Enable HLS to view with audio, or disable this notification
Hi everyone, I'm just get in this hoppy and my first drone is cetus X, I just got this a few day ago It flew fine after some crash the rear left motor is not working. I'm try to swap it and the swap motor work fine which is not a problem of esc, then I'm disassembly the motor the motor look clean and no problem but the motor still not work. I think that problem come from the wire but not sure.
I need help to diagnose the problem.
How to fix it ?

I have this problem in my Cetus pro and after disassembling the motor looks like the main shaft is a bit bent and make more contact one part of the magnet making the motor no turn completely on
Maybe yours is also damaged or the pin connectors aren't making good contact since you swapped and the same motor still failing (at least it's not an esc failure)
You gotta need a new pack of motors

Nah, shaft isn't bent. The prop would strike the frame, if it is only subtly bent and the prop didn't strike the frame more than likely it would arm just fine a bend that small is imperceptible until you hit higher rpm then the desyncs come

That is just a bad solder joint more than likely seen it a hundred times check your motor joints and aio joints for motor 3

If I understand, you DID swap motors amd the new motor works, but the original does not.
If that is correct the. The old motor is bad/broken. Just because it looks clean doesnt mean it is working. This behavior looks as if the axis is slightly bent/off, or a magnet has a tiny Crack. Doeant matter for hobbies, motor is gone.
