Hi Bax,
I think I got it figured out. I am using the 9C and I made a mix- master elevator slave flap and used flap as the vector. It works and is on a switch, when activated moves with elevator and when deactivated centers. I'd like to use expo with just the vector/flap. Is there any way with the 9C to assign expo to flap?

Thanks for your help
