not fly in knife edge, but when you apply top rudder, the tail drops and if
there is dihedral, the top of the upper wing and the bottom of the lower wing
are exposed to the airstream which will roll the airplane back toward level
flight or if it is correct, will hold the wing vertical.</SPAN></DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN lang=EN-GB
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Now the question. Can make it fly
pretty good with a DA50, but there’s this enormous roll-coupling anytime you
touch rudder. Also some pulling to the gear, but nothing unusual.. Best way to
test it is to fly knife edge, it rolls on it’s back in both directions, very
quickly! The wing has NO dihedral. CG is definitely OK, falls nicely
straight down on stall turns</SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN lang=EN-GB
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Thought first it had to do with
dihedral, but in knife edge, the wing doesn’t fly? What could it have do with
it? Tried on simulator AFPD, roll-effect by lack of dihedral is
minor.</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN lang=EN-GB
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">So, I thought it’s the shape of
the rudder, I have to increase the bottom portion. So I did to a very
significant amount, lowering the center (balance of the surface if you cut it
out in cardboard) of the rudder-surface about 1 “, I noticed some real
improvement, but still far from OK. I had hoped that this much would have
reversed the rolling direction. </SPAN></FONT></P>

Mixing my radio, 20% rudder to roll, still way
insufficient.</SPAN></FONT></P>
