==Design and development== The 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.<ref>{{cite journal|journal=Air Progress Sport Aircraft|date=Winter 1969|page=70}}</ref> 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.<ref>{{cite web|author=www.jrwebworks.net |url=http://www.stewartaircraft.com/main.html |title=Stewart Aircraft Michigan |publisher=Stewartaircraft.com |date=1962-03-28 |accessdate=2010-05-31}}</ref>
The design was inspired by the Demoiselle by Alberto Santos-Dumont.<ref>{{cite web|url=http://www.airbum.com/pireps/PirepPeanutHeadwind.html |title=Stewart Headwind |publisher=Airbum.com |date= |accessdate=2010-05-31}}</ref> The fuselage is triangular sections of welded tube steel covered in fabric. <!-- ==Operational history== -->
==Variants== A Volkswagen air-cooled engine was the only engine specified for this model, however many examples exist with alternate engine installations.
