The CG as per instructions was far to far forward for me...same problem on my Hydeout.
I've got it set 1.5cm behaind the wing tube and the wings set a zero.
Hands off inverted... straight, 45 degrees etc.
I aways set zero on the wings and correct down lines with CG. Don't understand the the principle of changing wing incidence. Surely, this is going to effect the set up between upright and inverted?

I prefer the zero setup and a neutral CG.
Mine you, a neutral setting it takes abit of getting used to.
