Ask yourself, how many standard servos do you see failing on any given weekend?? Gears or motors??
Very good point! I would estimate that approximately 8 out of 10 guys who fly at our field have older servos and a few have the digital servos. Nothing there is really the high end mega metal gear ball bearing stuff. The fact is in the past year I have only seen ONE servo that I can recall have an issue and it was a very old servo and that was when it was extremely cold at the time and the control surface was stiff and put extra pressure on the servo. The guy went home and cleaned it up, lubed the joints and plane is fine now.
I bought some planes from a fellow that were built in the early nineties and the servos are still working fine. I only replaced one because it was chattering a bit!

I do like the digital servos but not planning on replacing them all at once. I will just do that over time.
