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?
