The servos with strong low lash metal gears like the 7115 offer much stiffer control surface holding than do most of the plastic geared servos. When thee Avionik B10s went with the 7115s the stiffer holding of the aileron got rid of all flutter at high speed.
Gears break from flutter and from overloading--sometimes just accidents on the ground
If you make the plastic gears large enough to not break the servo gets too big for fitting in thin wings.
