You guys tell me if I should send it back. There is a intermediate buzzing noise that comes from the upper gimbal. When I received it yesterday the gimbal lock was off inside the box. Im kinda nervous about how long it will last, though it only buzzes if the cam is 0 degrees. You can put your finger on the top case of the gimbal and you can feel it shake a little when it buzzes. Everything moves fine and doesn't bind. Haven't even flown yet because I want to resolve this issue. You guys got any ideas?
