So the size issue argument is: “If you turn it sideways, it is basically the same size as the blackhawk.” Ok, fine it can land in about the same footprint. Thing is that the blackhawk can fold the rotors in so you can fit it in a confined space or for transport easier. If they can’t fold the wings in…
They did simplify the tilt mechanism, instead of rotating the engine, they just bend the prop shaft. So time will tell how failure prone that is.
