Aircraft was built as a single-wheel Flying Wing glider.It was decided to install rocket engine OR-2 (under development by F.A.Tsander), and project was designated RP-1. In mid-February 1932 aircraft was transported to GIRD, and on February 22 was flown by S.P.Korolev (as a glider).Osoaviakhim funds for the rocket-propelled aircraft were allocated on February 25.

S.P.Korolev flew it also during IX Glider Competitions in 1933.

OR-2 was delayed, and BICh-11 was flown with 27hp "Scorpion" engine. It was one of the first powered flying wings ever to fly. Unfortunately delay of the rocked engine was too long - "warranty" of wooden glider expired before the OR-2 could be fitted on it.
