RE: HIGH SPEED STALL
any aircraft of any size will stall at any speed if it has enough "up" or down elevator. elavator on a real airplane is set so it will be full up at the point where the aircraft slows down to the point that the wing looses lift. if propely designed it will be in the 3 point landing attitude. it will have full up,,,stall and have all 3 wheels touch the runway at the same time.
