When coupling my tailwheel tiller arm to either the rudder or to pull-pull cable, I use a spring arrangement much like the FS Cub. I bend .035 music wire into a "U" shape and then put small hooks at each end. using one of these inserted into each end of a compression spring (from a ballpoint pen if the size is right) I then hook the rudder tiller arm or the pull-pull cables to one end of the "spring" assembly on each side and the other ends to the tiller arm on the tailwheel. Sounds complicated, but is not hard to do and like the FS assembly is failsafe and cannot overstretch. Not inventing the wheel, just reducing the size to our needs.As a further aid, I use an on-board voltage monitor. Anytime a servo is at limit or something is binding, the voltage monitor will drop into the red zone indicating a voltage drop due to the stall or bind. I can then fix the issue before the first flight or before every flight.
