I have been flying single propeller RC planes for many years so I know the advantage and necessity of balancing props. But coming from the plane world, I don't have much experience in the way of multi-rotor aircraft. I follow the same steps that I always have where I sand until the one side of the propeller is perfectly balanced to the other (less worry about the hub, but I do check that too from time to time).
A question for those that have flown multi-rotor aircraft for a while, is it necessary to balance the propeller against the other three? If you are sanding a fine amount off of one, it now has a slightly different weight and shape than the rest. Do this put extra stress on one of the motors (or the other three) and does this affect flight or the camera at all? I have not noticed any issues thus far and quite frankly the Phantom itself is not exactly balanced itself (which I assume is what the IMU calibration determines)...
