7) Plug the two servos into your radio receiver
and center them both. Make sure the aileron trim tab
on your transmitter is centered as well. Install the
rubber isolation grommets and brass collets onto both
servos. The collets should be installed with the flanges
towards the bottom of the servo.
q
8) Install a single long servo arm onto each of
the servos. The arms should be mounted 90º to the
centerline of the servos. See figure # 3 below.

9) Locate the two precovered aileron servo
hatches. Turn each of the two hatches upside down
(non-covered side) and you will notice precut oval
holes. Using a modeling knife, remove the covering
from over the two holes. These holes are where the
servo arms will exit and actuate the ailerons.
q
10) Working on the bottom of one servo hatch
for now, place one servo onto the hatch. The servo
arm should be inserted through, and centered in, the
precut hole. Notice the hole is angled. Make sure the
servo is parallel to the hole.
q
11) Holding the servo in proper alignment on
the hatch, temporarily place two of the 8mm x 15mm
x 20mm wood blocks in place behind the servo
mounting tabs. The blocks are positioned vertically
with the taller side up. See photo # 1 below.

q
12) Using a pencil, outline the locations of the
two hardwood blocks and the servo onto the bottom
of the servo hatch.
q
13) Remove the parts from the hatch. Using
Kwik Bond 5 Minute Epoxy, glue the two wood
blocks into place on the servo tray. Allow the epoxy
to fully cure before proceeding.
It is important that you use epoxy in this situa-
tion. C/A glues will not adhere as well to the
hardwoods, and if used, the blocks could break loose
when installing the servo, or worse, during flight.
q
14) After the epoxy has cured, place the servo
back onto the hatch. Mark the locations of the four
mounting screws onto the two blocks using a pencil.
q
15) Remove the servo and drill 1/16” pilot holes
through the blocks for the servo mounting screws.
Drilling pilot holes into the wood before install-
ing the screws is important. It will keep the
wood from splitting when the screws are installed.
q
16) Place the servo back onto the servo hatch
and secure it in place with the mounting screws. Re-
peat steps # 10 - # 15 for the second aileron servo.
On the bottom of each hatch place a mark so you know
which one is for the right and which one is for the
left. This will help keep you from mixing them up.
INSTALLING THE SERVO HATCHES

17) Turn one wing panel right side up. Using a
modeling knife and a razor saw, remove the portion
of the root rib above the precut servo exit hole and
cut a half circle in the top of the wing to allow the
servo wire to pass through. See photo # 2 below.

q
18) Attach one 12” aileron extension to one
servo lead. Cut one 1-1/2” length of heat shrink tub-
ing and slide it over the servo lead. Place the tubing
over the servo plugs where the lead and the extension
are connected. Shrink the tubing using a heat gun to
secure the plugs securely. See figure # 4 below.
