Design and developmentEdit

Design of the A-20 began in 1990, with the first prototype making its maiden flight on 5 August 1991, with the first production aircraft flying on 15 August 1993.[3] The A-20 is constructed with a fiberglass forward fuselage and cockpit with aluminium wings and tail surfaces covered in doped aircraft fabric. The wing is fitted with half-span ailerons and flaps. The flaps are quite effective and lower the landing speed to 30 mph (48 km/h). Flaperons are available on some models. The conventional landing gear has steel sprung main gear legs.[1][2]

The A-20 was originally designed for the 50 hp (37 kW) Rotax 503 two-stroke aircraft engine. The low drag airframe produces acceptable performance on this low power output. Optional engines include the 64 hp (48 kW) Rotax 582 and 100 hp (75 kW) Rotax 912ULS[1][4]

Operational historyEdit

An A-20 won the European Microlight Championship in 2002.[2]
