New project.... This model, in 1/100 scale, is available as a free download from Minimodel, Czechoslovakia.
The subject is the BH-1 sports plane, a single-engine aircraft from 1920 (the first from the Czechoslovakian company Avia).
The BH-1 was a low-wing, braced, monoplane of wooden construction, with tailskid undercarriage. Power was provided by a Daimler engine, which actually proved inadequate to fly the aircraft with both seats occupied. It was rebuilt in 1921, with a Gnome Omega rotary engine.... The more powerful engine enabled the aircraft to be flown two-up.
