Design and development
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing a two-seats-in-side-by-side configuration open cockpit, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft fuselage is made from welded steel tubing, with the wing built from aluminium tubing with wooden ribs. The airframe is covered in doped aircraft fabric. Its 11.34 m (37.2 ft) span wing has an area of 15 m2 (160 sq ft) and is supported by cabane struts, V-struts and jury struts. The wings are quickly detachable for storage. Standard engines available are the 70 hp (52 kW) Sauer 2.1 four-stroke Volkswagen air-cooled engine and the 64 hp (48 kW) Rotax 582 two-stroke powerplant.
While still in production in 2015, the aircraft was only built on request.
