Default JR ST-47 lifespan

I have three JR st47 purchased about the same time. However, all 3 now have severe jitters about center, and do not reach end points, they just jutter back and forth all around the range, slowly making it from one end point to the next.

Two went bad a first and just tonight in front of my eyes the other gave, would of been a bad day. Gears are fine, I even replaced them. It seems the Pots go bad perhaps? I confirmed with other RX and radio, it is in fact the servo.
The servos were never bound, they were just either on the aileron, and the other a retract servo.

Anyone else have this issue with st-47? I think I got them perhaps 2-3 years ago?
