Working on a design right now, the full size original had just a bit of dihedral to the horizontal stabilizer. I can build this dead flat but would love to build in some dihedral. I could see using two servos for the elevators but this is a pretty small build, and besides in general terms that's an overkill solution to something that looks like it should be simpler. I could see running two pushrods tied together from one control arm, and there are those really lightweight flexible pushrods, I believe they call those specific ones Snakes. I guess there's no mechanically correct way to tie the two sides to each other, right? They hinge on different axes. What's the most elegant solution?
