Figure 1 Figure 2

The transmitter (Tx) requires 4 “AA” batteries. Do not mix old and new cells. Do not mix alkaline, standard or rechargeable
batteries. To install the batteries, slide open the battery door on the bottom of the Tx (see figure 1). Install the batteries in
the holder following the configuration molded into the case, making sure to note the proper polarities on each cell. Close the
battery door.

Turn the Tx power switch on (see figure 2). The “BATT” LED should illuminate. If not, turn off the Tx and check the configuration
of the batteries to make sure each cell is firmly in place and in the proper direction. If the red LED blinks, the batteries are low
on power and should be replaced. DO NOT OPERATE AN R/C VEHICLE WITH LOW BATTERIES AS IT COULD RESULT
IN REDUCED RANGE AND POSSIBLE LOSS OF CONTROL OF THE MODEL.

During normal operation, always keep the Tx antenna in the up position.

SERVOS Because there are a variety of specific applications
for servos in R/C modeling, different servos are designed for
different applications. For each servo, use a servo horn long
enough to accommodate the entire range of movement for that
particular control.

RECEIVER, SWITCH HARNESS AND RECEIVER BATTERY

Insert 4-AA alkaline batteries into the receiver battery holder in the
direction shown on the battery holder. After the servos and receiver
are mounted into your model per the model’s manual, connect the
servos and switch harness to the receiver where shown. The servo
connectors are polarized to prevent improper connection. Pay close
attention when connecting them to the receiver. If you are using
an electronic speed control (ESC), connect the ESC’s throttle lead
to channel 2 in the receiver and refer to the ESC’s instructions for
further set-up details (the battery holder and switch harness should
be omitted when using an ESC). Center the steering and throttle
trim adjustments (see figure 2) before installing servo horns.

Figure 3

Bind the Transmitter to the Receiver

1. Turn on the transmitter.

2. Turn on the receiver. If the receiver is not bound, the LED light will not be on.

3. Push and hold the bind button on the receiver until the light glows red and then off (about one second).

4. Release the bind button.

5. If the binding is successful, the LED will flash once and then remain ON.

You are ready to go!

System Check

Turn on the Tx, then the Rx. Make sure all
servos operate according to the movement
of the Tx controls.

STEERING Move the steering control left
and right. Be sure there is no binding and
that the steering controls move in the proper
direction (see figure 4). If the steering wheel
is turned to the right but the model turns left,
move the steering reversing switch to the “R”
position, and vice-versa.

Figure 4

STEERING RATE This adjustment (see figure 4), is used to fine tune the steering servo throw. The steering rate knob

allows you to increase/decrease the amount of steering travel.

THROTTLE Squeeze the throttle trigger. If the throttle servo moves in the wrong direction, move the throttle reversing
switch to the “R” position. (See the model’s instruction manual for specific set-up instructions.)

Troubleshooting

Problem Possible Cause Solution

Range

is short

Run time

is short

Tx LED is steady

but the servos

do not funtion

Interference

or servos

glitching

One glitching servo

Interference Check frequencies in the area, check Rx installation

Low Tx or Rx battery Replace the batteries

Crash damage Send the radio to Hobby Services for repair

Rx batteries need to be replaced Replace the batteries

Rx switch in the off position Tu rn on the switch harness

Switch harness is
connected incorrectly

See the quick
reference guide

Out of range Operate closer

Servo is bad Send the servo to Hobby Services for repair

Outside interference
(Pagers, transmission towers, etc)

Check your local R/C club for confirmation
of dangerous frequencies in your area

Rx is not properly bound Follow the instructions for binding

Low Tx or Rx batteries Replace the batteries

Binding servos causing
excess battery drain

Free the binding components in pushrods
or moving surfaces, see model’s manual
