Aeronca E-107 / O-107
The Aeronca E-107 was one of the first low-cost reliable engines of the post-World War I era. A flat-twin aircraft engine designed by Ray Poole and Robert Galloway, the E-107 first ran in 1929.
The E-107A was a production engine designed to replace a Morehouse engine on the first prototype of the Aeronca C-2. The first five were produced without cooling fins on the crankcase. A Winfleld Model 5 carburetor was standard for the engine. The E-107 was replaced by the uprated E-113 engine based on the same design.
The major application for the E-107 was powering the Aeronca C-2.
