Thanks guys this is all excellent info. How tight do you normally tighten the wires?
Tight enough to eliminate slop, but not so tight as to damage the servo. Equaly as important is that both halves be tightened to the same tension. A good way to check this is to pluck them like a guitar string. They should sound the same ''note''. A higher note is a tighter cable.
A neat and simple technique you could use to simulate flight load is to wrap a couple rubber bands around the horns and secure them behind the model. Then pull and lock the plane placing the bands in tension. Measure the elevator halves travel as you move the sticks, observing if there's any difference. If you go to Ron Ellis' site, Grotto2, you should find the technique referenced there.
Ron's technique also involves a servo driver which drives to specific millivolt output, and that would complete the loop of a fairly sophisticated arrangement, but it may not be necessary for your application
