I can see how the frontal area would be less than a conventional tail, but I can't see how they would be lighter... still the same pushrods and control horns, and I would imagine that equal surface area means equal mass in materials and they would weigh the same. I guess the diffrences are exagerated with a built-up stab vs. a solid piece with holes. I should just stop contemplating this. It's trivial.

Does a properly designed V-tail give the same control authority as the conventional counterpart? Also, do v-tails exibit a sort of adverse roll with yaw inputs? (It kind of seems like they would work as ailerons in a way)
