47. Glue in the balsa wing gussets WG1,
WG2, WG3, and WG4 in the four
corners of the wing panel.
48.
Glue a 1/16"x1/4" balsa cap strip along
the inside of the W1 wing rib. It should
be flush with the top edge of the rib.
49. Cut to length and glue in position the
1/8" sq. balsa Tip Braces. (see the
photo)
49.
Use a 90 deg. triangle to mark the locations of the 1/16" od x1/4" Aluminum Tube
Rigging Points (10 per wing panel) onto the faces of the appropriate wing ribs.
Glue the rigging points to the ribs at those locations. Be careful not to get any
glue inside the tubes.
Note: The two Rigging Points on rib W1 must be installed thru the 1/16"x1/4"
balsa cap strip.
50.
When dry, the entire wing can be removed from the building board. Double check
all the joints for adequate glue and apply a little more if necessary. Clean up any
rough edges with a fine grit sanding block.
Repeat Steps 46 through 50 to construct the opposite wing panel.
51.
Use a sharp #11 hobby knife to make 3/8" dia. holes in the fuselage side
sheeting where the trailing edges of the wings will be mounted. Make sure the
bottom of the hole is flush with the top of the rear dihedral brace RDB.
Tip: Before starting the hole, locate the top edge of RDB precisely on the outside
of the fuselage by pushing a pin thru side sheeting from the inside. Then, mark
and cut the 3/8" dia. hole from that point. Also, due to the fragile nature of the
side sheeting, it’s best to make the hole undersize first, and then, gradually open
it up closer to finished size. Finish shaping and sizing the hole with sandpaper
wrapped around a scap of 1/4" dowel.
52.
Sand the outside of the four 1/4" id x1" Aluminum Wing Mount Tubes with 220
grit sandpaper to improve glue adhesion. Then, slip the wing mount tubes onto
the root ends of the leading and trailing edges of both wing panels.
Now, trial fit one of the wing panels to the fuselage, resting the wing mount tubes
in position against the FDB and RDB dihedral braces in the fuselage. When you
have the wing panel lined up properly, have a helper put a single drop of thin CA
glue between the aluminum tube and dihedral brace. Don’t over glue at this point
or the excess glue might seep inside the tube, permanently gluing your wing
panel into the tubes.
After tack gluing both the front and rear tubes to the dihedral braces, have your
helper slowly pull the wing out of the tubes, while you continue to hold pressure
against the tubes, keeping them from breaking loose. After the wing is removed,
re-glue the wing mount tubes securely to the surrounding fuselage structure with
medium or slow CA. Avoid getting any glue inside the aluminum tubes.
