install the servo arm set screw and remove the
masking tape from the ailerons.
PARTS REQUIRED
RADIO INSTALLATION
INSTALLING THE SERVO TRAY
o
{1} Fuselage Servo Tray (D-15)
o
{2} Balsa Support Rails (D-30)
o
1) Trial fit the servo tray (D-15) in posi-
tion inside the fuselage. The tray should rest
on top of the preinstalled balsa supports glued
to the fuselage sides. The front edge of the
tray should be 1-1/4” behind the front bulk-
head. See photo # 31 below.

2) When satisfied with the fit, remove the
tray and mix up a generous amount of Kwik
Bond 5 Minute Epoxy. Glue the tray in place
using the epoxy. Before the epoxy sets, glue
the two balsa support rails (D-30) in place.
They are positioned on top of the servo tray,
directly above the lower support rails. Allow
the epoxy to cure fully before proceeding.
o
3) Install the rubber grommets and brass
collets onto your remaining three servos. Test
fit the servos into the precut servo holes in the
servo tray. The output shaft of the center servo
should be pointing towards the back of the
fuselage. The output shaft of the two outer

servos should be pointing towards the front
of the fuselage. See photo # 32 below.
Because the size of servos differ, you may
need to adjust the size of the precut open-
ings. You may also need to use a modeling
knife and cut a groove to allow room for the
servo wires.
o
4) Install the servos using the wood
screws provided with your radio system. Drill
1/16” pilot holes through the tray before in-
stalling the screws. This will help prevent the
wood from splitting.

INSTALLING THE RECEIVER & BATTERY
o
5) Plug the servo leads into the receiver.
Looking from behind the airplane the left servo
is the for throttle, the center servo is for el-
evator and the right servo is for rudder. Plug
the aileron extension and switch that came with
your radio system into the receiver as well.
o
6) Wrap the receiver and battery pack in
foam rubber to protect them from vibration.
Position them under the servo tray, using ex-
tra foam rubber to hold them in place.
Because of the length of the Ultimates
nose, the receiver and battery should be
positioned at the rear of the servo compart-
ment. This will be especially true if using a
four stroke engine.
INSTALLING THE SWITCH
o
7) Mount the switch to the fuselage side
at the rear of the servo compartment. Use the
faceplate of the switch itself to locate at make
the necessary cutouts and holes.
