o 1. If you have not done so already, remove the major parts
of the kit from the box and inspect for damage. If any parts
are damaged or missing, contact Product Support at the
address or telephone number listed in the “Kit Inspection”
section on the prevous page.
o 2. Carefully remove the tape and separate all the
control surfaces. Use a covering iron with a covering sock
on medium/high heat to tighten the covering if necessary.
Apply pressure over sheeted areas to
thoroughly bond the
covering to the wood.
ASSEMBLE ThE wINg
Install the Ailerons
Do the left wing first so your work matches the photos
the first time through. you can do one wing at a time, or
work on them together.
o o 1. Test fit the included hinge points into the pre-drilled
holes in the wing panel and aileron. The hinge points
should seat into the hinge holes all the way to the metal pin
in order to minimize the gap between the aileron and wing.
If necessary, use a hobby knife to enlarge the surface of the
hinge holes until the proper fit is achieved. Test fit the aileron
to the wing. The hinge gap between the aileron and wing
should only be wide enough to allow a small line of light
through. Excessive gap will decrease the effectiveness of
the ailerons.
o o 2. Apply a small amount of petroleum jelly or something
similar to the center of each hinge to prevent epoxy from sticking
to the joints and not allowing the hinge to operate smoothly.
READ ALL OF STEp 3 BEFORE pROCEEDINg.
o o 3. Mix up a batch of 30-minute epoxy. Using a toothpick
or wood scrap, apply epoxy to the inside of each hinge point
hole. The holes are drilled through to the open cavity in the
wing and aileron, so be careful that you do not apply too
much to the walls of the holes as it will simply drip into the
wing. Apply a light coat of epoxy to one end of all the hinges
for one wing panel. Insert the hinge points into the holes in
the wing panel, wiping away excess epoxy with denatured
alcohol as necessary. Be sure the hinges are inserted in the
correct orientation so that the direction of the hinge pin is
inline with trailing edge of the wing. Apply epoxy to the other
ends of the hinges and slide the aileron into position over
the hinges. Use masking tape to hold the aileron in place
while the epoxy cures.
o 4. Repeat these steps for the right wing panel.
