Design and development

The Enduro was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 450 kg (992 lb). It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with an optional cockpit fairing, tricycle landing gear with optional wheel pants and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span Air Creation wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine or a twin cylinder, air-cooled, four-stroke, 100 hp (75 kW) BMW 1100 motorcycle engine.[1]

Operational history

The Enduro XC model was used to set several microlight class world records for speed and altitude.[1]
