Under other conditions, the set will not operate, or the specified performance will not be displayed even if it operates. In addition, it may cause servo trouble. Futaba will not be responsible for damage, etc. caused by combination with the prod- ucts of other companies.
Page 8: Operation Precautions
Operation Precautions Warning Do not operate outdoors on rainy days, run through puddles of water or use when visibility is lim- ited. Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control may oc- cur.
Page 9: Battery Handling Precautions
If the power is cut off while run- ning (cruising), a collision may occur. The use of Futaba a genuine NiMH or LiFe battery pack is strongly recommended.
Page 10: Storage And Disposal Precautions
Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed con- trols), Ni-MH/Ni-Cd/Li-ion batteries and other optional accessories. Futaba will not be responsible for problems caused by the use of other than Futaba genuine parts. Use the parts speci- fied in the instruction manual and catalog.

Page 31: Installation
Installation Receiver And Servo Connections Connect the receiver and servos as shown below. Connect and install the receiver and ser- vos in accordance with "Installation Safety Precautions" on the next page. The figure shown below is an example. The method of connecting the motor controller to the motor and battery depends on the motor controller used.
Page 32: Installation Safety Precautions
Installation Safety Precautions Warning Receiver (receiver antenna) Do not cut or bundle the receiver antenna wire. Do not bundle the receiver antenna wire together with the motor controller lead wire. Keep the receiver antenna wire at least 1cm away from motor, battery, and other wiring carrying heavy current. Do not use a metal receiver antenna holder on a plate made of metal, carbon, or other conductive material.
Page 33 Warning Connector Connections Be sure the receiver, servo, battery and connectors are fully and firmly connected. If vibration from the model causes a connector to work loose while the model is in operation, you may lose control . Servo Installation When you install the servos, always use the rubber grommets provided in servo hardware bags.
Page 34 Warning Electronic Speed Cont Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other parts that conduct electricity. If the FET Amp (Electronic speed control) heat sinks touch other materials that conduct electricity a short circuit could oc- cur.
Page 35: Initial Set-Up
*When the "PWR" side power switch is set to ON and radio waves are output normally, "T-FHSS", "S-FHSS", or "FASST" is displayed. If not displayed, there is probably an abnormality or trouble so contact a Futaba Service Center. When a screen is displayed at the "DSP" side, "Display" is dis- played.
Page 36: Receiver Type Change & How To Link
Receiver Type Change & How To Link First set up the receiver. Setting changes are immediately reflected. Next, the transmitter and receiver are linked and the receiver memorizes the transmitter ID number so that sig- nals from other transmitters will not be received. In addition, with the T-FHSS telemetry system, the transmitter simultaneously memorizes the receiver ID numbers so that data from other re-...
Page 37 Bring the transmitter and receiver within 50cm of each other (antennas do not touch) and turn on the receiver power. Move the cursor to "Link" by T4PX transmitter (JOG) button up or down operation. When the (JOG) button is pressed, a chime will sound and the T4PX will enter the link mode for 20 seconds.
Page 38: Receivers Other Than T-Fhss
Precaution: If there are many Futaba 2.4GHz systems (T-FHSS/ S-FHSS/ FHSS) turned on in close proximity to your receiver might not link to your transmitter. In this case, even if the receiver’s LED stays solid green, unfortunately the re- ceiver might have established a link to one of other transmitters.

If the value is larger than the standard value, the brake is applied before the stop position. Especially, when a large load is applied, overshoot, etc.
Page 129: Telemetry System
Telemetry System With the telemetry system, the running status can be displayed at the transmitter and also recorded as a data log by installing various sensor units to the chassis (The S-FHSS and FASST systems do not have a telemetry function.) -The sensor data can be checked at the transmitter by connecting the telemetry sensor sold separately to the S.BUS2 connector of the R304SB receiver.
Page 130: Telemetry Menu
Telemetry Menu It is necessary to turn on the telemetry on the receiver setting screen to use the telemetry func- tion. (p.46) This screen displays and sets the various information from the receiver. An alarm and vibra- tion can be generated depending on the information. The alarm and the vibration are set by each information screen.

Page 133: Telemetry :Rpm
Telemetry :RPM Speed information from an SBS-01RM (telemetry rotation sensor) sold separately is dis- played and set at this screen. The speed of the engine, motor, etc. of the chassis while run- ning can be viewed at the transmitter. When the speed becomes higher (lower) than the set speed, it can be announced by an alarm and vibration.
Page 134: Telemetry :Temperature
Telemetry :Temperature This screen displays and sets the temperature information from an SBS-01T (telemetry temperature sensor) sold separately. The temperature of the engine, motor, amp, etc. of the chassis while running can be viewed at the transmitter. When the temperature becomes higher (lower) than the set value, it can be announced by an alarm and vibration.
Page 135: Sensor Menu
Sensor Menu This menu registers the telemetry sensors used with the transmitter. When only one of a certain type of sensor is used, this setting is unnecessary and the sensor can be used by simply connect- ing it to the S.BUS2 port of the transmitter. When using 2 or more of the same kind of sensor, they must be registered here.
Page 136: Sensor Reload
When sensor registration or slot number change was performed and the message " Failed. The connected sen- sor is not ready. " was displayed, check the sensor con- nection.
