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.
The tail surfaces are mounted on tubes that travel beside and below the pusher engine and propeller.
[1][2] The Mark IV appeared just before the collapse of the US ultralight market in 1984 and so few were produced or sold.
