TsKB-27/SR/R-9 -
Advanced design of high speed recconaissance monoplane, tested in 1935.

unsuccessful mechanism of gear retraction. Attempts to bring aircraft into
production "on any price" killed the project - next modification (R-9)
had fixed landing gears and lost contest with Neman's R-10
Modifications:
R-9 -

mechanism of the last one and rush to come up with new design killed the
progressive project - R-9 had fixed landing gear, providing huge drag.
It lost a conest with Neman's R-10. Armament:
2g20mm, 3mg7.62mm, bombs 400kg.
