Top Flite TOPA0155 - Manual (Page 47)

❏
17. After the epoxy from the previous step has
hardened, sand the guide tube and excess epoxy
flush with the fuse sheeting. Sand the sub stringer
even with the fuse sheeting.
❏
18. Trim the front of the fuse skins even with the
fuselage top and former F6A. Trim the back of the
fuse skins even with the lower stab saddles and the
end of the fuse.
❏
19. Glue the second F6A former and formers F5A,
F5C, F3A and F2A into position on the fuse top.
❏
20. Make the stringers that extend from former F6A
to F2A from leftover 1/4" x 1/4" [6.4 x 6.4mm] balsa
sticks and leftover 1/8" x 1/4" [3.2 x 6.4mm] balsa sticks.
Glue the stringers into position. Note that former F3A
has no notch for the bottom 1/8" x 1/4" [3.2 x 6.4mm]
stringer, so the stringer butts-up to it.
❏
21. The same as the wing skins, make the last
skin for sheeting the front of the fuse by gluing
together two 3/32" x 3" x 36" [2.4 x 76 x 914mm]
balsa sheets to make a 3/32" x 6" x 36" [2.4 x 152 x
914mm] balsa sheet.
❏
22. Sheet the left side of the fuse between
formers F6A and F5A using a portion of the balsa
sheet prepared in the previous step.
❏
23. Sheet the same section on the right side of
the fuse the same way.
❏
24. Use the remainder of the 3/32" x 6" x 36" [2.4
x 152 x 914mm] balsa sheet to sheet the left side,
then the right side of the remaining portion of the
fuse from former F5C forward.
❏
25. Use masking tape to protect the sheeting,
then sand the aft edge of the sheeting over former
F5C. (We made a handy sanding tool from a piece of
1/8" [3.2mm] plywood and applied Great Planes
120-grit adhesive back sandpaper to it.)
