WING ASSEMBLY, PART III: Hinging the ailerons
For the following steps you will need these parts:
•
The wing assembly
•
1 - Right Aileron
•
1 - Left Aileron
•
10 - CA Hinges (5 per aileron)
❑
1) Start by inserting CA Hinges into the 5 slots in the trailing
edge of one side of the wing. Slide the hinges HALFWAY into each
hinge slot. DO NOT GLUE THE HINGES AT THIS TIME!
❑
2) Now install the aileron onto the exposed half of the hinges.
It's easiest to slip the aileron onto the hinges at angle, one hinge
at a time, instead of trying to push it straight onto all the hinges at
once. Start at the wingtip, inserting the end hinge into the end slot
in the aileron. Once you have that hinge started, move to the next
hinge and get it started into its slot. Move on down the line until
you have all five hinges started. Then you can finish pushing the
aileron up against the back of the wing. Don't be overly concerned
if the hinges don't end up perfectly straight or perfectly centered in
the slots - approximately halfway is good enough. AGAIN, DO
NOT GLUE THE HINGES IN AT THIS TIME!
❑
3) To set the proper amount of gap between the aileron and the
wing, simply deflect the aileron to the maximum amount of travel
needed. This will automatically set the proper hinge gap! Keep in
mind that for best control response the gap should be kept as
small as possible, but big enough to allow full movement of the
control surface.
Make sure everything is functioning properly
before proceeding to the next step.
❑
4) Flex the aileron downward, exposing the hinges between
the wing and aileron. Carefully place 3-4 drops of Thin CA glue
directly onto each hinge in the gap. You will notice that the glue is
quickly wicked into the slot as it penetrates both the wood and the
hinge. Turn the part over and apply 3-4 drops of glue to the other
side of each hinge. Keep a rag handy to wipe off any excess glue.
Note: We recommend using a fine-tip applicator on your CA glue
bottle. If you happen to get glue smears on the plastic covering,
don't worry about them right now. Once the glue is dry, you can
clean the glue smears off the covering with CA Debonder.
❑
5) Allow at least 10 minutes before flexing the aileron. After
sufficient time has passed, flex the aileron up and down several
times. 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 few
times. Also, pull on the aileron at each hinge location to make sure
all the hinges are securely in place. Repeat this process to attach
the other aileron to the other wing.
WARNING: The CA hinges provided in this kit are made of a
special absorbant material that can only be glued with Thin CA
adhesive. Thin CA (any brand) is the ONLY type of glue that can
be used on these hinges - do not use epoxy or any other type of
glue! Also, never use CA Accelerator on CA Hinges!
It's critical that you only make one application of glue to each side
of a CA Hinge! If you apply additional glue after the first application
of glue is dry, the second application of glue will merely puddle in
the hinge gap and make the hinge too stiff to operate. The excess
glue could also weaken the hinge! When properly glued, the part of
the hinge that you can 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 slot. A wet appearance
indicates that excess glue is puddled in the hinge gap. Three to four
drops of Thin CA is the right amount.
WING ASSEMBLY, PART IV: Install Control Horns & Pushrods
For the following steps you will need these parts:
•
The wing assembly
•
2 - Nylon Control Horns & Retainer Plates
•
4 - M2 x 15mm Phillips-Head Bolts
•
2 - Wire Aileron Pushrods
•
2 - Metal R/C Links
❑
1) Use a straight edge and a fine line marker to draw a guideline
on the aileron which lines up with the last hole in the aileron servo
output arm. This line should be 90
O
to the hinge line of the aileron.
❑
2) Set a Nylon Control Horn in place on the bottom of the
aileron. The front edge of the horn's base should be located at the
front edge of the aileron leading edge bevel. The upright arm of
