Top Flite TOPA0155 - Manual (Page 23)

Sheet the bottom of the center section
❏
1. Cut a hole through the top sheeting where
shown on the plan for the servo wires and retract
gear air lines.
Refer to this photo for the following two steps.
❏
2. If building flaps, cut the hatch supports from the
1/8" x 1/2" x 30" [3.2 x 12.7 x 762mm] basswood stick,
then glue them into position where shown. Sand the
hatch supports even with the bottom of the ribs.
❏
3. Cut the flap hinge blocks that go in the wing from
the 3/8" x 3/8" x 30" [9.5 x 9.5 x 762mm] balsa stick.
Glue the flap hinge blocks into position where shown on
the plan. Be certain the hinge blocks align with the
bottom of the ribs as shown in the cross-section.
❏
4. Cut both wing bolt blocks to fit between ribs
W1 and W2 from the 3/4" x 1" x 6" [19.1 x 25.4 x
152mm] balsa stick. Glue the wing bolt blocks to the
center TE spar and the ribs.
❏
5. Sand the wing bolt blocks even with the bottom
of the ribs. Only between the W2 ribs, bevel the
trailing edge of the top TE sheet to the same angle
as the ribs. Hint: Use a piece of leftover plywood as
a “fence” to keep from sanding past the #2 ribs.
❏
6. Lay the wing upside-down on your flat
workbench resting on the top sheeting and the
center TE spar. Sheet the bottom of the wing with the
3/32" x 12" x 24" [2.4 x 305 x 610mm] balsa sheet
prepared earlier. If building the wing with fixed gear,
first cut slots in the sheeting to accommodate the
landing gear rails as shown in the photo. The same
as when sheeting the top of the wing, it is
recommended that aliphatic resin be used, except
for gluing the sheeting to the LE spar where medium
CA is best. Do not glue the sheeting to the servo
hatch supports. This will facilitate trimming the
sheeting when fitting the hatches later.
❏
7. Sheet the bottom of the wing over the wing bolt
blocks between the W2 ribs and the center TE spar
using a portion of the 3/32" x 6" x 24" [2.4 x 152 x
610mm] balsa sheet prepared earlier. Save the
remainder of this sheet for the inner flaps (or inner
flap sheeting if not building flaps). After sheeting the
wing, do not trim the bottom of the center TE spar
until instructed to do so (after the outer panels are
joined to the center section).
❏
8. Use a long bar sander with 80-grit sandpaper
to sand the top and bottom sheeting even with both
ends of the center section and the center LE spar.
Glue the 1/4" x 1" x 24" [6.4 x 25.4 x 610mm] balsa
leading edge to the sheeting and LE spar. Trim the
LE even with the sheeting and both ends of the
center section, but do not final-shape until instructed
to do so.
The Sea Fury was designed and built by Hawker
Aircraft Ltd., Sutton Lane, Langley, Bucks, England.
❏
F3. Drill 1/16" [1.6mm] holes through the
landing gear rails for the #2 x 1/2" [12.7mm]
screws for the nylon landing gear straps.
Temporarily secure the gear to the rails with the
screws and straps.
Note: Mount the molded ABS wheel covers to the
landing gear wires as shown on page xxxx for the
retractable landing gear wires.
