Belford Maule dropped out of school to apprentice himself as an auto mechanic. Shortly after he got his first taste of aircraft as a motor en-gineer on Army dirigibles. Deciding he should learn to fly, he built himself an airplane: the M-1.
Built around 1930-1931, this homebuilt plane was powered by a 27 hp Henderson motorcycle engine. It flew both as a taildragger and as a floatplane.
