Because the aileron servos are already installed and ready, the
installation of the rest of the radio system only consists of dropping
in the rudder, elevator and throttle servos, the receiver, and the
switch. The pushrod connections to these servos will be made
shortly. Install the rubber grommets and eyelets supplied with your
radio system onto the rudder, elevator, and throttle servos. Install
all three servos in place into the fuselage servo tray, again using
the screws supplied with your system.
Route the servo leads
through one of the half round receiver retention holes. We have
found it handy to label these leads for easy identification when
plugging them into the receiver.
The on/off switch can be mounted wherever it is most convenient
for you. If you want to have the switch exposed on the fuselage
side, you must cut a small rectangular slot for the switch body and
mount it with the hardware supplied with the radio system. We
always prefer an internally mounted switch and in this model it is
easy to locate and install. We place the switch on the floor of the
fuselage, just behind the landing gear block. With the switch in
place, we use a length of .046" music wire to activate the switch
from the outside of the fuselage.
Whatever switch mounting
method you choose, make sure the switch is securely in place
without any pressure on the wires.
The receiver is now mounted in place. As shown, it sits atop the
servo tray, ahead of the throttle servo and between the two half-
round cut-outs.
First feed the receiver's antenna through the
internal antenna tube (it exits at the bottom rear of the fuselage).
Use the remaining foam pad to cut top and bottom foam pieces,
sized to your receiver. Place one piece of foam on the bottom of
the receiver and the other on the top. Use a tie-wrap through the
two half-round cut-outs to secure the receiver to the tray.
Remember that the aileron servo leads will be coming into each
fuselage side, at the receiver location. Final placement of the
receiver and its servo receptacles should be made with this in
mind.
Use the remaining piece of foam rubber to pad your airborne
battery pack. Wrap the pack securely with the foam and hold it n
place with small rubber bands or tape. The final location of the
battery pack will be determined during final balancing when the
correct CG is established. For now, tuck it underneath the servo
tray or behind the tank to keep it out of the way.
PUSHROD ASSEMBLY & CONNECTION:
From the kit contents locate the following:
2 - 1/8" O.D. x 22" nylon rudder and elevator pushrods
1 - .065" dia. x 18" braided throttle cable
2 - 2-56 x 1-1/4" rods, threaded one end - rudder and elevator
servo control rods
2 - 2-56 x 3-1/2" rods, threaded one end - rudder and elevator
control horn rods
3 - 2-56 solder links
3 - 2-56 nylon R/C links
1 - 2-56 x 3/4" threaded brass coupler
2 - Nylon control horns - one right and one left for elevators and
rudder
4 - #2 x 1/2" pan head screws - control horn attachment
You will also need three servo output arms for your servos and be
sure your radio system is charged and ready to use for this
section.
❑
1) Use your soldering iron to solder the 2-56 x 3/4" brass
coupler onto one end of the braided throttle cable. Next, solder the
unthreaded ends of the two 1-1/4" rudder and elevator servo
control rods into two of the 2-56 solder links.
❑
2) Insert the unthreaded end of the 3-1/2" control rod into one
of the 18" nylon control tubes, up to the threads on the rods.
Thread the rod into the tube about 3/16" - 1/4".
Repeat this
procedure with the remaining tube and rod. Thread a nylon R/C
link onto the exposed threads of each rod - these are the ends that
will be attached to the rudder and elevator control horns.
