Exhaust through the head, the engine kalilny, can beat and gasoline.
Perfect for cord copies or radio models.

Turns 1 crankshaft to 12000 in min.
Turns 2 crankshafts to 19000 in min.

Traction with six-blade propeller 14 kg.

So from what I can pick up, it is piston port induction, bevel gear overdrive. Some interesting exhaust port on the head that I have never seen. Nicely made! F2B stunter, but has a throttle for other apps? 2CC maybe 2.8 and prop size might? be 206 to 208mm diameter. I played it at half speed and got the wife to translate. She doesn't really know Russian but got a few words.

very cool, I would like to have one those, but I would have to have the twin cylinder

cooling may be a problem
