STAGE 7: EPENNAGE INSTALLATION AND CABLING
Empennage assembly:
Center the horizontal stabilizer on the fuse-
lage top by positioning the spar at Frame
“I.” It is recommended that you strengthen
the joint by drilling through the spar and
longerons, into the vertical frame members,
to insert two small brads as you glue this in
place. (See Plan 04.5 and Fig.27)
Glue the vertical stabilizer pins into the
holes in the horizontal stabilizer. Finish this
up by rigging the bracing wires from metal-
gray thread (Fig.27). Use a turnbuckle on
each side in the rear where the thread passes
through the top of the horizontal stabilizer
and the bottom of the vertical stabilizer.
The forward of the two bracing wires has
turnbuckles where the thread passes
through the top of the compression bar on
the horizontal stabilizer and where it is tied
off at the nearest CAF05 on either side of
the bottom of the fuselage.
Control cabling:
Prepare by cutting the flanges from four
small brass eyelets (GS2-3) and filing the
ends smooth.
Stand the aircraft on its nose, using a block
of wood to clear the attached machine
guns. Brace the rudder bar and rudder into
their neutral position. Refer to figures 28-
30. To use the least amount of thread, run
the end through the tie-off ring on the rud-
der, then the right hand rudder horn,
through the fuselage and the far right fair-
lead on CAF13 (“e” on Fig.29), and
through a prepared small eyelet. Continue
the run through the right hand hole on the
rudder bar, back through the eyelet,
through fairlead “f ” on CAF13, and back
through the fuselage to the right hand horn
on the tail skid. Tie it off, then pull it snug
to the rudder bar, slide the eyelet against
the rudder bar and glue it and the thread.
Snug up the run back to the rudder horn
and tie-off ring, glue into place and trim.
Repeat for the left side. When the rudder
and rudder bar are released, they should
move normally.
Brace the stick and the horizontal stabilizer
to their neutral position. Cut off about 2.5’
of metal-gray thread, and tie one end to the
top right hand pulley on the control stick
(Fig.28). Run the thread forward, around
the right hand rudder bar pulley, going
from inside to outside, under the lower
stick pulley, and through the outermost
fairlead “a.” Continue the run back through the fuselage, emerging above the upper
longeron between Frames “G” and “H,” to
the upper right side elevator horn, through
the tie-off ring then the lower elevator
horn, and back into the fuselage between
Frames “G” and “H.” After passing this
through “b” on Fig.28 run the end
through a prepared small brass eyelet and
back to create a loop which goes over the
upper right stick pulley where you started.
Make everything snug and glue in place.
Repeat for the left side. When the stick
and elevator are release, moving the stick
forward should pull the elevator down-
ward; back, upward.
