G-23 and G-23bis by V.K.Gribovskij

G-23 was built as a testbed for GAZ-M-1 (GAZ-M-60), car engine modified by E.I.Agapov in 1935. Aircraft construction was similar to the G-22. Radiator tunnel - under the engine, steel propeller.
Trials at NII VVS (until February 26, 1937) proved controversy of the engine choice: poor climb rate, reasonably good speed and very good reliability. Engine was twice heavier than aircraft engine of same power, and aircraft could not be used as an aerobatic.
During July 24-27, 1937 pilot I.Grozdiansky on G-23 made 'endurance' flight Tushino - Kharkov - Zaporozhje - Kacha - Zaporozhje - Kharkov - Oriol - Tushino, covering 2584km in 21h.
The second built G-23 was powered with M-11E (1938) and designated G-23bis. With lighter and much more powerful engine, G-23bis was a great performer. Two international records were set:
