If your radio lets you mix from the trainer channels then you can make up a simple switch board and then just plug it in.
I thought about using Labview as the software to control these systems, which are then fed to a transmitter. Labview would dedicate certain "go-codes" to certain channels and would control it that way. I don't know how involved that will be since my EE colleague will be the one designing the system in Labview.
That being said, i will check out your suggestion. Theres always more than 1 way to do something, perhaps your suggestion will be less complicated.
