Install The Aileron Servos And Pushrods - GREAT PLANES Matt Chapman Cap 580 Instruction Manual

Install the Aileron Servos and Pushrods

1. For the servo installation a Y-harness connector is
required and is used to allow the aileron servos to plug into
one slot in your receiver.You may have a computer radio that
allows you to plug the servos into separate slots and mix
them together through the radio transmitter. If you choose to
mix them with the radio rather than the Y-harness, refer to
the instructions with your particular brand of radio.
2. Located in the wing in the aileron servo compartment,
a string is taped to the wing skin. Tie the string to the end of
the servo wire. Pull the servo wire through the wing with the
string. Feed the servo wire out the hole in the top of the wing
center section. Tape the servo wire to the wing to prevent it
from falling back into the wing.
3. Install the servo into the servo opening. Drill
through the servo mounting holes with a 1/16" [1.6mm] drill
bit. Remove the servo from the servo opening. Install and
then remove a servo mounting screw into each of the holes
you have drilled. Apply a drop of thin CA into the holes to
harden the threads. Once the glue has hardened install the
servo into the servo opening using the hardware included
with your servo. Center the servo, then install a servo arm
pointing towards the wingtip.
4. Position a large nylon control horn on the aileron,
positioning it as shown in the sketch and aligning it with the
servo. Mark the location for the screw holes. Drill through the
marks you made with a 1/16" [1.6mm] drill bit, drilling
through the aileron. Secure the control horn to the aileron
with two 2-56 x 3/4" [19mm] socket head cap screws and the
nylon mounting plate.
5. Locate a .074" x 6" [1.9mm x 152mm] pushrod wire
threaded on one end. Screw a nylon clevis onto the
threaded end of the wire 20 full turns. Install a silicone clevis
keeper onto the clevis and then install the clevis in the
second hole from the end of the aileron control horn.
6. Be sure the aileron servo is centered. Enlarge the
first hole in the servo arm with a Hobbico Servo Horn Drill
(or a #48 or 5/64" [2mm] drill bit). Center the aileron and
align the wire pushrod with the hole in the end of the servo
arm. Using a marker, mark the location where the wire aligns
with the hole in the servo arm. On that mark make a 90
degree bend. From the bend measure an additional 3/16"
[4.8mm], then cut off the excess pushrod wire.

7. Install the wire into the hole in the servo arm using
a nylon FasLink as shown in the sketch.
8. Repeat steps 1-7 for the left wing panel.
