I just picked up a Lanier Dominator 500, question I have is about the advantage or dis-advantage of the V-Tail. My first thought was to just build with the standard Tail configuration but then got to thinking there might be some plus to the V-Tail design.
Otherwise why bother, right? Good point.
A V-tail has the same total area as the equivalent conventional tail setup designed to the same margin of stability. The theoretical and hopefully realized advantage comes in that there are only two fuselage-stab junctions generating interference drag and two tips and their inherent tip losses, versus three.
I bet if you search v-tail on the Q500 forum there have been oodles of discussions on the subject. There was one here maybe two weeks ago as well.
