We can now install the
radio receiver. In the master bag you will find the plastic
antenna tube. Attached to the tube you will find a small bag
containing the #6338 antenna mount, one #6922 4-40 x 1/2"
FHSScrew and the black antenna tube cap (see fig. 179).
Before we mount the receiver we need to assemble and
install the antenna mount. Take one end of the antenna tube
and push it into the antenna mount. Cut the antenna tube so
that it is about 15 inches long.
We are going to install the radio receiver on the right
side of the chassis. Near the back of the chassis on the right
side you will find one hole which is counter sunk on the bottom
of the chassis. This is our recommended antenna mounting
location. Mount your receiver forward of this location. You
need to make sure that the servo plug from the steering
servo, throttle servo (or ESC) can easily reach the receiver.
We also want the antenna wire to have a clear run to the
mounting location for the antenna mount. Take out one of the
double stick tape strips (also know as servo tape) from the kit
bag. Ball bearing kit owners will have already done this in fig.
178. Cut a piece to fit on the bottom of the receiver case.
Racers Tip: Team drivers will sometimes use two layers of
servo tape to help provide better shielding from electrical
interference.
Fig. 180 shows the receiver installed, with the an-
tenna wire run through the antenna tube and the antenna
mount ready to be secured to the chassis with the #6922
screw. You want a couple of inches of the antenna wire
coming out the top of the antenna tube. Now push the black
antenna tube cap over the end of the tube and the antenna
wire. This will prevent the antenna tube from pulling out
during a race.
Racers Tip: Keep the antenna tube as long as
possible for radio range (about 15 inches or so), but not to the
point where it could get caught in the wheels or some other
else. WARNING! Do not cut the radio receiver antenna
wire. Cutting this wire could detune the receiver, caus-
ing severe radio interference or glitching problems.
Each receiver is tuned to the length of antenna wire that
comes attached to it. If you have excess antenna wire, the
appropriate way to store it is to wrap the excess around a
piece of cardboard or plastic as shown in fig. 181. Make sure
the antenna wire does not cross over itself. This can make the
antenna act as a shorter antenna and reduce the radio
receiving range. You should mount the excess coiled an-
tenna on top of the receiver with a piece of servo tape.

Do not cut your antenna wire. Wrap any excess wire
around a piece of cardboard or plastic cut as shown. Do
not let the antenna wire cross over itself.

Now we can connect the steering servo and
speed control plugs to the receiver. We will start by inserting
the steering servo plug into the channel 1 (or rudder) slot on
the receiver. You can coil the servo wire or bundle the excess
and secure it with a wire tie supplied in the kit. If you decide
to coil the wire you can wrap it snugly around a pencil. If you
bundle the wire keep the bundle close to the servo to help
prevent any interference problems. Next we need to install
the throttle servo or ESC plug into channel 2 (or throttle) on
the receiver. Route the servo wire (from the speed control)
across the chassis so that it will end up under the battery and
battery pad. Run it straight across not at an angle. We will
protect this wire in a moment.
