RE: Sig SE CG
You will probally be ok where you are as the SE will fly a little tail heavy but why not get a larger motor for the front. That is what I did with my first SE that was tail heavy and I will never go back to the recomended engine size. The extra power just puts in a class by itself. It will be much faster and will get you out of trouble quicker so you can fly lower and do more than ever before. Engines to consider 61/91 two strokers Saito 91/100
