I think one of the best flight simulators is the Great Planes G3. It has realistic graphics and the models look real and fly like the real thing. It has a tons of planes and helicopters. It is not cheap at $200.00 but I think it is worth every cent you pay for it. It also will provide you with a TX or provide a usb cable to fit your own TX.
