Vibrations on a T2D gimble

[mikim]

Hi,

I have installed and configured my T2D gimble and am fairly happy with the results.
The camera seems level and moves well.

I can still feel very slight vibration to the touch though when the quad is stationary on the bench.
My question is; how much vibration is normal, should this feel dead still or will there always be a little "buzz" so to speak?

I am worried that when I start filming in very bright conditions I will start to see shutter vs vibration artifacts.

cheers
