Davis DA-1
The Davis DA-1 was a light aircraft designed in the United States in the 1950s which never progressed beyond the prototype stage. Davis tried to bring the plane to market as a certified aircraft, but was not successful.
Design and development
Davis constructed his DA-1 starting on 24 April 1957. It was a strut-braced high-wing single-engine all-aluminum airplane designed around the new Lycoming O-360 engine. The fixed-nosegear-equipped piston-engine DA-1 was of otherwise conventional configuration, but its V-tail was similar to that of the contemporary Beechcraft Bonanza, whose high cruise speed was attributed partly to its use of that empennage type.Wings and tail surfaces of the DA-1 used external heat treated ribs; those surfaces were non-tapered.
Power for the DA-1 was a horizontally opposed Lycoming O-360 of 180 hp, which gave a top speed of 125 mph.
