Motor esc glitches. Crashes flips out of control.

1806 motors. 12a simonk escs.. cc3d. Carbon frame. I've built 3 now and they all seem to have motor glitch and lose control at random. Seems as tho the escs are falling out of sync with the motors.

I found the problem was a bad motor-esc sync. I needed to do nothing but calibrate them differently. In the openpilot gcs I was waiting too long hearing the beeps while calibrating the escs. I tried it during the second beep, which is usually a double, then dropped the throttle to calibrate. If your familiar with the op gcs youll know what I'm talking about when you get there.
