Refer to this photo while gluing in the turtle deck
stringers.
❏
3. Test fit, cut, then glue seven 1/8" x 3/8" x 24" balsa
turtle deck stringers into the notches in formers F6-B and
F7-A. The three bottom stringers on both sides of the fuse
extend all the way to the TE of the fin.
❏
4. Bevel the inside edges of the stringers to get a good fit
to the fin, then glue them to the fin.
❏
5. Glue leftover 1/8" x 3/8" stringers to both sides of the
fin in line with the top, middle stringer. Sand all the stringers
even with the fuse sides above the stab. Blend the aft end of
the stringers to the fin TE.
❏
6. Cut a 1/4" x 1/4" x 24" stick to fit on both sides of the
top, middle stringer between formers F7-A and F6-B, then
glue it into position. Round the stringers to match the shape
of the turtle deck.
❏
7. Sand the front of the stringers even with former F-6B.
Glue together both halves of the die-cut 3/32" balsa former
F6-A. Glue F6-A into position.
Refer to this photo for the following three steps.
❏
8. Glue the die-cut 1/8" balsa formers F1-A, F2-A, F5-A
and F5-B into position where shown on the plan. Use a
builder's square to be certain the formers are vertical when
gluing them into position.
❏
9. From two 1/8" x 3/8" x 30" balsa sticks, cut the three
stringers that run from F1-A to F4-A. Glue the stringers into
position.
❏
10. Glue a sheet of leftover 3/32" balsa to the aft side of
former F4-A and shape it to match the former.
Make the Main Wing Struts
❏
1. Use a hobby knife and a straightedge to accurately cut
the front main strut template from the fuselage plan.
❏
2. Lightly spray the back of the template with 3M 75
Repositionable spray adhesive or 3M 77 Super spray
adhesive. Stick the template to a 3/16" x 3/4" x 6" plywood
stick. Spray the other side of the ply stick with spray adhesive
and stick it to another 3/16" x 3/4" x 6" plywood stick.
❏
3. Use a razor saw to cut the notch in one end of the front
main struts, and use a bar sander with 80-grit sandpaper to
sand the bevel on the other end of the front main struts.
