........A better design would rigidly mount the stab to a small linear bearing running on a precision-ground chromed rod. It would weight a little bit more, but it would constrain the stab against hammering in turbulent airflow. It's probably not a difficult retrofit for someone with some fabrication and welding skills (not me, in other words!).
Dang it Eric!! I was digging my credit card out to put in my order from you!!!
