Help with Motor Issue

[xzlr8]

Motor sputters and led underneath does not light up. Oddly when I loosen the screws holding the motor a bit it corrects itself after a few seconds. Any ideas?

The motor sputter and LEDs not turning on is an indication that the ESC in that arm is bad.

If that thing ever had the prop guards installed, and the same screws were used after removing them, then the motor could be damaged as those screws are too long and can go up into the motor and hit the windings.

I just had the same problem and it turned out to be a bad motor. My LEDs would light up on the initial startup but when I turned the motors on the one didn't light up. Tested by swapping with a working motor and the problem followed where I put the bad motor.

Wanted to let everyone know that it ended up being a bad motor. Replaced it and good as new.
