2. Test fit a die-cut 1/32" [.8mm] plywood outer
flap frame (OFF) to the wing. If necessary, trim the
outer flap frame to fit well.
❏ ❏
3. Use the outer flap frame as a pattern
to make an outer flap skin from leftover 3/32"
[2.4mm] balsa.
Refer to this photo for the following two steps.
❏ ❏
4. Cut the outer flap LE from the remainder of
the 1/4" x 1/2" [6.4 x 12.7mm] balsa stick leftover
from the inner flap LE’s. Glue the LE to the inside of
the balsa flap skin. Glue the die-cut 1/16" [1.6mm]
balsa flap ribs F6, F7 & F8 to the flap skin and the
flap LE.
❏ ❏
5. Cut the outer flap hinge blocks from
leftover 3/8" x 3/8" [9.5 x 9.5mm] balsa and glue
them into position. Use a bar sander with 80-grit
sandpaper to sand the flap LE even with the tops of
the flap ribs and sand the TE of the flap skin to a
bevel that is also even with the flap ribs.
❏ ❏
6. Glue the outer flap frame to the top of the flap.
❏
7. Return to step 1 and build the left outer flap the
same way.
Hinge the flaps
Start with the right side.
❏ ❏
1. Use a straightedge and a ballpoint pen to
lightly draw reference lines (indicated by arrows in
the photo) across the bottom of the wing and flaps
over the hinge blocks. Be certain the lines are
perpendicular to the TE spars.
❏ ❏
2. Make a drill jig by drilling a 3/32" [2.4mm]
hole through a leftover basswood stick 1/8" [3.2mm]
from one edge. Glue another piece of leftover
basswood to the top of the block, extending 1/8"
[3.2mm] beyond the edge.
In addition to a catapult takeoff on aircraft
carriers, the Sea Fury also featured rocket-assist
takeoff with the installation of six electrically-fired
rocket motors. The motors were attached to a
frame mounted to the underside of the fuselage
aft of the main gear doors.
