I sent my 14 in last year to get serviced, haven't used it since. Tried to transfer a jet program from 18 to 14 and it tries, then the light flashes red and freezes the tx. I've used this tx for buddy boxing before with the 18, just wondering if I missed an update? Not sure what else it would be?

Thanks

Because the 18MZ has more channels, the telemetry functions, and more model functions, models save in it cannot be transferred to a 14MZ. You can only transfer between other 18MZ transmitters.
