Have narrowed it down to 11" props. Both MA and APC 11x7 seem to be the best right now. Balance point is about 1/8" behind what was listed in the manual. Flies very neutral in knife edge and very little down required when inverted.

Will be trying some 12 " props, but think the 3.75" will slow the plane too much and require me to run full throttle most of the time.
