Design and development
editThe first Headwind was flown on March 28, 1962. It was one of the first aircraft to fly in the United States using a VW engine. The prototype flew with a Huggins VW conversion.[2] To use a standard propeller, a patented PRSU (propeller speed reducing unit) was developed to keep the engine RPM high and propeller RPM at its optimum speed.[3]
The design was inspired by the Demoiselle by Alberto Santos-Dumont.[4] The fuselage is triangular sections of welded tube steel covered in fabric.
Variants
editA Volkswagen air-cooled engine was the only engine specified for this model, however many examples exist with alternate engine installations.
