Real Flight has demos for G3.5 and G4


Here is [link=http://www.realflight.com/free-g4-demo.html]G4[/link]



Unless you have a usb controller or adapter for your tx, it doesn't do you a whole lot of good to try the demo. But it is free, so you might as well download it and open it up. It will give you some idea of what you're getting with G4.
