Hi everyone. I flew my F450 a lot this weekend and had good luck with it in both calm and windy conditions. Right before I came home yesterday from the field I had a minor flip over and bent up a prop. I changed it and did a very short FPV flight but the picture was cutting in and out due to the crash knocking a connection loose. I flew it this afternoon and it was a lot less stable. I also noticed if I yawed one direction that the back left arm would drop slightly. I switched the back motors and now when I yaw the opposite direction the back right side will drop. I am assuming that the motor on the arm that is dropping is bad and maybe not spooling up as fast as the one opposite it causing it to drop. I am 99% sure that the motor is causing it since the arm dropping followed it. I already ordered some replacements but figured I would check with you guys to make sure there isn't something else that could cause this. Is an arm dropping during yawing typical of a bad motor?
Bad Motor?

I hold the arm under the motor in question and spin em. you shouldn't feel anything. these motors got really small bearings and the prop adapters being part of the barrel makes em one time crash motors if they get damaged. usually you'll see a ding/gouge/scratch in the bell. there are no parts other than bearings from places like boca
Yeah, I've taken it apart and can't find anything wrong with it visually and the bearings feel fine but when I turn it it the "cogging" feels a little rougher than the other motors. Can't see anything rubbing but something isn't right with it. I actually found some bearings the same size and replaced them but the problem persists. There was a little dirt in the motor after the crash but I cleaned it all out. Anyway, I'm going to put a new one on and see what that does.
