<DIV><FONT face=Arial size=2>OK thats helpful Ken. I have a pattern ARF
that I am tinkering with and having some fun. The downlines are really
nice, but I hold too much down on inverted flight. I'll move the CG aft a
little and see where that takes me.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Here is my follow-up question because I can't help
myself. Lets assume you have a plane with wing and stab at 0
degrees. Lets assume further that you have no elevator trim and the
engine has no thrust adjustments. If this assumption airplane actually
flew level...would an aft CG be responsible for creating the right AOA on the
wing to create lift? Am I understanding this correctly?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for your input!</FONT></DIV>

<DIV><FONT face=Arial size=2>If you had a little positive incidence in the
main wing, to fly level in upright flight, you would have it corrected by
incidence in the stab or possibly elevator trim. When you roll inverted
the correction remains constant.</FONT></DIV>

<DIV><FONT face=Arial size=2>Bear with me on this question
guys...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I know the test for CG is to roll inverted and
watch for nose down or tail down. But relative to everything else why
wouldn't wing incidence screw you up inverted? Seems to me that all
things remaining equal, if you had a little positive wing incidence and
level flight upright that the nose would drop when inverted....Where is the
blind spot in my logic?</FONT></DIV>
