This dedicated free flight engine was made in the Ukraine and is reputed to be quite powerful, especially when piped. A head clamp ring is used to retain a custom glow button, which forms an integral head and squish-band. This can be replaced by a head and squish band assembly that is tapped to take Nelson plugs. A built-in brake, prop driver and spinner are standard. A flood-off inlet nipple and pinch mechanism are fitted on the left side of the venturi and there is a cowl hold-down immediately behind it. Evgeni Verbitsky used these engines on his early F1Js.
According to Vasily Beschasny the engine is no longer available and the manufacturer is no longer in business.
