Seeing the need for training aircraft, Micro-Aviation decided at the end of 1981 to launch some two-seater microlights. To this end, the firm asked Don Mitchell to give it the benefit of his experience in this matter and a prototype called the Two-Seat Trainer was duly shown at Oshkosh in August 1982.
By 1983 it has not gone into serious production. The aircraft shown was a direct development of the B10 Mitchell Wing, enlarged and strengthened. It was intended that the two-seater should use a Konig SD570 four -cylinder two-stroke engine.
