I downloaded the AF7 through the Apple Store and on the left of the menu-bar there is an item "In-App Purcheses"
Through that menu item I was able to provide the serial number from the back of my Game Commander controller from AF5 and get the discount to upgrade to the AeroflyRC7 ULTIMATE.
In the AeroflyRC7 ULTIMATE, my Futaba controller works great through RX2SIM controller, just like the other software I use (NeXt, HeliX and AccuRC).
Thank you for your help.
