<DIV><FONT face=Arial size=2>I side with Keith. Your idea results in the
elasticity/deadband of the linkage being inside the feedback loop and those
effects were not accounted for when the designers chose stability
parameters. Results--- I'll bet the servos oscillate like
mad.</FONT></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I have been dealing with
elevator trim changes on my D.E.P.S. installation which has been worse with
cold mornings and warm afternoons. Last night on the way home from the field
I got the idea of figuring out a way to take the pot out of the servo and
mounting it on the control surface, that way the surface will always go to
it's set position regardless of how much the fuse has expanded or
contracted. Anybody ever try this, I know it could be done but is it
practical? My worry is vibration, sealing the pot from the elements, oil,
keeping a clean signal with the long leads to the rear and a positive
connection from pot to surface. Is this a dumb Idea? </SPAN></FONT></P>
