Best Propeller for OS 61 FX

Hi,
I`d like to know what is the best propeller to make this engine hit its highiest thrust.
Can anyone tell where I can find its power chart(Power/RPM)?
Is there some efective carbon fibre propeller for this engine?

13x4 should produce about 13 # of thrust in level flight.

MikeSell has done extensive research on this motor. I know his son used a Bolly CF prop for SAE aerolift, and a Bolly Clubman for practice. try a PM to him for specifics.
