This should easy to do..

I am wanting to set a switch on my Devo12 to do rolls on my tri-copter..most likely the trainer switch but i can't remember how to do it...Could somebody give me a little help to remember how to do this? I thought i had it but not quite..

Thanks all..

EDIT: I remembered it just took a little while for my old head to remember...went a head and also set up all DR on one switch as well making it easier ...
