<DIV>If it has even a little dihedral, turn the wing up side down. If it's like
most sticks, the wing foil should be symmetricall. The thing's already ugly so,
why not?</DIV>

here's a good one. The owner of the L.H.S. asked me what I thought
about<BR>this and I couldn't come up with a good answer. He has a Hangar 9
Ugly<BR>Stik - the real big one. I can't remember exactly what it's called.
Guess it<BR>has a gas motor in it. It's big. He says he has it trimmed so it
will fly<BR>inverted with just a very slight bit of down elevator (almost
none). Ok, so<BR>it's not nose heavy, maybe even a little tail heavy. Now,
when he flies it<BR>knife edge (either side) it pulls severely to the canopy.
I mean like it<BR>will fly a complete circle. It needs almost 3/4 down
elevator to fly<BR>straight. It's beyond a mix - fix. He also says that it has
a bit of roll<BR>couple when flying level (not knife edge) but it doesn't
pitch severely up<BR>or down under these conditions. Any thoughts? I guess you
can rule out C.G.<BR>because if anything it should pull to the belly
considering how it's trimmed<BR>to fly level upright and inverted. I haven't
flown it so I can't add too<BR>much more. He builds OK so I don't think
there's anything way out of<BR>alignment, but again I haven't seen it yet so
maybe there is. What should I<BR>look for if I get my hands on it to try and
help him?<BR><BR>John Pavlick<BR>http://www.idseng.com</FONT></BLOCKQUOTE></DIV>
