RE: Horizontal tail (beginner question)
The picture I posted is the result of a contest between me and some Aero-engineers.
We all started with a fiberglass tube, and then cut identical wing and Stab cores. I elected to use a fiberglass rod in the main wing for the spar. Black "low-heat" covering over the main foam wing. The Stab cores were balsa sheeted and two aluminum tubes glued into the foam. Steel rods go through the fuselage andthe front steel rod goes into each of thtwo inverted "L's". The back steel rod is screwed into the associated side. Since each L is independant of the other, the associated Stab side can move independantly. This means that the Stabs can move with each aileron... ie on the left side, the aileron goes down, that side stab leading edge moves up.... Right side does just the opposite.(real life F-14 TomCats did this) A mechanical mixer is used up front to mix aileron/elevator. Further mixing in the receiver produces the Flap/elevator mix. Winding up with axial mix and elevator/aileron/flap output.
As for the contest, first flight demo, everybody else quit....
heheheh
