The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 4500NaN0. It features a "topless" strut-braced hang glider-style high-wing, weight shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 31.51NaN1 span wing is supported by streamlined struts, in place of the more commonly used cables and kingpost. The Apache is controlled with a conventional weight shift "A" frame control bar. Standard features include a fiberglass cockpit fairing, wheel pants, nosewheel brakes and stowage bags. Dual control steering and throttle are optional for flight training use. The supplied engines include the Rotax 503 twin-cylinder, two-stroke, air-cooled powerplant of 500NaN0 and the Rotax 582 twin-cylinder, two-stroke, liquid-cooled powerplant of 640NaN0.
The strut-braced wing provides a number of advantages over the traditional cable braced wing, including reduced overall height for hangaring, reduced drag and improved appearance.
