3. Note the location of the arm portion of the
joiner wire. This determines the true location of
the 1/8" x 1/8" balsa
rib —not necessarily where it
is shown on the plan. (You can see in the photo
how the rib on our model needed to be moved
inward a bit).
Cut the rib from a 1/8" x 1/8" x 24"
balsa stick and pin it to the plan so it is contacting
the arm of the joiner wire.
❏ ❏
4. Remove the stab mount/joiner wire assembly
from the plan and finish building the stab using
the remainder of the 1/8" x 1/4" x 24" balsa stick
and an 1/8" x 1/8" x 24" balsa stick.
❏ ❏
5. Remove the assembly from the plan and
carefully sand both sides flat, smooth and even.
Be careful not to weaken the structure by sanding
it too thin. Round the tips, LE and TE.

6. Cut a stab spar from the 1/16" x 1/4" x
36" balsa stick, then glue it to one side of the stab
where shown on the plan. Turn the stab half over
and cut an 1/8" notch in the 1/8" x 1/8"
root rib to
accommodate the elevator joiner wire.
❏ ❏
7. Glue an additional 1/16" x 1/4" balsa stab
spar to the other side of the stab the same as the
first. Use the remainder of your 1/8" x 1/8" x 24"
balsa stick to make the rib caps that fit on the
front and back of the stab spars on the top and
bottom of the stab. Blend the rib caps and the tip
of both stab spars to the stab by sanding.
❏
8. Return to step 2 and build the other stab half
the same way. When you position the edge of the
stab mount/joiner wire 1/16" from the end of the
stab, you’ll have to turn it around so you get the
correct spacing for the other side of the joiner.
