hatch. Now lay the servo on the cover with the mounting lugs on
the wood blocks and mark through the center of the grommets
where the pilot holes for the mounting screws need to be drilled.
With a #50 bit, drill each pilot hole about 1/2" deep. The servos are
now mounted in place using the screws provided with your servos.
❑
5) The completed servo hatch covers, with the servos in place,
are now ready for mounting into the lower wing. Carefully insert
the servo cable into the leading edge of the servo bay ahead of the
spars and lower the hatch into position. If the stick of wood with
the string is in the way, break it loose and lay it in the servo bay for
now. Feel the covering on top surface of the wing above the servo
to make sure the servo is not in contact and causing an unsightly
hump. You may need to slide the hatch towards the leading edge
with some servos to get this clearance. Tape the hatch in place
with small pieces of tape and mark where to drill the pilot holes.
Use the pre-drilled holes in the hatch to locate these holes. Then
use a 1/16" bit to drill the pilot holes. Be careful when drilling not
to run the drill through the top of the wing.
❑
6) Remove the hatch and plug one of the 6" servo extensions
in on each servo. Because this connection will be buried in the
wing, secure the connectors with heat shrink tubing or tape. It is
now time to center both servos. Remove the servo arms and set
them aside. Plug the extensions into the "y" harness and the "y"
harness into the aileron socket of your receiver. Two 2mm x 36mm
aileron pushrods with a Z-bend on one end and a metal R/C link
on the other have been provided for the ailerons. Each pushrod is
pre-assembled at the factory.
Connect the Z-bend end of the
pushrod to the middle hole of the servo arm and through the exit
hole in the cover before proceeding to the next step. Turn on your
transmitter and center the aileron trim lever.
Now turn on the
receiver and let the servos neutralize before adjusting the servo
arms to position them as close to 90
O
to the side of the servo case
as possible.
With the servo arms now positioned correctly,
re-install the servo output arm screws. Turn off the radio system
and remove the servo leads from the Y-harness.
❑
7) The length of string in each wing panel has been factory-
installed to make it easier to pull the servo wires, with their
attached extension cords, through the openings in each wing
provided hardware, mount the nylon inter-connect horns in place
to each aileron.
The ailerons are now permanently hinged in
place, using the same procedure used on the top wing.
❑
4) Locate the bag with the aileron servo hatch covers, servo
mounting blocks, and screws. Note that there is a left and right
servo hatch cover. These fit into the servo bay with the pushrod
fairing towards the wing tip and the pushrod opening towards the
aileron. The pushrod exit needs to be opened up. Drill through the
angled surface with a 1/4" drill, then finish opening the exit with a
#11 blade and sand paper wrapped around a pencil or dowel.
Lightly sand the inside surface where the servo will sit to break
the glaze on the plastic.
Insert the grommets and eyelets in
the mounting holes of your servos as recommended by the
manufacturer. Now lay your servo on the inside of the hatch cover,
centering it from end to end and centering the output arm within
the pushrod fairing. Use a pencil to mark where both ends of the
servo and where the bottom of the grommets are.
These marks are where the servo mounting blocks (8mm x 20mm
x 20mm hardwood) will be glued to the hatch with epoxy. When
the glue cures, use a ruler to find the approximate center of each
block and mark the location on the plastic on the opposite side
from the block. With a 1/16" bit, drill a pilot hole at each mark
about 1/4" deep through the plastic into the wood block. Install a
M2 X 8mm PWA screw into each hole, securing the block to the
