Primary trainer NV-5bis, slightly re-designed for series production. Engine - mass built M-11 with metal propeller. Fuselage structure - simplified. Wing airfoil TsAGI-876 (flat underwing surface) instead of Hettingen-476. Ailerons and tail controls got duralumin frames and rigid control rods.
Factory and State trials involved about 60 pilots, everyone was satisfied. Mass production was planned, but only three prototypes and four pre-series aircraft rolled out.
In 1939 improved MG-11F engine was installed on strengthened U-5 and it became U-5bis. One experimental and four pre-production U-5bis were built. Despite it was an obvious success, it failed to compete with U-2 and UT-2, which already were in mass production.
