[NSRCA-discussion] Trim changes

[Brian Billings]

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?
