can be used to accurately place and center the hinge equally into
both the wing panel and the aileron. To do this, use a business
card and a pair of scissors to cut some "wedges". These should
be wide enough at the top so as to not pass through the hinge slot
cut-out. Insert each hinge in place into the wing panel up to the
cardboard wedge.
Now, slip the aileron onto each hinge, pressing it fully in place.
Center the aileron, leaving equal spacing between each end of the
aileron and the wing.
❑
2) Flex the aileron down a 1/2" or so to expose the center of
the hinge and use a piece of masking tape to hold it in this
position. Remove the wedge from one of the hinges and apply
three drops of thin CA to each exposed side of the hinge. Repeat
this operation until all the hinges on this side of the wing are glued.
IMPORTANT: - Be careful to avoid getting glue on the covering.
Solvents such as CA debonder will also remove the ink on the
covering.
❑
3) Remove the tape holding the flexed aileron, returning it to
the neutral position. Turn the wing over and flex the aileron down
about 1/2", again exposing the center of the hinges. Use another
piece of tape to hold the aileron in this position. Repeat the same
gluing process on each hinge - 3 small drops of thin CA on each
exposed side of each hinge. Remove the tape holding the aileron
and return it to the neutral position. Hold the wing up to the light
and look through the gap between the aileron and the wing for any
excess glue that may have accumulated in the gap.
Inserting a
slip of paper into the hinge gap, on each side of the hinges, will
wick out any excess CA glue. Hinge the opposite aileron using the
same procedure.
Note that it typically takes a little time for CA glue to fully "wick" its
way across the surface of the hinge and surrounding wood. Allow
about 10 minutes or so before flexing the ailerons. After sufficient
time has passed, firmly flex each aileron briskly up and down to
create free and easy movement. We also suggest pulling on the
aileron at each hinge location, making sure each hinge is firmly in
place.
❑
4) Remove the four screws from each corner of both aileron
servo covers on the bottom of the wing. With the aileron servo
covers out of the way, remove the covering from the slot that has
been cut for the servo arms.
❑
5) Install straight servo arms onto two HS-55 servos, orienting
the arms at 90
O
to the servo body. Note that these extra arms
come with the servos and are about 1-7/32" long, end to end.
❑
6) Lay the servo onto the inside surface of the aileron hatch,
positioning the servo arm centered in the slot, with the servo body
within the borders of the hatch. Hold the servo in this position and
use a pencil to mark where the bottom of the servo mounting lugs
and sides of the servo case meet. This marks position of the two
wooden servo mounts.
❑
7) Locate the four 8 mm square x 12 mm long hardwood
blocks from bag #15. These are glued on end, to the servo hatch,
at the location marks just made. 5-minute epoxy or thick CA glue
works well for this purpose. Allow the glue to fully set.
❑
8) Place the servo back onto the hatch between the two
mounting blocks. Use a sharp pencil to mark the servo mounting
Important Note: When installing CA type hinges, more is not
better! Applying excess thin CA glue to this type of hinge does
nothing more than stiffen it, potentially causing the hinge to
crack and break. If you have followed these instructions, each
hinge will have a total of 6 small drops of thin CA glue on each
side. This is the correct amount of adhesive for the purpose.
Using a fine tip applicator for this purpose is strongly advised
and recommended.
