Design and development
The aircraft was designed to comply with US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). It features a biplane wing configuration, a single-seat, open cockpit and a single engine.
The aircraft is made from aluminum tubing, riveted together using gussets. Its top wing features full-span ailerons. The wings and tail are covered with aircraft fabric that is glued into place, heat shrunk and then finished with latex house paint, with two coats of paint on bottom surfaces and three on top to provide extra UV protection. The conventional landing gear includes a steerable tailwheel.
