I just replaced a faulty servo in my Blade, and the tracking seems kinda off. I have the pitch as close as possible to 0 and 10 like the manual recommend. The tracking seems off at full throttle/collective when I have the skids clamped down to my workbench. Just for good measure, I replaced the feathering spindle with a new known good one. It tracks fine at about 75% throttle, but full throttle one blade will track higher. I've tried turning the ball joints 1/2 turn per blade which is the minimun adjustment, and it still won't perfectly track at WOT. Any ideas? Oh, these are flat bottoms.
