Paper,
I don't think the amplitude or ips of the vibration involved in model turbines, what little there is, would have an effect on our airframes. Not to mention the extremely low "exposure" time our airframes are subjected to this tiny high freq vibration. FS aircraft spend a lot more time flying under far greater stresses (environmental, aerodynamic...) than we'll ever see.

Nonetheless a post flight inspection is always a good idea no matter what aircraft type you fly. Even a simple wipe down inside and out can pay big dividends.
