Thanks everyone for ALL your suggestions!!!! I am on somewhat of a budget, that is why I was considering a 2 stroke over a 4 stroke. As I mentioned in my original post, this engine will be going in a Sig Clipped wing Cub (1/6 scale). I flew one of these back in the early 80's with a K&B 40, WAY too much power!!!!! So this time, I would like to have a smaller displacement up front. Also, a 4 stroke would be a lot heavier, I am concerned about it being nose heavy. If I remember my original version, it was nose heavy (a little) with a K&B 40 up front.

Is the Evolution (.36) a good engine? I have not heard too much about them.
