Pots are not that durable either, they tend to wear around the center and you lose centering precision.. I even know some pattern flyers that will setup the servo with neutral off-center just to prolong servo life.. of course it used to be worse in the 70's, you had to replace the pots every few flights.. at least now they tend to last a flying season.
Anyways, that must be the reason they are still using pots instead of optical encoders. Thanks for the great review.
