the thing is, when you tilt it to extreme angles a little vibration is normal because the gimbal is in its limits, its not realistic. BUt when it starts to vibrate in normal angles something is wrong.When I hold the P3 by the legs and rotate to one side, the gimbal starts to pulsate or vibrate. I tried a gimbal calibration but that doesn't do anything. So does this mean turn it in? Sucks, getting ready to fly off to Hawaii.
