label: Summary
content: Aeronca (Aeronautical Corporation of America) built the first widely accepted light planes in the U.S., the Collegian. These were originally powered by an engine based on a Harley-Davidson motorcycle engine, the Harlequin. To overcome limitations of that engine, Aeronca designed its own engine, the E-107, and that engine proved inadequately powered for a larger aircraft.
label: Summary
content: Certificated in April 1931, the Aeronca E-113 was an outgrowth of the Wright-Morehouse engine and was designed again for light aircraft. Considered highly reliable, it was the most powerful two-cylinder engine of its time. The E-113 first powered the Aeronca C-1 Cadet aircraft in 1931. It was also used in the Aeronca C-2 and C-3 aircraft. The C-3 was widely used for student instruction in the 1930s.
