hitting the side of the holes in the wing ribs. Gently work the string
back and forth from both ends until the plug fits through the hole.
Sometimes the servo plug comes through all the ribs the first time
without getting hung up, and other times it seems like it gets hung
up on every rib. Be patient and don’t try to force it. The holes in
the ribs are large enough to get any common servo plug through.
Sometimes it helps to hold the wing panel vertically (center end
down) and shake it slightly while pulling lightly on the string.
❑
4) After you get the end of the servo wire all the way through
the wing, tape the loose end of the wire to the wing's top surface,
so that it won't fall back inside the wing.
❑
5) Fit the servo into the plywood servo mount that is built into
the wing panel. Note that the servo should be positioned so that
its output arm is at the rear end, toward the trailing edge of the
wing. Take up any slack in the servo wire as you insert the servo
by pulling on the end of the cable where it exits the top of the wing.
Use a small drill bit to drill small pilot holes in the servo mount for
the servo mounting screws. Use the screws supplied with your
radio system to mount the servo securely in place on the servo
mount. Repeat this proceedure to mount the servo in the opposite
wing panel.
WING ASSEMBLY, PART II: Joining the wing panels:
For the following steps you will need these parts:
•
1 - Right Wing Panel
•
1 - Left Wing Panel
•
1 - Hardwood Wing Joiner
❑
1) Trial fit both wing panels onto the Hardwood Wing Joiner.
Check to see that the wing panels fit together in proper alignment,
and that both root ribs come into firm contact with each other. If
the Hardwood Wing Joiner requires a little trimming to achieve this
fit, do so now. When satisfied with the fit, take back apart.
❑
2) Use Sig slow drying epoxy glue to permanently join the two
wing panels together. Apply the glue generously to the end ribs,
Work some glue into the joiner slots, and coat the joiner itself.
Carefully slide the wing panels together on the joiner. Press them
together tight. Wipe away any excess epoxy that oozes from the
joint with a paper towel or a rag dampened with rubbing alcohol.
Be careful that the leading and trailing edges of the two wing
panels are perfectly aligned and that there is no built in twist.
Secure the joint in perfect alignment with tape until the glue dries.
NOTE: It's very important to use plenty of epoxy when gluing the
wing panels together. The strength of your wing joint depends on
it! Don't worry if the excess glue oozes out and gets on the
covering material. With slow-drying epoxy, you will have plenty of
