would also suggest looking at just aileron roll to inverted checking for correct
differential. If correct it will still be on same track before rolling. Best to
see visually if done going straight away.</FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT size=2>Well I have run into a trim problem with a plane that I have
not seen before. Time to tap into the wealth of knowledge on the
list.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The plane generally is flying pretty nice.
Uplines/Downlines are good, minor mixing for knifeedge stuff, good feel while
inverted...etc.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Problem rears its ugly head in rolling to knifeedge.
When using small aileron movement to slowly roll into a 4/8 or 4 pt for
example the plane will pitch to canopy. Not drastically but I would say
moderately, more than enough to cause a concern. However, if you do a
full 4 pt or slow roll with rudder coming in the pitch to canopy does not
happen. With good top rudder the plane is trimmed to fly very nice
straight knifeedge flight right or left.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I got to playing with is some today and when I would roll
from upright to knife edge with no other input other than the aileron
deflection the plane would have a predictable drop of the nose and would begin
going to the canopy.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>What am I overlooking here. Any ideas or has anyone
run into this before?</FONT></DIV>
