== Development ==
Chyeranovskii's smallest aircraft was the BICh-20 Pionyer, following broadly similar lines to its predecessors, the airframe was constructed of wood with a low aspect ratio tapered wing carrying suspended ailerons and flaps at the trailing edge. The engine and pilot were accommodated in the central nacelle with the cockpit canopy forming the leading edge of the broad chord fin and rudder.
Flight tests were carried out, with ski undercarriage from early 1938, to investigate the turning performance of the tail-less designs, particularly in flat horizontal flight without banking. Tests demonstrated turns up to 35 deg while the wings remained horizontal. The initial 18 hp Blackburne Tomtit was replace with a 20 hp Aubier-Dunne in the latter half of 1938
