Torque Drive Pocket Reinforcement Check
Check the Rudder and Stabilator torque drive pockets.
One early kit had a Stab drive pocket improperly installed..
Because you cannot see inside these structures, this very simple procedure will assure that
the factory workers did not overlook another one.
Rudder
Use a 1/16” carbide cutter to start two holes
about mid-span on the black injection
molded pocket flange (
see arrows
). For the
rudder pocket, use a #43 (.089) drill bit to
enlarge holes and make them about 3/8”
deep. Hold rudder skin in hand to assure the
drill does not get too close to the outer skin.
If the drill meets resistance of glue, the
pocket liner is properly secured.
If not, make (4) similar holes in both sides of
the flange.
Use a plastic syringe to inject Aeropoxy into
the holes. The glue can be seen merging
between the drilled holes.
Remove the excess glue and allow to cure
overnight.

Stabilators
Do the same procedure for the stab torque drive pockets except drill .8” deep into the stab.
The drill should engage balsa and/or glue. At the .8” depth there is a 1/8” plywood rib.
If there is a need for more glue, use the syringe to inject.
