I prefer the sound of a four-stroke especially in scale or semi scale models but I have some two strokes in sports models.

If your four stroke engine has compression, if the valves are opening and closing at the correct time, if you've got a good glow-plug of the correct heat range and if you are using the recommended fuel and the correct sized propeller, there is no reason why your engine should not run.

The OS 40FS is a little jewel and will suit a small scale, sports or old timer model.
