Just another item to mention about R/C simulators, they are a big aide in keeping you sharp on the sticks when weather conditions don't allow flying at your regular site. For us in the north-east, sims help get us ready for spring after a long cold winter.

Also, there are a lot of decent sims out there. Real Flight is good but don't fall into the trap of flying with a cockpit or chase view because that isn't going to help you one iota when flying R/C unless you have your plane equipped with FPV technology. Remember, controls are setup to act as if you are in the plane. But when you are on the ground watching your plane come back at you (assuming the plane is in the normal upright attitude), the throttle and elevator work the same but the rudder and ailerons work in reverse to your perspective. Learn to fly from the ground view only and leave the game stuff (air combat, etc.) to those who want to pretend they're Bud Anderson or Pappy Boyington.
