My guess is that it's that bit of rubber that's protecting the axle...I

the mount is "bouncing" a bit. The effect is not really visible with the
old
camera when it was mounted atop the tail, where there isn't any rubber
involved.

Gonna try to protect the axle with nylon or wood, instead.

My guess is that it is not the rubber, but instead, the axle flexing.

Try mounting the camera on the axle over far to one side, right next to the
axle support, and see if you still get the "bounce." Use the rubber and
everything else just the same, for a control.
