high temp material.) Then go over the entire airplane with a covering iron or a heat gun and a
rag. Heat the covering until it is tight and wrinkle free (it can take a lot of heat, but stay away
from the seams and “N” numbers as much as you can) and then quickly rub the covering down to
the wood with the rag. Once this is done the covering will stay tight and wrinkle free for quite a
while.
ASSEMBLING THE WINGS
ATTACH THE AILERONS TO THE WINGS. We recommend Pacer Hinge Glue for this
operation. Epoxy will work, but the hinge glue is water-base and much easier to use.
Glue the hinges into the aileron first. Make sure that the hinge will go in far enough that the
hinge pin is even with the point of the “V” on the leading edge of the control surface. Enlarge
the first 1/4” of the hinge hole if the “knuckle” of the hinge won’t go in far enough. Put a tiny
drop of light oil on the hinge pin and flex each
hinge a few times to work the oil in. Put glue
into the hinge hole in the aileron and lightly coat
one end of the hinge. Push the hinge into the
fixed surface until the
hinge pin
is just touching
the point of the “V”. Clean off any glue that
squeezes out of the hole.
Now, bend each hinge down 90 degrees and twist
it until it is perpendicular to the leading edge of
the aileron (looking from the front) and parallel
to the other hinges in the same surface. All of
the hinge pins must line up with each other and be perpendicular to the leading edge or the
control surface will bind up and not travel freely. Let the glue dry completely before proceeding.
Test fit the aileron onto the wing.
IMPORTANT:
The ailerons have hard points built in for the
control horns. Be sure to put the hard points on the bottom when installing the ailerons.
Enlarge the first 1/4” of the hole if needed. Try to keep the hinge gap down to 1/32” or so.
When you are happy with the fit, glue the hinges into the fixed surface. Clean excess glue out of
the hinge gaps with a wet paper towel and a
business card (rubbing alcohol if you used
epoxy). Set the wing aside to dry.
INSTALL THE AILERON SERVOS. Test
fit your servo in the aileron servo mount and
enlarge the opening if necessary. Attach an
18” extension to your servo and install a
piece of 3/8” shrink tubing over the
connection to be sure that it doesn’t come
loose.
