225:, United States. It is a single-seat, single-engine, all-metal airplane typically powered by a 1/2 VW engine in the 32 hp-45 hp range although other engines have been used successfully. It is built from plans, but many of the components are available pre-made from Hummel Aviation. Examples have been built for less than $ 4,000 with extensive "scrounging", but with all new material and a pre-built engine, a more likely figure would be $ 8,000–$ 10,000.

The standard location of the fuel tank is forward of the instrument panel. Some builders have moved it to the leading edges of the wings. By creating a sealed leading edge tank, the fuel is moved away from the pilot for better crash survivability with the added benefit of more than doubling the fuel

Windwagon plans as well as Hummel's modifications and try to incorporate the two. This proved very difficult. One of those builders was Bill Spring. An engineer by profession, Spring took a great many photos and consulted with Morry Hummel until he had the complete

In the fall of 1979, Morry Hummel, who worked in the Curtis Wright experimental department during World War II, purchased the plans for Gary Watson's
Windwagon and the development of the "Hummel Bird" began. Because of the weather in Hummel's state of Ohio, a canopy was needed. The
