Warning
Conduct Tests
Prior to operation always perform a range test.
Even one abnormality in the R/C system may cause loss of control.
[Range Test Procedure]
Have a friend hold the model, or place on a stand where the wheels or prop can not
come in contact with any object. Collapse the transmitter antenna and operate from a
distance of about 100 feet. Be sure to check the movement of each servo to make sure
it follows the movement of the steering wheel and throttle trigger. If the servos do not
follow the commands from the transmitter or any type of interference is detected, Do
Not operate the model.
Fully extend the transmitter antenna.
If the transmitter antenna is not fully extended, range will be reduced and control may
be lost.
Prohibited
Do not operate two or more models on the same frequency at the same time.
Operation of two or more models on the same frequency at the same time will cause
interference and loss of control of both models.
AM, FM and PCM are different methods of modulation. Nonetheless the same frequency can not be used at the same point in time, regardless of the signal format.
Safety Precautions
Do not operate outdoors on rainy days
Never operate in the rain or run through puddles.
The transmitter, receiver, batteries and most servos, and speed controls are not waterproof. Contact with any type of moisture or immersion in water or snow will cause
damage along with possible loss of control. Should any type of moisture enter any
component of the system, immediately stop using the R/C system and return it to our
service center for inspection.
Prohibited
Do not operate when visibility is limited.
Should you lose sight of the model, a collision or other dangerous situation may occur.
Prohibited
Do not operate near people or roads.
Do not operate near high tension power lines or communication broadcasting antennas.
Prior to the operation of any model be sure the area you plan to use is safe. Be aware
of all objects that may be in the path of your model. Do not operate the model where
people or any type of moveable object could stray in the path of your model. Control
loss due to interference, component failure, loss of sight or low battery voltage could
result in serious injury to yourself and others as well as damage to your model.
Prohibited
Do not operate your R/C system within 1 mile of another site where radio control activity may occur.
Interference from other R/C systems will cause loss of control.

Page 5
Prohibited
Do not operate when you are tired, not feeling well or under the influence of alcohol or
drugs.
Your judgment is impaired and could result in a dangerous situation that may cause
serious injury to yourself and others.
Before you turn on the power switch on the transmitter, always check to see that the
Safety Precautions
trigger is at the neutral position. Always turn the transmitter on first, then the receiver.
When you turn the system off, always turn the receiver off first and then the transmitter. This step is very important. Always follow this procedure.
If this procedure is not followed, injury to yourself and others as well as loss of control
could occur.
Adjustment Note
Make all adjustments to the radio control system with engine not running, or the electric motor disconnected.
If the engine is running or the motor is connected while adjustments are made, the
model may run out of control.
Remove the main battery source from electric powered models when they are not
being used.
Should you accidentally leave the receiver switch on, the model could run out of control.
Caution

Do not touch the engine, motor, speed control or any part of the model that will generate heat while running.
Touching hot parts will result in serious burns.
Storage and Disposal Safety Precautions
Warning
(When using a Ni-cad battery to power your system)
At the end of a day's operation, store the system with Ni-cad battery discharged. Be
sure to recharge the system before it is used again.
You should fully discharge your system's batteries periodically to prevent a condition
called "memory". For example, if you only make two runs in a day or you regularly use
a small amount of battery's capacity, the memory effect can reduce the actual capacity
even if the battery is charged for the recommended amount of time.
Prohibited
Do not throw a Ni-cad battery into a fire. Do not disassemble or attempt to repair a Nicad battery pack.
Overheating, damage and acid leakage may lead to burns, loss of eye sight as well as
numerous other types of injuries. The electrolyte in Ni-cad batteries is a strong alkali.
Should you get even the smallest amount of the electrolyte in your eyes, Do Not rub,
wash immediately with water, and seek medical attention at once. The electrolyte can
cause blindness. If electrolyte comes in contact with your skin or clothes, wash with
water immediately.

Assembly Precautions
Warning
Check
Check the receiver, servos, and battery connectors, to be sure they are firmly connected.
If a connector is not fully inserted, vibration may cause the connector to work loose
while the model is operating. This will result in loss of control.
Check
Operate each servo horn over its full stroke and check to see that the linkage does not
bind or is not too loose.
Excessive force applied to the servo horn by binding or poor installation may lead to
servo problems and result in loss of control.
Assembly / Adjustment

Page 11
Prohibited
The receiver antenna may seem long. Do not cut or alter from the original length.
If the receiver antenna length is altered, the receiver will be adversely effected. The
receiver will become considerably more susceptible to interference and high frequency noise which will result in loss of range and control.
Installation Note
(Electric Cars and Boats)
Isolate the receiver from vibration by attaching to the chassis or mounting plate with
thick double sided tape.
(Gas Powered Cars and Boats)
Isolate the receiver from vibration by wrapping it in foam rubber or similar type cushioning material. Protect the unit from water damage by placing it in a plastic bag or
waterproof radio box.
The receiver contains precision electronic parts. These parts are vulnerable to vibration and shock. Any contact with moisture (water or condensation) may cause receiver
malfunction and loss of control.
Installation Note
Keep all devises that omit high frequency noise, such as motors, batteries, and wiring
that handles heavy current loads, at least 1/2 inch away from the receiver and the
receiver antenna.
High frequency noise will cause a decrease in operating range and could cause loss of
control.
Assembly / Adjustment
Use genuine Futaba parts only.
Use only genuine Futaba crystal sets as specified in this instruction manual.
The use of other than Futaba crystal sets will result in decrease of range as well as
loss of control. There are separate crystals for the Transmitter and Receiver. There
are also crystal sets for AM, FM and Dual Conversion FM. Use only single conversion
AM crystal sets with this system.
Changing crystals in 72-75 MHz transmitter is illegal. However, 27 MHz is allowable.
(For U.S.A.)
Install electronic speed control heat sinks as well as other components that conduct
electricity so they can not come in contact with aluminum, carbon fiber or other materials that conduct electricity.
If, for example, the speed control came loose while the model was running and
touched an aluminum chassis, a short circuit may occur that would cause irreparable
damage to the system as well as loss of control.
Installation Note
Noise suppression capacitors should be installed on almost all motors.
If the proper capacitors are not installed, high frequency noise will reduce range and
cause loss of control along with various other problems.
Installation Note
Inspect all linkage installations and any point where metal could come in contact with
other metal parts. Make sure these parts do not touch other metal parts under vibration.
Should a linkage or other metal parts come in contact with other metal parts under
vibration, the high frequency noise generated by this contact will cause interference
and possible loss of control.

Caution
Disassembly Prohibited
Do Not disassemble any part of this system that is not specified in the instruction
manual.
Futaba will not be responsible for any damage due to improper disassembly of any
part of the radio control system.
