Got a bit more flying in today, and some fine tuning. The verdict is the motors running pretty decent now, not perfect, but pretty good. I will probally try out the uniflow setup next to try and make it better yet.

Interestingly, I gave a 11x3 apc prop a shot, and I think I like it better than the 12.25x3.75 prop. While thrust is down a bit, theres still plenty to do pretty much anything, but what makes it nicer is the motor responds faster I thnik from a combination of the prop being lighter and easier to rev, and the lesser load also allows it to rev into a higher hp rpm range before the prop really starts to load it down. The net result is the throttle response seems snappier.

More experiments to come.
