Try a 10 x 7 and/or a 10 X 8 APC and see which one you like better. Are you using the stock muffler?

I have a Webra .50 with a Nelson muffler and APC 10 X 8 and it hauls it along quite respectably.

the Os 55 is a torque engine , not an RPM race engine. Step up to an 11x8, or a 12x6, the 10 inch props are best left to the 46's so the can get to R's out of them.

Skull pretty much nailed it. More pitch, less diameter where you can. That engine develops its torque and power at a lower RPM than it's little brothers. Use that to your advantage!

I run an APC 11x8 on my OS 0.55. That is a good starting point.
