I have been flying for about a year now, mostly warbirds. I have had a chance to spend a some time with both Realflight 2 and Aerofly Pro simulator. They are both way better than FMS. However, I Just received Reflex XTR. I don't feel that I'm experienced enough to know how really accurate the physics are in each of the simulators. But I will tell you this, Reflex XTR is the only sim I have ever tried that left me feeling like I had been really flying at the field. I feel like I'm getting quality stick time when I use it. [8D]
