After I crashed my motor started making a weird noise when i turn it manually and the motor hub looks like it has shifted away from the center. Is there any way I can fix the motor or do i have to replace it?
Remove the motor bell and place a screw driver through the bearings and roll the bearings with the shaft of the driver. They should be totally smooth. And have basically no noise. Another way is to remove the props. And turn on turtle mode and move the right stick towards each corner which will spin up one motor at a time. And listen for any grinding or popping sounds. They should be totally smooth. Just a whining sound of the motor rotating.
