BICh-20 'Pioneer' by B.I.Cheranovskij

72k b/w BICh-20 on skis, "History of aircraft construction in the USSR", Vol.1 p.568

Very small flying wing, with enclosed cockpit incorporated into tailfin. Wing was almost triangular, elevones and ailerons had inverted airfoil. Landing gear was non-retractable, skis used for winter trials.

Trials revealed good stability and response in flight envelope. Thanks to large fin, BICh-20 was very stable on takeoff and landing. Trials were performed with two types of light engines.
