So I have a Futaba Skysport 4YF 4-channels and a Futaba Conquest 6-channel. I want to make the Skysport the slave. How would I set it up? I bought the cord but it doesn't specify which one is going to be the master. Does the slave require a battery and crystal, or does the master provide that and the trainer switch just switches to stick controls that come from the slave? Also could I make the dual rates on the master work when the slave is on?

Thanks!!
