Despite the high winds, I think one thing I came away from the latest testing was that the plane needs more lift to accomodate the extra weight. It can fly as is, but the stall speed is quite high. So I've added 3" to the wings, with a bit of a dihedral. It makes an incredible difference! I can toss it and it will just glide down (as opposed to 'crashing down'), and I can fly it slow enough that I can almost fly it around the office--though the turning radius is too large to turn around without turn stalling. Seems much more stable now. Unfortunately, it's STILL windy outside, so I can't get the full effect. It should be good though, it just keeps getting better with each revision.
