RE: Pull out of hover = Unlimited Vertical?
My Ultimate was my first truly unlimited plane. I could do a 5 foot take off roll, pull straight up and do a hundred points of a four point hesitation roll, with as many snaps in between as you wanted. If you put the sticks into the corners and just held them there, I'd say you would get four or more snaps, and then it might try to fall. If you centered the sticks and put the nose back up, it would begin to accelerate back up again. I guess that's what you get with a 9 pound plane and a Webra 120 though...
I think that the criteria of pulling from a dead stop hover is fine. My personal feelings are that that is still marginal in the realm of unlimited ability. If the plane is struggeling for altitude, it doesn't seem unlimited to me. I like a little more authority before I say it is really unlimited.
