Just a gentle reminder to Arducopter pilot that want to use AutoTune feature and has SimonK ESC on large multirotor.
SimonK ESC are prone to "out of sync" issue especially with pancake motor with high number of pole. Meanwhile Autotune feature in Arducopter 3.1 software are testing the PID control system quite aggressively, there are few copter crash due too this. So if you have the above configuration, I suggest do not use AutoTune feature.
