Its not comercial jet kinda crap as you say, in fact, it has R/C airplanes built into the game... and if you want an R/C simulator game,
Great Planes RealFlight G3.5 w/InterLink Plus Mode 2
And this game is essentially like FSX except for a few little goodies MS throws in, but you get the true to life realism with X-plane. And you can fly tons of things, including a space shuttle, you can go into space, or fly on mars, with loaded mars physics based on its atmosphere and other conditions.
EDIT- And i would HIGHLY suggest you start with an R/C trainer, those are difficult enough to start with, i know, i have one. R/C turbine powered jets are one of the more difficult things you could think of to try without ever doing something like that before. Now you didnt mention if you have ever flown one before, im just assuming by what you said that you havent.
