Aeronca E-107


The Aeronca E-107 was one of the first low-cost reliable engines of the post-World War I era.

Design and development

The E-107A was a production aviation flathead 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, but with all versions having air-cooling fins atop the cylinder heads, similar to many air-cooled two-stroke engines in appearance. A Winfleld Model 5 carburetor was standard for the engine. The E-107 was replaced by the uprated, overhead valvetrain E-113 engine based on the same design.
