Will, thanks for the great explanation of PCAM's sim. As I said, I flew it as a P-51 and had a great time. It was set up for low-level flying through virtual "bridges", I think near Las Vegas. It was much more difficult than I expected. I loved it and did get better with multiple tries. I did think the stick forces were not realistic (although I haven't flown a real P-51), providing not much feedback at all.
