Horizontal stabilizers are joined with a composite tube and antirotation pins.

Make sure you tie any servo extensions
so they don’t come apart in flight.
Because the composite material can be
abrasive with the vibrations of flight,
shield or wrap all of the exposed wiring.
The horizontal stabilizers are
supported and held in place with a
composite tube that must be drilled
and tapped. Start by epoxying a
hardwood dowel into each end of
the stabilizer tube. Center the tube
and drill a hole through the bottom
stabilizer skin into the hardwood
block that is built into each horizontal
stabilizer. Continue drilling through the
tube, but not through the upper surface
of the stabilizer itself.
Insert the tube through the fuselage
and insert the other stabilizer, making
sure that both stabilizers are tightly
seated against the fuselage. Drill a
matching hole in the other horizontal
stabilizer. Tap each hole in the
stabilizers with a 4mm tap to complete
the assembly. Set the wings, ailerons,
horizontal stabilizer, and elevators aside.
