"I dont think you will find too many gc pilots using fsx yet regularly, there are not any good payware planes available yet. I play around with fsx, but fs9 still takes the bulk of the flights"
FSX is installed and has one payware aircraft (SR-22) that I use to buzz Seattle tower from time to time. Off-line since SB4 is still in the works. And Justin and I have flown with shared cockpit a couple of times which is a lot of fun! But for "real" flying it is all FS9 for me!
