Design and development

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]
