Just got my new toy and it's waiting for its first flight. There is a little bit of gimbal noise when the quad is powered and stationary (a low level constant buzz which I can hear as it's indoors). The noise level doesn't change when I move the P3 around. It does get somewhat louder at extreme roll when it's right at the limit of its range. Otherwise it looks like it's working properly. Never owned a gimbal setup before - is some noise normal or are these supposed to be totally quiet?
