If you are using a computer radio, you can easily center the two
servos through the radio's program for that function.
While the radio is still on, determine if the servos are moving the
correct direction to provide "left" and "right" aileron movements
when installed in the wing panels. For reference, "right" aileron
stick movement on the transmitter should move the right aileron
upward and the left aileron downward. If the direction of travel is
incorrect, reverse the action of the servos through the transmitter.
Doing this may re-center your servos a little. If so, re-center the
servo arms on the servos to 90
O
.
With the servo arms now
centered and the servos moving in the correct direction, install and
tighten the output arm retaining screws into both servos.

7) Plug a 24" servo extension lead into each aileron servo
plug and secure the connections with plastic tape. Reach into the
servo bay in the wing panel and pull the scrap piece of wood with
the string tied to it out of the opening. Remove the scrap piece of
wood and tie the end of the string securely onto the end of the
servo lead extension. Double check to be sure you are mounting
the right hatch into the right wing panel.
Reach into the oval hole at the center, front of the wing panel and
remove the scrap piece of wood with the opposite end of the
retrieval string tied to it (tweezers or needle nose pliers might be
handy in doing this).
Begin routing the servo extension lead
through the wing by lightly pulling on the inboard end of the string
while feeding the cable extension end into the hole inside of the
servo bay. Continue pulling the lead through the wing until the
servo extension plug is fully out of the exit hole, while seating the
servo hatch in place. Remove the string from the plug and use a
piece of tape to hold the servo lead to the bottom of the wing for
now.
Both aileron servo hatches are now secured in place into each
wing panel, using the eight #3 x 10mm PWA head screws.

8) From the kit contents, locate the Control Surface Hardware
Parts bag and the Pushrod Assemblies bag. From the Pushrod
Assemblies bag, remove the following:
❑
2 each
#4-40 x 4-3/8" Aileron Pushrods, Threaded One-End
❑
2 each
#4-40 R/C Links
❑
2 each
#4-40 Solder Links
From the Control Surface Hardware Parts bag, remove the
following:
❑
2 each
Nylon Control Horns
❑
4 each
#3 x 12mm PWA Control Horn Mounting Screws
The two #4-40 solder links are now soldered to the unthreaded
ends of each #4-40 x 4-3/8" pushrods. To make this easy, quick
and strong, we highly recommend using Stay-Brite

Silver Solder
and flux - available at most hobby shops. You will also need a good
soldering iron (25W or better) or gun. Lightly sand the unthreaded
end of both pushrods, where the solder link will be positioned. This
tends to make the solder joint even more secure. The secret to
