I have them both and fly Aerofly much more precise and correct for 3D flying, hovering, flat spins, aileron control while hovering and fully stalled to mention a couple of Aeroflys strong-points, but as many have said, for a pilot who doesnt 3D I find all the fields on G2 much more pleasant to look at... the fields on Aerofly feel small and crowded, there are none with a nice clear horizon that isnt cluttered with mountains or hills or ships or buildings. For just flying around G2 is awesome, G2 is good for even some 3D... but when it comes to all out 3D and nothing but... Aerofly takes it all the way. And yes, the Realflight controller does work fine with Aerofly, you just have to be sure to plug in your Aerofly serial interface because the program requires it be there for the program to work, even if you're not using it... plug it in and throw the cord behind the desk. Leave your G2 controller plugged into the USB port and go into settings on Aerofly and configure it as a joystick. And make sure your Realflight controller is configured in your windows control panel too and is a recognized controller. I also wish Aerofly had an online flying option like G2, that is so much fun and one reason for me to keep G2.
