Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). 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.[1][2][3]

The aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 31.5 ft (9.6 m) 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 50 hp (37 kW) and the Rotax 582 twin-cylinder, two-stroke, liquid-cooled powerplant of 64 hp (48 kW).[1][2][3]

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.[1]

A total of 72 examples had been delivered by February 2005.[2]
