I haven't forgotten this thread, just been a little busy this week.

Today I show the elevators being built. I realized I needed to do this before making the servo mounts for elevator and rudder, but also that I needed to coordinate them some.

The elevator is built in two sides. This is just a style thing, and to get useful surface action for a landing flare with the increased outer area.

The frame is 3/8" sq, same as the stab. The single "rib" near the middle will hold the control horn (I'm using the hardware set from the E-Flite Habu 32). It aligns with the servo arm - you'll see that setup later on.

After the frame was dry, I attached it to one side of the sheeting (pre-cut to shape). These will be beveled to give a taper. Attaching the one side of sheeting now makes them stronger and easier to hold while beveling.

I prefer the built-up control surfaces because they are lighter, stronger, and resist warping.
