RE: A good simulator?
I have that sim, and used it to learn lots of good stuff. When I got to the field and tried those things (ordinary flying, inverted flight, 4-point rolls, rolling circles....) everything worked just about like on the sim.
Make sure he's got the key code, when you install you have to enter the code. Mine's on a sticker on the jewel case, and I wrote it in Sharpie on the plastic, just in case it fades.
Best wishes,
