With one motor on the right side, I added counter weight on the left (tin coins).

__Update3__: I added a shorter version of gimbal_arm1. This makes it possible to run the system without counter-weights - as a consequence the total weight is reduced, but I had to move the lens out of the center.
This and the use of harder dampening balls makes the
