Development

After the relative success of Cheranovsky's first tailless gliders, the BICh-1 and BICh-2, he continued the tailless theme with the BICh-3. The BICh-3 was built of wood with a parabolic wing having a straight trailing edge. A central nacelle, containing cockpit and engine, was faired into a large and powerful fin and rudder. The undercarriage consisted of a trousered central mono-wheel with wing-tip skids. The BICh-3 was flown in Moscow in 1926. Tests found it to be unstable, so consequently the handling was improved, after minor modifications, enough for the aircraft to be reassessed as safe to fly.
