I have an OS 45 that has delrin vent and needle valve assembly that I have had sitting around for many years. It was a gift from a friend. Is this engine ok for stunt ? If so how much rework is required ? Thinking of putting in the on-line build plane.

many people used that motor with great success, It does however Have to be loaded properly, this means run a 12 or 12.5 inch 4 to 4.5 pitch prop or a 12 x 4.25 3 blade. If you run a 5 or 6 pitch prop on the FSR you may get some serious wind-up in the wind
I would use a 275 venturie with a standard 157 diameter ST or PA NVA

I checked the engine last night. (OS 45) Havent turned it over in long time, now it wont turn over. Didnt want to force it so I left it alone. Will send the engine so you rework it. Do you have a cost on this one ?
