Since I am NEW - I will ask a few questions and tell what I did.
The spoiler vibrations are just strange - so I am looking for a solution.
I did something that helped allot. The bottom fin is very loose - so I took Waxed Dental floss and created a washer by wedging it between the metal washer and the bar. It helped about 50%+
I will continue to try to get rid of it..................
Any other ideas?
