OS GF 30 Four Stroke Petrol

It's a four stroke. It's a petrol with all the cleanliness and economy that comes with it and it's an OS. Not a lot to dislike here!
The GF 30 is the engine for models that were previously operated with 120 to 150 glow or 20 cc petrol engines. The realistic sound makes the engine ideal for scale, aerobatic and sports models. The engine impresses with its high torque and low fuel consumption.


Supplied with ignition unit and silencer.


A superb engine that will give years of trouble free life. It is after all an O.S.!
