Started out tonight with the tail feathers. I decided to go with the v-tail not just for the marginal wieght and drag reduction, but also for the cool factor. Since I'm going to be using a bigger prop than this plane was designed for, I have extended each of the v-tail sides one inch to increase vertical area. I have also increased the angle from 110 degrees to 113, to get a little more vertical force from the elevators and less of a horizontal vector. I shaved a quarter inch off the bottom of the rear of each piece, as to increase the sweep back slightly, and I also swept the tips.
