Odd vibration issue.. X and Y are not the same

Has anyone see this before… the X and Y vibration levels are different.

Any ideas on how I may trouble shoot this or what the problem may be?

Also, I am assuming the X direction is in the pitch, Y is in the roll, and Z is in the Yaw. Is this correct?

I tried to attach the log, but it says it’s too big?? It’s only 4.4 meg.

What kind of vibration dampening does it have? Attach a picture of dampening along with FC.
Maybe the vibration dampening has different stiffness in x and y.

Do you have any cables resting against the FC? or any pulled a little tight?

The Z axis is vertical vibrations not yaw. That’s why high Z vibrations can influence the altitude of the uav.
