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.
