I've been using RealFlight G2 for about a month now. I really like it! I originally purchased it to learn to fly my trainer plane but since there was also helis on the sim I thought I'd give them a try. At first it was a bit difficult to get the helis to hover but I'm getting the hang of it and it really didn't take very long. I haven't even flown my plane and I'm ready to buy a heli....well almost, it's just this money thing in the way
Anyway, the G2 gives you an mock controller so you get the feel for a real radio; you can also plug in your own radio if you have one. Some of the other features are the ability to control wind speed and direction and simulate misc. failures. I think they did a good job on this sim.
