RE: 12FG Channel Order
Be aware that if you keep the pre-existing channel configuration in the 12FGA (and I assume the other FASST transmitters also) then if you use a previous transmitter (say a 9CAP, etc.) as a buddy box the student transmitter will be all out of whack.
I had to re-assign my channels in the classical way in my 12FGA to be able to use the 9CAP as a student radio.
I have suggested to Futaba (Hobbico) to introduce an entry in the 12FGA programming to correlate the master and slave transmitter channels... but... no action yet.
The above also applies to the 12FGA even if you are using a 72 MHz module.
