The first DA-6, registration N9146Y, was built by Leeon D Davis in 1981. DA-6 and later use the USA 35B airfoil modified with a flat bottom.

The DA-5A single-seat, low-wing monoplane makes use of the same V-type tail as the DA-2A. The pilot sits inside an enclosed canopy behind a 65-hp Continental turning a fixed-pitch prop. Both the wings and fuselage are alight alloy structure with stressed skins, and the landing gear is the non-retractable tricycle type.

Many DA-5 and DA-5A aircraft have been built from plans. DA-1 through DA-5 used the Clark Y airfoil.

In 1966, the Davis all-metal design was voted the most popular at the Rockford EAA Fly-in. It requires little work on the part of the builder because of its simple construction, with no compound curves or ex-pensive fittings. The Davis design uses the 100-hp Continental and is one of the few do-it-yourself planes with a V-tail. Of low-wing, two seat side-by-side and nose undercarriage. The prototype DA-2 nosegear used a spring instead of rubber doughnuts. Engine range 65-100 hp.

Many DA-2A and DA-2B aircraft have been built from plans. DA-2A scratchbuilding plans describe both DA-2A and DA-2B versions. DA-1 through DA-5 used the Clark Y airfoil.

The DA-4 was completed as DA-2C. The DA-4 was intended as the production version of the DA-2, but was sold unfinished. Brent Hughes finished it as DA-2C N26146. This should not be confused with the D2C “Bandit” mods.

The Davis DA-1 was a light aircraft designed in the United States in the 1950s which never progressed beyond the prototype stage.

Leeon D. 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 a V-tail.

Wings and tail surfaces of the DA-1 used external heat treated ribs; those surfaces were of constant chord. DA-1 through DA-5 used the Clark Y airfoil.

Power for the DA-1 was a horizontally-opposed Lycoming O-360 of 180 hp (134 kW), which gave a top speed of 125 mph (201 km/h).

Registered N5822N, it was first flown on 24 May 1958, initial test flights showed that there was not enough elevator authority with full flaps, and the plane was very loud. Soundprofing, and aerodynamic modifications were applied. Davis tried to bring the plane to market as a certified aircraft (his goal was a selling price of under $10,000), but was not successful.
