After replacing, I rotated the motor by pressing throttle, it was smooth at first then I hear a clicking sound from it and I can feel the motor vibrating. Please help troubleshoot the problem.
From the video:
- At first, I pressed throttle lightly and quick, you can hear the clicking sound clearly.
- Then I pressed continuously, you can hear the clicking sound in the background.
