The Witch 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 248 lb (112 kg). It features a strut-braced high-wing, T-tail, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1][2]
The aircraft is of mixed construction, including bolted-together aluminum tubing, 4130 steel tubing, wood and dope and aircraft fabric. Its 30 ft (9.1 m) span wing is supported by a single lift strut per side, with jury struts, and incorporates a unique folding mechanism. The wing folds by first hinging the outer panels onto the inner panels and then the whole wing pivots on a central steel post to allow positioning fore-and-aft for towing on its landing gear or for storage.[1]
The Witch accommodates its pilot on an open seat, with a small cockpit fairing with a windshield. The controls are conventional three-axis, with half-span ailerons and an all-flying stabilator. The tricycle landing gear features nose wheel steering and includes a small tail caster. The standard engine supplied was the Zenoah G-25 single cylinder, two-stroke aircraft engine of 22 hp (16 kW). The engine is mounted underneath the center of the wing and drives the pusher propeller though a short extension shaft.[1]
