Hey CeeGee, You could set up a programable mix to do the twin elevator system. I did it with the futaba 7 cap, the only problem I had was if I adjusted the trim for the elevator, only the master would trim out and I would have to use the subtrim for the slave. Try this link [link]http://www.futabarc.com/faq/faq-9c-q512.html[/link]. It shows you how to set it for channel 2 and 7 but I think that you could use any open channel.
