simply dial enough EXPO in to get manageable sensitivities arounsd neutral with

<DIV><SPAN class=444070918-10022005><FONT face=Arial color=#0000ff size=2>That
usually means like the plane feels like it has a break-point in the stick

<DIV><SPAN class=117045117-10022005><FONT face=Arial size=2>Ok...I have a
question for the Aeronautical engineers in the group... All of
this discussion has been centered around an assumed desire to get a linear
relationship between our stick movement, and that of the control
surface. Clearly the effect of moving a control surface on the aircraft
is proportional to the amount of movement...but is it linear?? I have to
beleive it's not... Just don't know the mechanics behind
it...</FONT></SPAN></DIV>
<DIV><SPAN class=117045117-10022005><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=117045117-10022005><FONT face=Arial size=2>Assuming it's
not...(And I'm betting for some portion of the throw is close enough to be
considered linear and then at higher deflections it becomes either more or
less efficient) is there really a purpose to trying to exact the linear nature
of the stick/control surface linkage...or it is an exercise in retentiveness
:)</FONT></SPAN></DIV>

<DIV><SPAN class=117045117-10022005><FONT face=Arial size=2>I also know that
our spring tension on the sticks in not linear...especially around center...so
it seems unlikely that what "Feels" linear isn't anyway.</FONT></SPAN></DIV>

<DIV><SPAN class=117045117-10022005><FONT face=Arial size=2>To me it's akin to
comparing two high end stereo systems both of which have specifications well
beyond the range of human hearing....</FONT></SPAN></DIV>
