I made another attempt tonight, made sure it wasn't binding, I have a little bit of RA backlash but not a lot. I made sure it was well balanced and tried increasing the pulse duration but nothing really seems to help..

I'm not sure I understand what's happening. Is the RA motor trying to drive in reverse but not able to due to resistance? But wouldn't I hear the motor skipping/stalling if that's the case? I don't feel like backlash is a possible cause here. I did some testing with the hand controller before going out and when setting rate to 2 I can change direction more or less instantly. And it worked before when the backlash was a lot worse.

I was planning to see if I can run PHD2 standalone or some other software to see if I have any similar issue.
