I've had No darn luck with those wee sullivan snake/cables.. ever. They always added so much drag that the servo was struggling or the control was just plain sloppy, usually both happened.
Sounds like something else might not have been moving smoothly causing excessive pressure on the wire, too stiff CA hinges possibly?
I've tried CA hinges but don't like them, they are either too stiff or simply fall out, I just can't get them right. In the wing shown above I've used the covering as the hinge and there is barely any resistance at all, a single 6g servo in the center is enough.
