Huntington H-12 monoplane

The 1920 Huntington H-12 monoplane was a successful design powered with a motorcycle engine. Designed and built by Dwight Huntington of Hempstead, this was the first kit, or plan-built, lightplane professionally engineered in the United States.

With a wingspan of 20 ft, the wings were attached to the upper longerons, but downward vision was increased by windows in the sides of the cockpit. It was powered by a 15 hp Harley Davidson motorcycle engine.

Able to cruise a 60 mph, plans of the H-12 were sold through aviation magazines into the late 1920s.

The cost of construction, without motor, was well under $80.
