Pauly,
I totally agree. Moving the CG is absolutly the best way to go.

I was just pointing out that some trainers have way more incidence than is actually needed for stable upright flight. Just reflexing the ailerons usually has minimal effect on the upright flight charastics (we are talking SMALL changes here), but can really show up inverted, so on SOME airplanes, SOMETIMES adjusting the incidence helps overall. On ALL airplanes, getting the CG set "right" helps a lot. I gotta be more clear . Certainly, messing up the upright flight handling to make it fly better inverted is just stupid . If you change the wing incidence, and the plane flys poorly, change it back .

Btw, when you do move the CG back, it's not a bad idea to lower the elevator rate a hair. You're going to find the plane is much more responsive in pitch upright or inverted with a more rearwards CG, so it's normal to reduce throws a bit as the CG goes back. And just because the elevator become more sensitive doesn't mean the CG is too far back.

When I trim out a new combat plane, I am going to for the absolute tightest turning radius I can get, both upright and inverted. I move the CG around, adjust the elevator travel, and change the aileron reflex, all a little at a time to get the best balance. Sometimes less elevator + a more rearwards CG gives a tighter turn, somtimes moving the CG forward and increasing the elevator works better. They are all very closely related. Fortunatly, with most planes, you aren't trying to push to the absolute edge of the flight envelope.
