Motor quality and stability

Does anyone have any experience with motor quality as related to multicopter stability?

I'm wondering how much the quality of the motor has to do with the stability of the copter?

	Less than in a normal Heli. Its more the Motor mount, and the way it plays together with the Motor. Having the Motor on long Arms, ( thats naturally no problem on small carbon frames) could cause the motors to oscilate, caused by their vibrations. As a result => the better the Motors are ballnced, the better the bearings and the stiffer the Arms of the Multicopter, the better it will fly. Furthermore - a small powerfull motor will spin up faster than a less powerfull, bigger (cheaper ) motor, meaning the better motor will react faster on throttle change = Stability and controlls.
