I’m amazed when we see these type of posts about a dangerous design change or dangerous build, and many experts who weigh in, yet the poster’s slowness to absorb the warnings.
Or we're being trolled. I'm just sayin'....

In a word, yes. Based on what you've shown, and what you've described, grounding the plane until this is sorted out *is* the only prudent response.Are you seriously condemning this airplane without ever seeing it?
We've had a couple of threads recently where someone went much further down the rabbit hole than you have in terms of describing a situation that was clearly dangerous to most of the VAF crowd, but denying that there was any issue. After a while, the only explanation that made any sense was that the poster was trolling us and didn't even own an RV. So when your first post here is something as potentially dangerous as your situation, you might be able to understand some people might think it's less than genuine.trolling? Don’t people come to this forum with real problems seeking advice of the RV community? This is my first post on this forum. I turned to you when two local RV mechanics and the factory had no ideas. You have been great with ideas to check. What have I done to cause vitriol?
Hang in there folks. 1) working with someone at the factory. 2) scheduled renown RV expert to look at the tail 3) can’t get to airport because of road construction. Will get you photos as soon as I can 4) I am well aware that I own a Lemon. I can’t sell it in this condition. Are you seriously condemning this airplane without ever seeing it? A dozen A&Ps deemed it airworthy over the last twenty two years. They actually inspected it and signed the airframe logs. None of the other owners did anything. We are trying to correct problems as they occur. Rudder oscillation is the latest. 5) we haven’t flown it since you made your comments, so have patience. We will update you as soon as we learn something. 6) trolling? Don’t people come to this forum with real problems seeking advice of the RV community? This is my first post on this forum.

Scott has applied outstanding skills for thread-upset-recovery.
Applause . . .
Moving tail forward caused some slack in the rudder cables. A&P installed bushings that stretched rudder cables. Rudder oscillation disappeared.
Factory rep agrees that ill fitting tail inspection panel probably caused disturbed flow over rudder.

Vne is not necessarily the number on the airspeed indicator. On RVs, it's true airspeed. Flying out of Colorado, the indicated airspeed will be lower than true airspeed, and that needs to be taken into account.
Also, it's not likely that you had full-fledged rudder flutter because you survived. Flutter is usually destructive, almost explosively so. Can you describe what happened and what the flight conditions were more thoroughly? Did the post-flight inspection reveal any damage?
