Joe,
Your answer is in your statement of symptoms and its really quite simple. Everything you have right now results in a pull to the canopy when you're trimmed for straight and level which just happens to be up trim. So you need to do something that will create the need for down trim compared to where you're at right now.

If you increase the wing incidence, it'll climb at the trim settings you currently have and you'll need down trim which should fix all or most of your problems. The other way to get there is to move the CG back which will also make the plane climb compared to where you're currently at and you'll need down trim which should fix all or most of your problems.

The choice for me would depend on how the plane feels when you fly inverted and how it snaps. For now, just stick with the inverted feel. You should need a little down elevator stick to fly inverted. If you don't, you're tail heavy and I'd go with the wing incidence increase.

If you need a lot of stick to fly inverted, you're nose heavy and I'd try moving the CG back a little before changing the wing incidence. You may need a combination of both, but only do one or the other at a time. The key here is to get rid of the up trim you're flying with. That should solve everything.


BTW, if you change the incidence, don't be afraid to crank on the adjusters. For most setups, 1 full turn results in a relatively small change. Just write down everything you do so you can put it back if necessary. I put heavy black Sharpie lines on my ball driver so I can tell when I've turned it exactly one turn.

That plane flies great with 1/2 degree down thrust, at least, the 3 I built did.
