I fully agree with what has been said before, simulators help; LOTS.

I would like to add that Aerofly Pro seems to be the best for physics. I only have maybe 2 hours total on RFG2 so im not the most experienced with it. But out of the box AFP is waayyy more realistic than RFG2, but again, I have limited time w/ it and maybe some minor adjustment parameters could help it along. FMS is the first place to start if you dont want to spend $130-200+ on a sim, lots of d/ls for FMS and AFP on the net which make them a little more reasonable.
