Buzzing/Humming Sound from H33D on GoPro Video

[ThePhantom]

First of all, I can live with the humming/buzzing sound recorded only on video to my Gopro when the H33D cable is attached (audio is garbage on any quad anyway and will be replaced by a diff track in post). However, does anyone actually have an H33D that does not exhibit this weird buzzing/humming sound with the H33D ribbon connected? (no tape mods or anything, just straight out of the box). I'm curious.

Same buzz, same config, same curiosity.

I have to specify, this is only present on the H3 and not the H4.

I think it is a balance issue as the gimbal motors are trying to stabilize the camera.. Mine was reverse - weird vibrational buzz with certain positions of the GoPr4 camera attached that was not there with the GP3 at all. I recalibrated, updated the Zenmuse firmware on my Quickrelease setup and still had the buzzing but much less so. Then I added a dime with some adhesive on the lower hinge of the gimbal opposite the GoPRo4 and the buzzing completely went away.
