Best speed prop for a 91 FX
I have a Bobcat 50 (51 in wingspan) that had a 61FX on it. I was not happy with the speed of the plane and I replaced the 61 with a 91. (FX) They are the same size as far as actual outside measurement and weight. Problem is, the 61 was swinging a 11-8 and that is close to the biggest diameter I can get. Maybe another inch. Question I have for you guys is what prop would you recommend? The plane is not really aerobatic so I would at least like to make it quick. Got to have some fun with it. The 91 is brand new, never ran, and is completely stock. Muffler carb and all. Any help would be appreciated.

No one else seems to know either, so I will guess something with oversquare like a 12-12 or 12-13" I am not into the 90 size but somewhere around that? maybe? I am sure other wiser folk would know more.
