color=#0000ff>I assume the one post you refer to that did not deal with dihedral
was mine. I hope you were able to look at the pictures of my Express
(based on Nat Penton's Voodoo Express). If you were, you will have noticed
that the design of this plane is not conventional by any stretch. I do not
claim to be an expert in aerodynamics or aircraft design and I am still
struggling to comprehend the specific aspects of the design that contribute to
the unique flying characteritics. I was able to reap the benefits of years
of experimentation by Nat and I have an aiplane the flies with very minute
roll or pitch coupling with rudder application, and has no effects from spiral
slipstream. I have not flown it in calm conditions yet to be able to
evaluate the amount of roll or pitch coupling, but it I know it is almost
negligible with the amount of rudder required for straight and level knife-edge
flight...</FONT></SPAN></DIV>

<P>
<DIV> I ask this question the other day and got a few replies, all dealing
with dihedral, with one exception. Seems that there could be and is much
more to this. #1 Could the wing be moved up or down instead of dihedral? 2#
Couldn't the rudder size and position, sub fin added or
reduced? Sense the 2 piece wing offers less possiblities of changing
dihedral than the old one piece wing.</DIV>
<DIV> Designers?</DIV>
<DIV> Please reply to all and remove the sender.</DIV>
<DIV>Thanks </DIV>
