OS FSa 81 Four Stroke New. (CODE 482)

This engine was mounted in a plane but was never started or used. This is a high-performance, ringed four-stroke. I personally fly one of these engines and they are very efficient and light on fuel with the velocity stack on the carb. This engine also featuring a unique lubrication system that eliminates the need for crankcase breather.
