Be sure the little springs on the trim tab are installed and good on your preflight inspections. They will hold the trim tab in full up in the event that the control cable breaks and prevent the elevator flutter, which you described, that can be dangerous. One person told me that when his control cable broke and the little springs were broke or gone, the only way he could stop the dramatic flutter caused by the trim tab flapping, was slow flight and the violent flutter and control wheel flutter stopped until he could find an airport and land. I replace mine with new ones a few years ago.
