I wasn't sure about realflight, but I recently decided that when finances allow, I want to try helis. Well, after some minor initial setup issues, I am very happy with it. Just from my experience so far, if you go with G2, spend some time setting up the viewport so that the flight looks realistic, but the plane doesn't go out of sight directly after takeoff. Those extra binocular viewports and such are handy for trying new thing, but I try to do without, since I don't have binoculovision in real life. Sorry if the preceding was worded confusingly.
