Tail parts are done the same way. I'm using 3/8 balsa for the rudder and vertical stab. The fuse top will also be 3/8.

I used 1/2 inch triangle stock for the top of the fuse, and 3/8 for the bottom. This will require me to design fuselage frames and the firewall to fit. I'll probably widen the nose slightly because it's a tight fit for the engine mount.
