The BICh-3 (Russian: БИЧ-3) was a tailless research aircraft designed and built in the USSR in 1926.

After Cheranovsky's first tailless flying wing gliders, the BICh-1 and BICh-2, he continued developing the concept with the BICh-3. The BICh-3 was built of wood with a parabolic wing having a straight trailing edge and a curved leading edge. The cockpit was faired into a large fin and rudder. The undercarriage consisted of a faired central mono-wheel with wing-tip skids. The BICh-3 was flown in Moscow in 1926. It was found to be unstable in initial tests leading to modifications that improved the handling sufficiently for it to be cleared as safe to fly.
