Though this might be considered a bit off track please bear with me here. I have a EI G23 powered Carl Goldberg Extra 300 built in 1995, which is still being operated on the five original Futaba S148 std servos, which were upgraded when new with a BB top cover.
The model has never suffered any crash damage and the servos all work perfectly. However due to their age and the fact that servos technology has improved quite a bit since then, I am wondering if I should replace them, even though the model has had maybe only 40 or so flights to date. Your thoughts please.

The old addage, "If it ain't broke - don't fix it", has a lot going for it as far as I'm concerned, Karol.
I ran the same servo set up as you have for many years in highly stressed airframes. Never a single failure.
