Default OS 55ax

Whats the ideal RPM for an OS 55ax?? With a 12-6 prop I'm @ 12,750.

Mid-to-high-12,000's is a good place for full-throttle RPM on the ground when leaned to just rich of peak RPM. Your RPM looks right.

How about 11K +/- using a 13x6? Or would you consider that too much prop for the .55?
