The motor is fine and the drone still flies but it’s exposing a circuit board that leads to the motor. I’ve looked on YouTube and there’s a video on how to do it but you have to take all the wires off and rebuild, it then involves soldering the wires back on, it’s a bit out of my league I think. I’ve looked at stuff like drone doctor but I’d rather stay away from having to send the drone off to be repaired, in fairness to the drone manufacturer they are sending me a replacement arm out for free.
