I can't get around that problem, that immediately after the apm2.0 boots up and finishes initialization, the motor starts spinning.

TX is in manual mode. "Nudging" does not work, TX has no effect on motor or servos when the APM2.0 is in this weird mode after bootup.

After I switch on the TX to any mode (stabilize in the video), the motor stops spinning and keeps off even when I go back to manual mode.

Here you can see the problem:

I uploaded the firmware again and reset all the parameters, initialized the TX and set all the modes. Nothing seems to help.

Thanks for any suggestions!
