There is no way to transfer models from the 12Z to the 18SZ. The 18SZ will have to be programmed manually, though the numbers used in the 12Z will be very close.
Are you serious? What about to the 18MZ?
Nevermind. Rhetorical question. Sent the 18SZ back to Tower. If I have to reprogram all 15 of my airplanes, it might be time to look at JR.
