Development
editTo compete in the August 1941 Osoaviakhim all-union air race Chyeranovskii followed the successful recipe he used in the BICh-20, building the smallest possible aircraft to house the Renault 6 in-line MV-6 engine and the cockpit in the leading edge of the fin. The inverted gull wings allowed a shorter, pneumatically retracted tail-wheel undercarriage, to be fitted at the junction of the inner and outer wings. The aircraft was completed in 1940 but flight tests were not carried out till June 1941.
The BICh-21 was a firm favourite to win the all-union air race but Operation Barbarossa intervened, with the start of the Great Patriotic War, further work on the BICh-21 was stopped..
