Enrique - that's a truly excellent analogy !

BTW, I found the realflight sim that I have (the older RFD version) is fine for things like basic fixed wing / heli practice, but totally unrealistic for jets. Supposedly if you spend a lot of time tweaking the settings you should be able to get it more realistic, but the defaults are not.

I should soon be receiving my Aerofly sim next week, and look forward to comparing it ot the old RFD.
