I don't think it really depends on the age of the camera whether or not one has to adjust the RF. If the RF gets knocked out of alignment it needs adjustment. That can happen within the first week of using a camera or after twenty years.
But it's good to know that this is an easy fix. I'm soon selling mine and so far the RF's still spot on but I'll make sure to pass on the info about the adjustment to the next owner.
