I didn't try the "push the tail down" CG method but as you can see in the picture at the beginning of the post, it was balanced right at 223...The K100G weighs 2lbs, 14oz. The K85G2 weighs 1lb, 13oz. Less weight there will allow me to use a lighter ECU battery. Hopefully save another 6oz. May even replace the UAT with a smaller one and save a few oz there too. As far as throws and expo goes, I was at the spec'd rate at takeoff and had 40 points of expo on the elevator at high rates, 25 at low. I do have crow mixed in with full flaps, about 5mmr worth. I have experienced a stall with my 2.2m Predator, getting a little slow coming over the top of a loop, this was something very different, seeming to fall out in the turns...but not particularly steep banked ones.
Everything sounds good to me...
