I am using a GY611 and have developed a terrible jerky waggy tail. I have changed the servo from one of my other heli's so that can't be it. Could it be a bad bearing or some kind of interferance? It doesn't jerk or act funny when the engine isn't running. The only thing I've changed on the heli is the clutch shoe. Any idea's???
