BICh-7 by B.I.Cheranovsky

fter success of the BICh-3 flying wing B.I.Cheranovsky started several other flying wing aircraft projects. One of those was BICh-7, up-scaled single-engined aircraft with open cockpit. It carried two small rudders (without any fins) on the wingtips.
Landing gear was similar to the BICh-3, with single main wheel and three support skids. This time it became a failure. BICh-7 turned very sluggish on takeoff, rudders had little effect.
After few takeoff attempts (not all were successful!) it was rebuilt into the BICh-7A.
