I don't think I got much out of FMS. I found it really easy to fly anything with it. A good sim like G3 would probably be quite a different story, but that's expensive - like $175 to $200. For $105 (including shipping), I bought an Esky Lama2 and that really helped me with orientation. Being slow and so easy to hover, it was easy to concentrate on other things. I guess whatever works is good.
