I may push my luck a little and change to Nyrod before changing the servo. (not advising anyone else to do the same) This should tell me if it is vibration or RF noise. If I still have issues than I would assume the servo is bad from being vibrated. If this cures the problem then it's most likely it was RF noise.

If you keep it above the strip in a safe dead stick landing area that would be a great test.
PS you already know this, but test with lots of height.
