It established several records, including the world altitude record of 6,687 m (21,939 ft) in 1938 in a thunderstorm. Richard du Pont and Chet Decker flew Minimoas to win the US Championships in 1937 and 1938.
It was made out of wood and fabric with cantilevered 'gull' wings. A B-version in 1938 had thinner wings with a modified section and the gull's kink in a different place. The undercarriage was non-retractable. It was the first glider built to carry water-ballast in a tank behind the pilot.
Only four Minimoas remain airworthy: two in Germany, one in Japan and the latest one to fly in the U.K.
