Keeping up with the '3D printed components' it seemed logical to use them to secure the Depron fin and tail plane particularly as the tail has dihedral so built in two pieces.
It also meant the whole tail could be built as a complete structural unit which can be simply glued glued onto the fuselage skin.
As each control surface has its own servo there are only servo wires to be run forward inside the fuselage.
The elevators are top tape hinged but the rudder uses three 3D printed hinges.
The hinges are printed progressively smaller to match the reducing thickness of the fin & rudder assembly.
Once the fuselage skin is made good around the tail it carries all the loads directly into the fuselage.
The APU tail cone is also 3D printed.
Now comes the rather tedious and fiddly process of connecting it all up.
My eye sight is not quite what it used to be for soldering 32 AWG servo wire connections!
