This discussion is really beyond me, but from a practical point of view, I would set up the ailervator mix on a switch so you can turn it off and fly the plane normally in case it doesn't work right. I've known more than one person who experimented with things like this without a way to turn it off and the result was nearly disaster.

By the way, I was thinking about a flying V-tail for my design, Great Gonzo, but I have no idea how to create the pivots. Anyone have a link that I can look at?
