it's going to be replacing my Real Flight 3.5 sim. One thing I like is you'll never have to pay for new aircraft and flying fields, you'll be able to simply download them.
Did you like the free AddOns? and have you seen the free download aircraft and flying fields at KnifeEdge.com?
There are over 4,000 free downloads at KnifeEdge for RF3.5, a thousand or so for RF4, and over a thousand for RF4.5.
It's hard to believe how much is available free for the better sims.
