Hi guys. I have a brand new M15 straight out of the box with the latest firmware. It was properly balanced and it was autotuned properly. It works and reacts just the way I want it except that when I roll it about 40 degrees, the motor gives and it goes limp. The pan and tilt holds and works fine but the roll gives when I roll it about 40 degrees or so. Yes, I'm never going to shoot it like that but this is for testing purposes. I have tried the M5 and the M10 and this hasn't happened before. Any ideas?
