I have both parts of the article, and they are great.
I have already determined the my plane is to tail heavy.

I balanced at 4.75" (manual states 4.25" to 5") I flew
someone Else's Edge balanced at 4.25" and I liked that better.

On my plane if you roll inverted on a 45 degree up-line the
plane will hold or even climb a little. At level flight if you
roll inverted it will fly level hands off.
