Step 4.
Insert the servo with the 13" extension into the aileron
cutout on the bottom of the wing closest to the wing root, as shown
below. Be sure the output shaft is oriented toward the trailing edge
of the wing. Insert the second servo with the 18" extension into the
servo cutout located closest to the wing tip. Allow the servo leads to
exit the root of the wing. Refer to the photo below.
Note:
The servo wiring method is to be used if a computer
radio is used with Flapperon mixing (recommended). In
this case the Y-harnesses are plugged directly into the
receiver using the aileron and appropriate auxiliary channel
used for flapperon mixing (see your radio’s instructions).
If a non-computer radio is used, then three Y-harnesses and two
12" extensions are required. In this case each of the two servos
should be plugged directly into a Y-harness and a 12" extension
connected to the Y-harness. This lead will exit the root of the wing.
Step 5.
Using the screws included with the servos, fasten the
servos in place. You may find it helpful to drill a 1/16" pilot hole
before installing the screws.
Step 6.
Remove the stock arms and replace with Heavy-Duty 1"
Servo Arms (HAN3574 JR or HAN3575 Futaba) to give the needed
control throws and to handle the increased loads of the large
surfaces. The arms need to face outward toward the wing tips as
shown in the photo below. Be sure to use a drop of Blue Locktite
to secure the servo arm screws if using metal-geared servos.
