Top Flite TOPA0120 - Manual (Page 29)

allow proper aileron travel (refer to the cross-
section at rib W-10 on the wing plan for the correct
shape).
❑ ❑ 9. Tape the aileron to the wing and blend
the aft portion of the wing tip and the aileron to
create a smooth transition.
BUILD THE FUSELAGE
❑ 1. Test fit the shaped 1/8” balsa Main
Fuselage Side to the die-cut 1/8” balsa Lower
Fuselage Side. For a straight fuselage it is
important to have the fuselage sides straight and
both sides the same. Reassemble the parts and
check them against the fuselage side view on the
fuselage plan for proper alignment. Use CA and
CA+ to glue the parts together. Use a quick wipe
with a paper towel to remove any excess glue, as
this will make sanding easier. Keep in mind that
you are making a left and a right fuselage side.
❑ 2. Inspect the two fuselage sides. Choose the
Right and Left sides so the best surfaces will face
outward. Mark the inside of the appropriate part RI
and LI (for Right Inside and Left Inside.)
IMPORTANT NOTICE: Compare the two
die-cut 1/8” Plywood Fuse Doublers.
Label the shorter one “R” (right) and
the longer one “L” (left). This will set
the right thrust in the firewall.
❑ 3. Glue the Fuselage Doublers to the
fuselage sides. Use the wing saddle curve and the
forward tab (see arrows) for proper positioning.
Tape the Fuselage Bottom View over
your flat building board (we recommend
cutting that part of your plan loose to
make it easier to handle). Cover the
bottom view with waxed paper.
Important Note: You are building the
fuselage upside-down over the Bottom
View. This aircraft has right thrust built
in. Since the fuse is built upside-down,
this will appear as left thrust until it is
flipped over. Just follow the instruction
sequence and everything will be fine.
❑ 4. Pin the die-cut 1/8” plywood Forward
Crutch over its location on the plans. Make sure
the front edge of the crutch matches the plans for
the correct thrust angle.
NOTE: Some formers are not
symmetrical and must be glued in with
the proper orientation. Glue in all the
formers with the identification numbers
toward the FRONT of the model and
they will all be correct.
❑ 5. Drill 3/16” holes through the punch marks in
formers F-3, F-4, F-5, F-6, F-7, and F-8. These
holes are for the pushrod routing and anchoring.
You may confirm these locations using the cross-
sections on the fuselage plans.
❑ 6. Glue the 1/8” plywood Former F-3 to the
forward crutch at its location on the plans. It
should be perpendicular to the crutch with its
number facing forward.
