Development and design
The Davis D-1 was developed from the Davis V-3, which in turn was developed from the Vulcan American Moth. The Davis Aircraft Corporation had its factory at Richmond, Indiana. The D-1 is a parasol-winged aircraft of mixed construction with a two-spar wing and a rectangular welded steel-tube fuselage, the whole being covered by fabric. There are tandem open cockpits and it is fitted with a fixed tailwheel undercarriage which is attached by struts to the fuselage top and bottom. The wing is braced by struts from the lower fuselage. Various engines of between 60 to 125 hp (45 to 93 kW) have been fitted.[1]
Operational history
The D-1 was used from 1929 by sporting pilots and by private pilot owners for leisure flying. In September 1930, Art Chester bought a Davis D-1-85 parasol, and flew it to victory in the 1930 National Air Races.[2] Most were sold in the United States but at least one went to Argentina. Fourteen examples remained in 2001 in various states of airworthiness[3] and several are still airworthy in 2011.
