BUILD THE WING
Make the wing skins
❏
1. The same as the balsa sheets for the tail
surfaces were made, make five 6" x 24" [152 x
610mm] sheets, and four 9" x 24" [229 x 610mm]
sheets from 22 3/32" x 3" x 24" [2.4 x 76 x 610mm]
balsa sheets.
❏
2. After all the glue has dried, make two 12" x 24"
[305 x 610mm] sheets from four 6" x 24" [152 x
610mm] sheets (there will still be one 6" x 24" [152 x
610mm] sheet remaining).
Prepare the landing gear ribs
Retract options:
If building the Sea Fury with Robart #605 HD retracts
with 3/16" [4.8mm] wire struts, there are two options.
The “long-strut” option represents the correct scale
length of the landing gear struts. However, because of
poor ground handling over rough grass fields caused by
the unusually long length of the struts, the long-strut
option is recommended only if flying from smooth,
paved surfaces. If flying from grass fields, the “short-
strut” option is recommended due to improved ground
handling. If installing any one of the Century Jet Models
retract options recommended, due to their design and
rigidity, the struts may be left at the scale length no
matter what surface you are flying from. Note: Most of
the instructions depict the installation of the Robart
gear, but apply to both the installation of Robart gear
and the CJM scale gear. Where necessary, separate
instructions and photos are provided for the installation
of the CJM scale gear.
❏
1. Place the center section of the wing plan.
Follow the instructions to prepare the landing gear
ribs for the right side of the center section first.
Perform this step only if installing #32425 CJM
Top Flite Sea Fury system with scale struts.

R2. Use a hobby knife to cut out one set of die-
cut 1/8" [3.2mm] plywood rib doublers W4A-F and
W5A-F along the embossed lines as shown in the
sketch. Do not cut out the areas indicated by the
dashed lines, as these are for the fixed landing gear rail.
❏ ❏
4. Use 30-minute epoxy to glue the rib doublers
to a die-cut 3/32" [2.4mm] balsa wing rib W4 and W5
as shown on the plan and in the photo. Note: If
installing Robart #605 retracts, glue die-cut 1/8"
[3.2mm] plywood rib doublers W4A-R and W5A-R
to the ribs. If this is your first time through, be certain
to make the ribs for the right side of the center
section by gluing the doublers to the correct side of
the ribs (the ribs shown in the photo are for the
right side).
❏ ❏
F3. Use a hobby knife to cut out one set of die-
cut 1/8" [3.2mm] plywood rib doublers W4A-F and
W5A-F along the embossed lines as shown in the
sketch. Do not cut out the areas indicated by the
dashed lines, as these are for the retractable landing
gear rails.
