iron to reseal the glue. Set the iron to it’s highest
setting and then press the sheeting back into the rib
with the iron. When you remove the iron, continue to
press the sheeting to the rib with a cloth. The
sheeting should now be firmly adhered to the rib.
BUILD THE STABILIZER
❏ ❏ 1. Use leftover 3/32" balsa to make six
1"squares. Use leftover 1/16" balsa to make six
1/2" squares. These will be used as shims.
❏ ❏ 2. Cover the stabilizer plan with wax paper.
❏ ❏ 3. Use CA to glue the die-cut 1/8" balsa
trailing edge and tip together.
❏ ❏ 4. Cut the 3/16" balsa leading edge to
length. Glue the 1/8" triangular die-cut brace to the
leading edge with CA, centering it top to bottom.
❏ ❏ 5. Slide the 3/32" shims under the wax
paper at the trailing edge of each of the four ribs.
Let it protrude from under the trailing edge 1/8" or
so to support the ribs. Do the same to the leading
edge using the 1/16" shims.
❏ ❏ 6. Pin the leading and trailing edges in place
over the plan, supported by the shims. Glue the
leading edge to the tip with CA.
SPAR
2"
1/8"
❏ ❏ 7. Trim the main spar to length from 3/16"
hardwood. Taper the last 2" at the outboard end, to
1/8" as shown..
NOTE: In the following steps you will be cutting and
gluing ribs for the stab from 1/16" x 1/4" balsa
sticks. Select material for the opposing top and
bottom ribs that have about the same bending
strength so the section will turn out symmetrical.
❏ ❏ 8. Trim the four bottom ribs to length from
1/16" x 1/4" balsa, keeping in mind that they will
bow around the main spar. Carry the inboard rib all
the way to the leading edge so it will glue to the
triangular brace. Pin the spar down over the ribs so
that the ribs are snug to the building board. Glue the
ribs to the spar, leading edge and trailing edge
using CA.
❏ ❏ 9. Trim short pieces of 1/16" x 1/4" balsa
and glue them to the forward end of the ribs against
the leading edge. These will support the top ribs.
❏ ❏ 10. Trim the top ribs to length and glue them
in place with CA.
❏ ❏ 11. Trim and glue the 3/16" sq. root pieces.
Tapering of these pieces can be left until later.
❏ ❏ 12. Remove the stab from the building board
and add the 3/16" filler shown in section S-S. Leave
about 1/16" of the filler sticking out from the
inboard side of the inner rib to form a shelf for the
inboard sheeting.
