Here's what I did. I bought RealFlight standard with the controller that plugs into the serial port. Later, they came out with an upgrade to RealFlight Deluxe. Bought that too. Later, they come out with RealFlight G-2 upgrade. Bought that one too, plus now I have all the Add-On disks ( Volume 1~4 ). Worth it? You bet! I do wish I could get the new USB interface so I can use my Futaba 9ZAP, but.....

Now, if they come out with a G-3 upgrade, I'll have to wait and see how much it is.... and what it offers before I'll buy it.

Best regards,
Mike
