<DIV>Ihncheol,</DIV>
<DIV>Fly the plane looking at the bottom of plane in knife edge in the
same circumstances as you did looking at the top. If you have the same
symptoms down wind, then your plane is probably ok, I think your
problem is the fact that airspeed + wind speed is considerably different
upwind than it is airspeed - wind speed downwind. In other words the rudder
has help holding the plane in knife edge, upwind. You also may be a little
nose heavy, which will aggravate the problem.</DIV>

<DIV> </DIV>How much right thrust are you compensating for when
flying L to R (seeing top <BR>of plane)?<BR> I think P-factor should
pull the plane to the belly (L to R) or canopy (R to <BR>L), so that is
not the answer. <BR><BR>--Lance<BR>> <BR>> <BR>> Ihncheol
