❑ 4. The stab and fin Leading Edges (LE’s) are
cut to length from the 1/4” x 30” tapered
balsa stock. Cut two pieces about 1/4”
longer than the length shown on the plans
for the stab LE.
HINT: Bevel the front edge of the stab
and fin ribs to match the sweep angle of
the LE stock. This will give you a better
fit and a stronger glue joint.
❑ ❑ 5. Starting with the right half of the stab,
pin ribs S-2 and S-5 to the building board over their
locations on the plans.
❑ ❑ 6. Center the LE vertically on the front
edge of ribs S-2 and S-5. Glue it in place with CA.
❑ ❑ 7. Center the TE vertically on the back
edge of ribs S-2 and S-5. Glue it in place with CA.
❑ ❑ 8. Glue ribs S-3 and S-4 in their places.
All of the jig tabs should rest on the work surface.
❑ ❑ 9. Glue rib S-6 to the LE. Glue the die-cut
3/32” balsa TE at Balance Tab between ribs S-5
and S-6 at the location shown on the plans.
❑ ❑ 10. Trim the LE and TE near the stab
center so they match the endpoints shown on the
plans.
❑ 11. Repeat steps 5 through 10 to build the left
half of the stab. The left half of the stab is built
beside the right half and the two halves do not
touch for now.
❑ 12. Trim the 3/8” x 9/16” x 4-1/2" hard balsa
stab TE Joiner, if necessary, to fit between the
S-2’s. Securely glue it to the stab TE’s and the
S-2’s using CA.
❑ 13. Check the fit of the die-cut 1/8” plywood
Stab Joiner (SJ) and adjust if required for a good
