Skorman, I used the 13x6 to do the break-in and everything seemed real good to me. Now remember this is my first 4 stroke so I dont know if this will be the best fit or not right now, but I will play with it some once I start to fly it and check other props as well.

Fadi81, thanks for the information I will pick up a 14x8 today since I am going to a rc hobby show near me. It is not a huge show, but they have alot of stuff their that I can not live without.
