<DIV><FONT face=Arial size=2>Thanks Nat. This is the kind of topic that I like
to see. I enjoyed watching your voodoo fly the last time I was in Baton Rouge,
but that was a couple of years ago. I still remember flying one of your old
designs a few years ago, the Pussycat. I put a lot of time on that plane flying
the old novice schedule. Have a great day, Terry</FONT></DIV>

<DIV><FONT face=Arial size=2>The wing must be at zero incidence in the KE to
perform correctly. Since the stab is trimmed to ' raise ' the nose
something has to balance the stab force. This is where the shape and/or
the attitude of the fuselage comes in, to produce that force <U>when
yawed</U>. The fuselage does have a steering
effect.

<DIV><FONT face=Arial size=2>So, the wing is actually .5 pos to the stab.
Very similar to most pattern models. What is the engine thrust? Do you have
the vertical fin at the cg like your ealier voodoos? Would you say that your
fuse shape has a "stearing" effect in knife edge that would require the wing
to be set at a negative measured to the centerline of the fuse? Interesting.
I have heard of some models needing negative incidence to fly right, whereas
some need positive. Great topic. Terry</FONT></DIV>

<DIV><FONT face=Arial size=2>Terry,</FONT></DIV>
<DIV><FONT face=Arial size=2>I can see where my post was confusing. The
fuselage is symmetrical. The wing and thrustline are at 0.4 deg
neg to the fuse C/L and the stab is 0.9 deg neg to the
C/L.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It is not readily apparent that it is flying
tail low. The "incidence" of the fuse produces the pitch to gear moment,
when yawed, needed to balance the lift "down" force of the stab in
KE.</FONT></DIV>

<DIV><FONT face=Arial size=2>Wouldn't that mean that the wing is still
positive? How does the fuse look flying by? Does it fly tail low, or is
it level? At this point, what is the thrust set at? If it is set at zero
in relation to the fuse centerline, wouldnt that mean it has positive
thrust in relation to the wing and stab? Wouldnt you get the same effect
by setting the stab at zero, and the wing at .1 positive, and the
thrust at.........? What effect does your fuse shape have on the
aerodynamics that creates these settings? Interesting topic, lets
hear more. Thanks, Terry</FONT></DIV>
