I have a question regarding prop size. I have an os 120 and broke my 17x6 APC prop that has been doing great. I went to our local hobby store and all they had were 17x8 competition props (APC). Not sure if there is any significant difference or not. It seems to me that I recall a discussion on props buried either in this Venus thread or another that said 17x6 was the max with this engine/plane combo and 17x8 was too much prop.

Thoughts any of you people?
