ha ha i love 2 strokes though.. from bikes to go karts etc. all my shyte is 2 stroke Nothing like raw 2 stroke power band lol but were not talkin cars and bikes now lol so i'm sitting on the fence, not sure which way to fall. I think your right tho, the 4c is better for all round aerobatics, because of the low end power.. i can't see a two stroke regardless of size doing much in the way of low speed aero?
