While you are at it, download the free G Pilots Guide. It helps to have a good joystick and throttle, but I think you can get by with mouse only. You can set the thing to run on dual monitors, pfd on the left one and mfd on the right one, and it works well. I do not think there are any free and legal versions out there.
I have one and it is well worth the money. I recently began flying the CSP G and struggled some. Is there a free Garmin G Trainer floating around out there available for download? I have heard good things about the G in Flight Sim but that is not an option at the moment. Registration is fast, simple and absolutely free.
