the hinge. Continue this process until you have glued both sides
of all the elevator hinges. Keep a rag handy to wipe off any excess
Thin CA glue.
Note: If you get some glue smears on the plastic covering, don't
worry about them right now. Once all the hinges are glued, you
can go back to clean the smears off with a little CA Debonder on
a rag or paper towel.
Let the glue dry a minimum of 10 minutes before flexing the
hinges. At first you might notice a little stiffness in the joint. This
will go away after the hinges have been flexed back and forth a
couple dozen times.
VERY IMPORTANT:
It's critical that you only make one
application of glue to each side of a CA hinge.
If you apply
additional glue to the hinge after the first application of glue is
already dry, the second application of glue will merely puddle in the
hinge gap and make the hinge too stiff to operate properly. The
excess glue can also weaken the hinge! When properly glued, the
portion of the hinge that you see in the hinge gap should have a
dry appearance, not wet. A dry appearance indicates that almost
all of the glue has properly soaked into the hinge and wood. A wet
appearance indicates that excess glue is puddled in the hinge gap.
Excess glue can become brittle with age and cut the hinge. Also,
NEVER USE CA ACCELERATOR (KICKER) ON CA HINGES!
❑
11) Hinge the rudder to the back of the fin/fuselage with three
CA Hinges, in the same manner that you did the elevators.
❑
12) Hinge the ailerons to the back of the wing with four CA
Hinges per aileron. Use the same proceedure you did for hinging
the elevators and rudder.
LANDING GEAR
❑
13) Notice that one of the landing gear wires is taller than the
other. The taller wire installs in the upper hole in the fuselage side,
and the shorter wire goes into the 2nd hole down. Insert the wires
in the holes, one wire on each side of the fuselage, (it doesn't
matter which wire goes on which side of the fuselage).
❑
14) Secure the wires to the fuselage with the two Plastic Tie
Straps provided. Snug the tie straps as tight as possible and then
cut off the excess length.
❑
15) Main wheel installation:
a) Slide one of the Nylon Wheel Spacers onto the axle of the
landing gear wire.
b) Put the Wheel on the axle.
c) Install the Wheel Collar on the axle up close to the wheel,
but not actually touching it. Leave a little room so the wheel
can turn freely. Tighten the wheel collar set screw.
d) Repeat steps a, b, and c to install the opposite wheel.
CONTROL HORNS
❑
16) Prepare the four Nylon Control Horns for installation:
a) Drill out the 3 holes in each horn with a 3/64" or #56 dia.
drill bit, so that they will accept the pushrod wires.
b) Use a sharp razor blade or hobby knife to cut the 2 pegs on
each control horn to approximately half of their original
length. This is done to insure that the pegs don’t protrude all
the way through the control surfaces.
❑
17) Install a Nylon Control Horn on top of the left elevator:
a) Begin by using a sharp blade to remove the small strip of
covering material between the 2 holes that are pre-drilled in
the left elevator for the control horn.
b) Apply a small drop of Thick CA glue to the two pegs and to
the bottom of the base of the control horn.
c) Firmly press the horn into the two pre-drilled holes in the
elevator, until the base of the horn bottoms out on the
elevator surface. If any glue oozes out onto the covering, it
can be easily removed with CA Debonder, after the glue dries.
