<P style="margin-left: 0.5in;"><FONT color="navy" face="Arial" size="2"><SPAN style="font-size: 10pt; font-family: Arial; color: navy;">Some servo electronics
could be temp sensitive. Measure the elevator on a cold morning then warm it up
slowly with a heat gun (carefully) and see if anything moves.</SPAN></FONT></P>

<P style="margin-left: 1in;"><FONT face="Arial" size="2"><SPAN 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>
