Thanks for the info with the Moki and prop combos. I am pretty content with the performance so far, but I have not tried much in the 3D arena with my setup yet. Vertical climbout seems limited, as in the plane is decelerating uphill rather than continuing to the moon. The book lists 7000-8500 on the ground and up to 10000 for max speed. I know that I'll never see that much with this size prop, but I think 7000 is a bit low. I will try reconstructing my fuel system for a bigger clunk and wider fuel tubing.

Thanks guys!

MRMcFarland:
Right thrust seems right on. I give very little rudder input during take off.
