Hi Xirtic88,
My first plane was Hangar 9's P51 Mustang PTS which was a great gift of my loving wife, Unfortunately that plane crashed as Rx failed. I was flying it without air brakes and flaps were neutral as I wanted to fly it fast. I would buy this plane again as this is really a good plane. I found twitching in the left aileron servo as connecter wire was little loose, it was a major glitch and did give me hard time during flying. As far as training on that plane is concerned, yes it's a good trainer, but without a senior instructor that plane will crash in NanoSeconds so please don't do that. Simulator is not that good ofcourse but for a newbie it gives a fair idea of gimbals, how to fly it land it and take off. Atleast something is better than nothing. FMS is also a good free simulator available on the net as the purpose is to learn and enter into the hobby as you have already been flying Cub so I think you'd probably learn very quick on that. Its a beautiful flying baby, once ofcourse you are expert in it, it is also a 2nd fast plane. Go for it and wish you all the best
