My C of G is 145mm back from the LE of the wing at the root it seems to be ideal, this was how it all worked out, no church roof required or any movement of servo's or Rx it just worked out perfectly as assembled.

Using a 5S 5350Mah pack against my 6S 4350Mah pack will possibly be the same all up weight, if you are using TP batteries yours will be heavier. I put these with a 4S pack to use in my 2.1M Composite ARF Extra.

Contrary to popular belief a heavier plane will grove through the manouvres better than a light one, but what you do need is light wings to stop inertia from taking rolling manouvres to far, but as you say each plane is a subjective thing what works for one person is not necceseraly what another person wants, I can't fault my set up with the 6S and the AXI 4130/16 on a 16 x10 gives me 9 mins of hard flying, using DS821's all around. Just another opinion.
