Side Note on Real Flight. I inherited an old 300mhz PC. Real Flight does fine on it. Also I have a version of that Ulitmate on my server with a lower pitch prop. As you get good with the G2 plane just keep making it smaller and smaller (in the edit part of the plane you can alter the wing span). They say it doesn't affect the way the plane flies but it really does.
