taping it to the wing panel in the flexed position. Turn the panel
over and apply four drops of CA glue to each edge of the hinges.
Remove the tape, returning the aileron to its centered position.
Because it takes a little time for the CA to fully wick its way through
the entire surface of the hinge and surrounding wood, allow at
least 10 minutes before flexing the aileron. Any spilled glue can be
easily removed with SIG Debonder.
After sufficient time has passed, flex the aileron firmly up and
down on the wing panel to create free and easy movement. We
also suggest pulling on the aileron at each hinge location to be
sure they are firmly in place.
Repeat this procedure for the
remaining wing panel and aileron.

6) The aileron pushrods are now assembled.
From the kit
contents locate the two 2-56 x 4-1/2" wire pushrods - threaded at
one end, two nylon 2-56 R/C links, two 2-56 solder links. You will
also need a soldering iron and solder.
Slip a solder link onto the unthreaded end of the 4-1/2" aileron
pushrod wire until you can just see the end of the wire emerge
from the link's tube - a distance of about 3/8". Solder the link in
place to the wire, using enough heat to "sweat" the joint
completely. Make the second aileron pushrod in the same way.
Thread the nylon R/C link onto the threaded end of the pushrod,
about half the distance of the threads. The pushrods are now
ready for installation.

7) The aileron control horns are now installed. From the kit
contents, locate the two smaller nylon control horns and four
#2 x 1/2" Slotted Pan Head screws. Note that there is a left and
right aileron control horn.
When mounting the horns to the
ailerons, the bases of the horns will each face out towards the wing
tips. We suggest using servo output arms for the aileron servos
instead of the round wheel types. For this step, these arms should
be mounted onto each aileron servo, with the arm facing inboard
toward the fuselage, at 90° to the servo.
Attach the solder link to the outer-most hole in the servo output
arm and place the arm back onto the servo in the correct position
(facing inboard at 90° to the servo). Place the nylon aileron horn
onto the leading edge of the aileron, with it's holes lined up with the
hinge line. The upright arm of the horn should be parallel with the
servo. In this position, use a pencil to mark the two mounting hole
locations in the horn's base onto the surface of the aileron. Use a
power drill and a 3/32" dia. drill bit to make two holes through the
aileron. The horn can now be attached to the aileron using a small
screwdriver and two #2 x 1/2" Pan Head screws. These screws
should slip through the horn base and the drilled holes and into the
separate nylon horn piece. Tighten the screws securely. Repeat
this process on the opposite aileron. Use diagonal cutters or a
small grinding wheel to remove the exposed tips of the screws on
top side of each aileron.
The nylon R/C link on the aileron pushrod can now be attached to
the aileron horn. We typically use the second hole from the horn's
tip for initial placement. With the servo and aileron now connected,
the nylon R/C link can be adjusted to position the aileron in
approximately "neutral". Final adjustments will come later.

8) From the kit contents, locate the two threaded J-hooks.
These will be threaded into the wing panel root ribs to provide wing
retention using a #64 rubber band. 1/16" dia. guide holes have
been pre-drilled in each wing root for these hooks, just ahead of
the main wing tube holes. Once you locate the holes, use a 3/32"
dia. bit and a power drill to drill through the root rib.
Pressing the J-hook firmly into the hole, begin threading it in place
using hand pressure.
Once the threads engage, continue
threading the hook in place until it is about 1/2" away from the
surface of the wing root rib with the open end of the hook facing
forward. This is the correct position for these hooks. Unthread the
hooks, removing them from the wing panels. Mix a small amount
of 5-minute epoxy and use a small length of wire or a pin to get
glue into both of the hook holes. Apply a small amount of glue to
the threads of the hooks and thread them back in place into each
