RO Jett 65RE Prop

Anyone using an RO Jett 65 RE? I have one just broke in and now going to the next stage - into the stunt ship.
I would like to use 3 blade Brian Eather. I was thinking of 12 in x 3.75 but some have told me 13 x 3.75 would be better. Anyone with some flying experience on this engine?

I don't have a 65, just a puny 61 , but I have been using a 12.5-3.9 flat-back 3-blade. It will undoubtedly spin more prop if you are so inclined. Could also ask the maufacturer, AKA Maverick.

I am currently using an Eather 12" 4-blade on mine. I am currently using 4.25" pitch. I am trying different tank setups and other trim adjustments, and it is possible that I may have to slightly change the pitch in the process. My current tank setup gives me a lap time varying from about 5.63 sec at takeoff to about 5.35 right after the clover, assuming a 10,400 launch rpm. Pipe is set at exactly 18" per Richard's recommendation. Plane is a UHP Bear Nobler, maybe just a little on the heavy side. I have both the 12.5" 3-blade wide and narrow, but I have not tried them yet. I'll mess with success after the contest this weekend...You're gonna love that engine!
