Min Throttle shuttering

Brand new build. It's a 155 frame with MN1804 motors, 12A Kiss ESCs, and nanowii fc.
I have not had a problem like this before on my bigger frames. The entire frame starts vibrating incredibly fast when it's flying or if I pick it up like in the video. If I set it flat then it behaves normally. You can just listen and hear it. At first I thought it was a prop balance issue, but it's happening without props on as well.
My Min Throttle was at 1150. If I turn the minThrottle up to 1200 it appears to go away. Any thoughts?

Min throttle (0 min 21 sec)


Any help is appreciated,
Jacob

Yea all the motors. If I watch it on the computer the values bounce up and down like crazy.
I thought it might be he PID too but didn't know if it could be that without props on? Lowering P to 2 stopped it but so did raising the min throttle while keeping P at 4.
