Have a look at ClearView. http://rcflightsim.com/?gclid=CK_P28...FRA_YAodGWpiFQ
There's a free demo and very detailed description of it.

I just got it. I'm very impressed with what you get for $40, It's performance is very close to the high priced Sims. It's only available for on line download. Of course this doesn't include a controller, but you can pick up an Esky on Ebay for under $20.

And no, I don't work for; nor am I afiliaited with ClearView in any way.

Have fun
