❏ 2. Repeat the previous step to make the leading and
trailing edge portions of the other stab skin. Glue the
sheets you just cut to the front and back of the stab
skins. Reminder: Aliphatic resin is recommended over
CA because it will allow time to position the sheets and
will be easier to sand after it dries.
❏ 3. While the glue on the stab skins is drying, make
up the ribs for the stab assembly by gluing a die-cut
1/8"[3.2mm] plywood rib doubler “S2C” to both
sides of four die-cut 3/32"[2.4mm] balsa stab ribs
S2. Glue one die-cut 1/8"[3.2mm] plywood rib
doubler “S2B” to one side of another stab rib S2
(make two of these, and be sure to make a right and
a left). Lastly, make two sets of root stab ribs by
gluing together two die-cut 1/8"[3.2mm] plywood
stab ribs S1. Note: If you forget which of the
doublers “B” are, they are the ones with the larger
hole for the brass tubing.

❏ 4. After the glue on the stab skins has dried remove
the masking tape and sand both sides flat and even.
Cut the Stab Center Cutout Template from the plan
and use it to mark the cutout in the stab skins with a
ballpoint pen. Cut and remove the section of sheeting,
but do not cut directly on the line—leave some
additional material to allow for positioning.
❏ 5. Cut out the corrugations and true the edges
with your sanding tool. Cut the corrugation fillers
from more 1/16"x 1/4"x 30"[1.6 x 6 x 760mm] balsa
sticks and glue them to the insides of the stab skins
the same as you did for the fin and rudder skins.
❏ 6. Cut the stabilizer control rod to a length of
6"[150mm] from a 4-40 x 12"[300mm] pushrod by
cutting off the threaded end. Discard the threaded
end (or keep it for your spare parts bin). Cut the
dowel spar to a length of 15-3/4"[400mm] from the
5/16"x 16"[8 x 405mm] hardwood dowel. Use a piece
of a paper towel or a tissue dampened with
denatured alcohol to clean any residual oil from the
control rod. Clean the inside and outside of the
11/32"x 6"[8.7 x 150mm] brass tube and the 3/8"x 1-
1/2"[9.5 x 38mm] brass tube as well.
❏ 7. Drill 3/32"[2.4mm] holes between the ends of
the die-cut slots in the plywood S1 Ribs to make slots
that will accommodate the stabilizer control rod. Also
drill 3/32"[2.4mm] holes through the punchmarks
through the ribs at the punchmarks in the B doublers.
