Feiyu Tech new Mini 3D Pro Gimbal - Don't Buy!

I have just purchased a new Gimbal and wanted to install on a new Phantom2 since its going to be dual remotes set up.
Initial start up and testing the Gimbal discover this issue
which as sees on VDO makes vibration all over.
Nothing connected just power supply directly to Gimbal.

I am not sure but I think this all shorten upper damper plate design
is not a good idea as the torque from the pan arm become very sensitive

If you look for professional so this is probably not the one:
