Status: offline 		Just bought one of these in a 38% Christen Eagle. Right now it has a 22 X 12 Zinger prop. Anybody have any numbers out there? I was getting just over 6,000 rpms w/ some pretty old fuel. I got fresh fuel now, but haven't fired her up yet to check. I am also thinking of trying a 24 X 10 prop after I get a couple of flight in just to compare.

Thanks guys!!!
