Top Flite TOPA0140 - Manual (Page 34)

❏
10. See the following sketch and trim the sides
of the cockpit floor to match the contour of the
instrument panel, former 5 and former 6.
❏
11. Cut the 1/4" x 5/16" x 15" [6.4 x 7.9 x
381mm] forward cockpit rails and the 1/2 “ x 5/8"
x 6" [12.7 x 15.9 x 152mm] aft cockpit rails to the
length shown on the plan and glue them to the
cockpit floor and formers. The aft cockpit rails are
inset 1/4" [6.4mm] inside the forward cockpit rails.
❏
12. Trim the rails to match the contour of the
formers the same way you did the cockpit floor.
❏
13. From two 3/16" x 3/16" x 36" [4.8 x 4.8 x
914mm] balsa sticks, cut the stringers that fit in the
notches of the formers immediately above the
main stringers on both sides of the fuselage and
glue them in place. These stringers extend from F2
to F10. Cut the remaining four stringers that fit
between formers 5 through 10 from four 3/16" x
3/16" x 24" [4.8 x 4.8 x 610mm] balsa sticks.
❏
14. Use the leftover balsa sticks from step 13 to
make the three forward stringers and glue them
in place.
❏
15. Use a ballpoint pen to mark the center of
the middle stringer on the front of former 1A. This
is a reference mark that will be used later to align
the stab.
❏
16. Glue the 1/8" x 3/16" x 24" [3.2 x 4.8 x
610mm] fuse sub stringers into the groove of both
main stringers. The easiest way to do this is first to
insert one of the stringers into the groove and make
sure it is fully seated. Then, apply thin CA from the
outside. Position and glue the other fuse sub
stringers the same way. You can glue the bottom
after you take the fuse off your building board.
