Aero A.34

From Wikipedia, the free encyclopedia

The Aero A.34 Kos (Czech: "Blackbird") was a small sports and touring biplane built in Czechoslovakia in the 1930s.

It was designed in 1929. The design was similar to De Havilland Gipsy Moth. Of conventional biplane configuration, wooden construction, it featured wings that could be folded to allow it to be towed to and from airfields by automobile (width 2.91 m).

A prototype (registration L-BASO) had a radial engine Walter Vega 85 hp. It took part in the Challenge 1929 international contest (pilot Josef Novak), but had to withdraw due to engine failure and crash landing on August 8, 1929. Seven A.34s and its variants were built, with different engines: three A.34J had engine Walter Junior and three A.134 - Walter Venus 110 hp. They were used as trainers and sportsplanes in Czechoslovak civilian and military aviation.
