The disk wobbles after you add some (not much) collective, it has never been crashed. I only have about 4 flights on it now and it seems like it is head speed related. Funny thing is when I go from normal to idle up there is not any change in head speed with the stock settings on a Dx6i. I lowered the throttle curve in normal a bunch just to see if I could hear it change going into idle up and it does but not as much as I would think. The head speed seems lower than by buddies running a DX7.

I checked the main gear and nuts on the servo and all is good. Seems to be getting better with time.

I had a relatively light crash into grass from 6-10 inches that spun the main gear on the shaft and before I figured that out I had intermittent shakes as I was hovering. Once I fixed that it went away.

I would search the mCPX forum for additional vibration related threads and you'll likely find a lot of information. It would also be helpful to have a more detailed description of the symptoms you are seeing and when they occur.
