Frenchie, thankyou for your words of wisdom. After talking with my LHS, I will be going the pro 46 route. They are selling the engine for 107 and the 42 for 82. I will spend the extra 25 for the better carb and track record for the 46. I suppose once I learn the basics of running a nitro engine, then I can make more educated decisions then what I can now.

For four strokes, are OS and Saito the cream of the crop or is it just advertising that makes them sound that way.
