Evo 50 Blade Flutter

[Helio Addict]

My Evo 50 has been getting this bad blade flutter. It usually happens at high headspeeds and inverted maneuvers. This happened to me some time ago and it was a pitch servo that was bad, now It's happening again and from what I can tell the servo is fine. Any Idea's? I am using the maximum settings on the control head for the most responsive control.

Hard landing and the spindle is bent?

The head block on the evos tends to flare out and let the head rock, I would bet if you have had a blade hit this is your problem. I have seen bent spindles happen in flight on these too, and that can result in the head block flaring out. It happens by the jesus bolt, where the two slots are.
