bolted-together aluminum tubing, with the wings and tail surfaces covered in Dacron sailcloth. Its tapered planform, single-surface, 30.5 ft (9.3 m) span wing is supported by both lift struts and jury struts. The wing features 3/4 span ailerons. The pilot is accommodated in an open seat without a windshield. The tail surfaces are mounted on tubes that travel beside and below the pusher engine and propeller. The tricycle landing gear features main gear suspension.[1][2]

The Mark IV appeared just before the collapse of the US ultralight market in 1984 and so few were produced or sold.[1]
