Looks sweet, I have combat flight simulator 2 which is pretty fun. This looks much better than that though. Can you fire the 30mm chain gun on those A-10's? I love watching that thing tear through tanks armor like a hot knife through butter.
you can buy it on amazon or ebay for a pretty good price. the learning curve is steep, so be prepared to crash A LOT before being able to do basic maneuvers. but it can be very fun, and its the most realistic modern flight sim ive ever played
