Hi! I have a bit of a loud noise when I start-up my hexa and upon examination looks like the outer barrel of the 880kv motor may have moved up creating a slack with the internal part of the motor.Not sure if I'm making sense but if you push down the outer rotating drum vertically, the clip at the bottom of the motor shaft separates from the base of the stationary part of the motor. SO with rotation, the motor tend to go up and the force with which this happen and then suddenly prevented by the clip at the bottom causes the sound. Tried remedying the situation by removing the set screw on the 880 that holds the shaft to the outer drum and tried pushing down the drum by "pounding" on the shaft. It didn't solve the problem though. Im afraid, one of these days, the force of rotation will overcome the clip at the bottom and not only will I hear the elevated sound but the entire external drum together with the propeller will fly off and cause a crash.
Also, what is the shaft-outer barrel of motor set screw hex size. I can loosen it but having difficulty tightening it as the hex I'm using somehow slip when tightening?
Any thoughts on the matter will be much appreciated.
