[C320-list] Help for older Autopilots

[Tony Murphy]

Jeff,

I too recall a different answer...
http://lists.catalina320.com/pipermail/c320-list-catalina320.com/2012-March/
037778.html

And the geometry of the linear arm and pulley assembly on the rudder post
would seem to dictate that a linear drive cannot drive a wheel assembly as
far as a cable system which is only limited by the length of cable around
the pulley.  I¹m doing a terrible job of describing this... But I think you
are concerned about the exact problem I¹m trying to describe.
