The Stewart Headwind JD1HW1.7 and SAC-1VW is a single-seat high-wing tube-and-fabric construction homebuilt aircraft.{{cite journal|journal=Air Trails|date=Winter 1971|page=76}}

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.{{cite journal|journal=Air Progress Sport Aircraft|date=Winter 1969|page=70}} 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.{{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}}

The design was inspired by the Demoiselle by Alberto Santos-Dumont.{{cite web|url=http://www.airbum.com/pireps/PirepPeanutHeadwind.html |title=Stewart Headwind |publisher=Airbum.com |date= |accessdate=2010-05-31}} The fuselage is triangular sections of welded tube steel covered in fabric.

Variants

A Volkswagen air-cooled engine was the only engine specified for this model, however many examples exist with alternate engine installations.
