Last night I moved my CG back from 3.5" to 4.5" 1/2" at a time then flying it... this is definately what it needed It'll hold inverted with no stick now, knife-edge at 1/4 throttle then I can roll on a little power and more rudder and do knife-edge cuban 8's easy. It was windy so I couldnt try much hovering but the little I did up higher seemed much more stable and I was able to hold it into a crosswind hovering leaned over 45 degrees on knife into the wind and it stayed without rocking or falling out, does good pop-ups without dropping a wing and great knife-edge spins. I'll post more when I fly it in the calm!!
