on the down elevator only and it won't feel like you are holding lots
of elevator when inverted.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I do this on all my models. I run the CG very far
forward compared to most people. The model tracks better. It also snaps better
too.</FONT></DIV>

<DIV><FONT face=Arial size=2>Looking at my Pinnacle log books..... I have 2 degs
more travel on the down elevator side and I also have 10% less

<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>
