Walexan- if you had elevator flutter you should suspect everything on the airframe. I had aileron flutter that smashed the belly pan construction, and loosened the canopy. What I didn't know is that it also broke loose most of the Robart point hinges in the ailerons and elevators. ( I had covered the wings and stabs with a single sheet of covering to include over the hinges to the trailing edges.) The elevator fluttered on the next flight after repairs as they basically were unhinged under the Ultracote. The covering held the plane together again.

I ended up having to cut out small squares under each hinge and using a syringe to inject Monkey glue into the hinges. I also had a lot of stab repair to do at the fuselage. After that, it flew fine. Monkey glue was too thick for the syringes I had, but I patiently forced it in. One plastic syringe barrel exploded under the pressure and sent glue all over the shop with a bang.
