Sorry about triple posting but Tower says for sport models my engine should use a 12x6. I would like to get more verticle power so I should use a 13x5, right? You get bigger diameter and less pitch I think. And for more speed I would get an 11x7 right? Please correct me if I'm wrong because I want to get several props when I pick up the engine. Also GMS engines have no break in instructions so if you guys could tell me how do that it would be great (I never broke in my last one and it took a long time to get working right). I think you are supposed to use a smaller prop for break in also, so I will get an 11x6 or 11x5 too. The engine should be in tomorrow I believe.

PS. I got a new signature! check it out.
