<HTML><BODY STYLE="font:10pt verdana; border:none;"><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> <DIV>Jim Ivey</DIV> <DIV> </DIV> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt Arial">----- Original Message -----</DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt Arial; COLOR: black"><B>From:</B> patterndude@attbi.com</DIV> <DIV style="FONT: 10pt Arial"><B>Sent:</B> Monday, June 09, 2003 12:57 PM</DIV> <DIV style="FONT: 10pt Arial"><B>To:</B> discussion@nsrca.org</DIV> <DIV style="FONT: 10pt Arial"><B>Subject:</B> Re: Sustaining Knife edge?</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 Park wrote:<BR>> <BR>> > I have a question to ask.<BR>> > Flying condition was very good.
