<HTML><FONT FACE=arial,helvetica><FONT  SIZE=2>There are at least two sets of 320/360 flyers, to wit --
<BR>
<BR>1. Those that routed the rudder cables per the manual, loaded with friction; <BR>and
<BR>
<BR>2. &nbsp;Those that routed them as straight as possible, hence relatively friction <BR>free.
<BR>
<BR>The high friction environments are self trimming at cruise once the ball is <BR>centered.
<BR>
<BR>The low friction installations will see variations at climb and descent and <BR>at different level flight speeds, sometimes because the canted engine <BR>installation changes the forces on the airplane. &nbsp;Differences will also occur <BR>if you have the big tail, long engine mount or whether fast build or not. &nbsp;<BR>Some of us will watch the auto pilot fly with &nbsp;wing low (usually left), until <BR>the rudder is trimmed.
<BR>
<BR>There are many ways to skin the cat. &nbsp;Mine was to use a mac servo and springs <BR>to internally change the forces on the rudder. &nbsp;I look forward to using the <BR>electric trim tab on the perfectly molded and factory pre-built Legacy.
