<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:

lang=EN-GB style='font-size:10.0pt;font-family:Arial'>. Many problems, first of
too heavy, wing profile weird but symmetric. High speed stalls at a blink.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;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 size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;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 size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;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>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Any ideas on what I could do? Mixing my radio, 20%
rudder to roll, still way insufficient.</span></font></p>
