While most of the models work reasonably well, the Blade mCPX is very different from the real thing. The Heli-x version moves around a lot more than the real one, which has the stability of a 450 size heli.
Little Nellie still works as a helicopter and nothing like the autogyro that it should be. Is there anyone who can model it as an autogyro? I am not clever enough to do this on a computer, though I have built and flown model autogyros.
