H3-3D and Hero 4 Black

Having read various posts that said that the H3-3D would work with the Hero 4 Black, I decided to risk it.
However, having updated the software etc it works, after a fashion but all 3 motors make a loud buzzing noise when working. I assume that this isn't normal or is it? Could this be due to the Hero 4?
Also I'm using the Aux 3 switch on my DX8 to operate the tilt. This also works after a fashion but I can't alter the max tilt angle in the assistant ; I can't move the slider. At the moment it points down at about 45 deg and won't go horizontal, but will point vertically down. The assistant readings are 1000 (pointing vertically down) and -44 at the 45 deg position. The Aux 3 travel goes to 100% in both directions.
Any suggestions on how to fix this?
Thanks in advance.
