<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff>Hi
Ihncheol..</FONT></STRONG></DIV>
<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff> A
couple of thoughts come to my mind. Not knowing what plane but is canopy on
perfectly straight?. Does vertical fin have a slight twist,? Speaking vertical
twist here.. are you using pushrods and does it flex back a little when
being pushed instead of pulled and that is direction of weak rudder.? Is
your output on servo wheel balanced with its deflection.? in otherwords are you
getting more torque in one deflection versus the other.? These are just
some of the issues I would be looking at and this doesn't include all but will
give you some starting info. Hope this helps...</FONT></STRONG></DIV>

<DIV><BR></DIV>I have a question to ask.<BR>Flying condition was very
good. Almost no wind on ground level, maybe a few<BR>MPH in the air
(flying height). Wind direction left to right.<BR>When I fly knife edge
from right to left facing the top of the plane, very<BR>little rudder is
required to stay on without going up or down.<BR><BR>However, from left to
right facing the top, the plane just can not stay and<BR>keep
dropping.<BR><BR>What could be the cause of this?<BR>Side
thrust?<BR><BR><BR>Thank you,<BR><BR>Ihncheol
