Adjusting the recentering damping
Two standard dampers are included with the AVA base.
These dampers make it possible to adjust the damping
for the recentering.
You can remove the dampers for springier movement of
the flight stick grip, and direct Force Feedback.
To customize your AVA base to the maximum extent
possible, you can use zero, one or two dampers.
