<DIV><FONT face=Arial size=2>Sorry Guys, I have some thoughts and opinions on
this that are based upon my own logic, however flawed,and which may or may not
coincide with someone else's logic.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Anytime you have a control system that is based on
a system that incorporates an oscillatory motion (fore/aft up/dn) the ultimate
result of this motion will generate wear somewhere within the system and wear
translates to slop.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think my contention would be that Lance had it
right in the first place and was ill-advised by some well intentioned souls
who may have had what they assumed to be good results, but failed to base
their conclusions on really long-term experience(who really knows for
sure?)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have long felt that pull-pull cables
(vinyl-coated steel) present the most reliable connection for the elevator
and rudder inputs.They do not require that the horns be expensive
ball-bearing units, they are the lightest by far and due to the fact that they
are always under tension the generated wear manifests itself against only one
wear surface instead of the two in the push-pull set-up. If the installation can
be modified in such a way that the servo can be mounted just ahead of
the stab the COE of the fuse can be rendered virtually
inaffective. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>With time, you may experience some slight lessening
in cable tension (very slight) which can quickly be rectified by disconnecting
the clevis and spinning the eye a half turn at each connection.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I have used Kevlar thread and continue to do so,
but not on two-meter projects.Kevlar stretches for quite a period of time before
settling to it's final length.</FONT></DIV>

<DIV><FONT face=Arial size=2>This rots. I've used pull pull forever and
switched to the deps system due to heavy promotion by Mike Harrison and Bryan
Hebert. They say it will be more precise. Can anyone corroborate
this? I'd hate to switch to a system that has more downside than
upside.</FONT></DIV>
