4-Stroke vibration? Not here. Flying mine with a TT .46! I tried 2 replacement aluminum plates before I switched to steel. I've found the mounting bolt to the beam comes loose. The engine mounts are always tight. Since I religiously check the plate mounting bolts and switched to steel, I've had zero problems. I sincerely think just keeping the mounting plates bolts tight should solve the problem.

John,
I was replying to Saltys problem, who is running a 4 stroke, who started this thread.
