The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 5.5 m (18.0 ft) span wing has a combined area of 9 m2 (97 sq ft) and ailerons on the bottom wing only. The aircraft was designed for the 65 hp (48 kW) Volkswagen air-cooled engine, but other variants have been developed that use a variety of engines, including the 110 hp (82 kW) Rotec R2800 radial engine.
