hinges (stab area)

First picture:
The horizontal stab.
I'm also going to use one servo and guide wires to control the rudders.
The stab is symmetrical but there is a bottom and top (bottom has servo hatches).
Again, I'll be using the hatches with the small rectangular holes.

Second picture:
Vertical fins and rudders.
Also left 1/8" covering for where the stab goes into the side of the vertical fins.
The vertical fins are multiple layers of balsa (rudders are built up).
All pinned hinges for all tail surfaces.

Third picture:
A better view of those triangular slots for the hinge pins.
