ORIGINAL: flyX
It feels just like any other sim to me. Set it up accordingly.
It would be interesting if you can ever get any of your models to fly and feel like mine.
Maybe that would help, but all the planes that come with the simulator feel like they are being flown on a planet with less gravity than earth, they float.
I did try a GWS Formosa that one user said flies like the real thing and, well, no, it didn't. I have used Realflight and, having flown 2 of the planes modeled in the sim in real life, found that sim to be much more accurate.
Of course, one is free and the other is not. But I learned on a simulator not sold anymore nor supported by XP (RC Simulator by Ripmax, anyone?) that has spoiled me for a better sim.
I find FMS, boring. And, as it doesn't fly like anything I fly, I don't get any value from playing with it.
