Hi Paul,
The easiest way would be if you are able to reach the receiver (assuming that it is installed in your aircraft) and just switch out the servo leads.
If this is not possible, I am sorry, this radio does not have the stick assignability of the 9Z.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
Lead Futaba Customer Service and Programming Technician
