Russian "Berkut" light helicopter

[Stargazer]

The "Berkut" is a little-known small bubble-shaped Russian helicopter with contra-rotating rotors and an H-tail.
The basic version uses a 147hp ConverVAZ engine, while the "Berkut-M" uses a 150hp Lycoming for a slightly better performance.
I haven't got any more info on this helo, but the photos suggest at least two were built. Does anyone know more?

Do I really see the exhaust pipe outlet just above the heat exchanger/carburetor inlet... That under a contra-rotating rotor?!!
(otherwise it looks a fine little piece of engineering)
