I just got the Real Flight G 3.5 for Christmas and its pretty nice ...although i dont have any experience with other simulators

it comes with a transmitter that plugs into the usb port and adapters for use with other radios

only one problem so far .......the spring for the elevator control came loose ( it doesnt center any more ) but the hobby shop said that they would swap it out for me when they get some more in at the end of the week

Im having fun with it so far
