I have a BME 30% Yak, 8611's, Dubro HD stuff, CF rods, ball links on servo end. I need some procedures/ideas on how to setup these so that all three rates are equal on each side.... When I set High rates, matching both ATV end points, then my lowest rate isn't exactly both down/up...If I tweak ATV to minimize differences on LOW rates, then the others have errors.

I have already done most of the usual things, just would like some procedures/ideas from others who have had to solve this in case I've overlooked something in my setup.

BTW - I am not troubled with RATE of deflection, that's fine between the two servos.
