Operation Precautions

Warning

ｎ

Do not operate outdoors on rainy days, run through puddles of water or use when visibility is limited.

ｌ

Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control
may occur.

Do not operate in the following places.

ｌ

-Near other sites where other radio control activity may occur.

-Near people or roads.

-On any pond when passenger boats are present.

-Near high tension power lines or communication broadcasting antennas.

Interference could cause loss of control. Improper installation of your Radio Control System in your model could result in
serious injury.

Do not operate this R/C system when you are tired, not feeling well or under the influence of

ｌ

alcohol or drugs.

Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself as well as
others.

Do not touch the engine, motor, speed control or any part of the model that will generate heat

ｌ

while the model is operating or immediately after its use.

These parts may be very hot and can cause serious burns.

Always perform an operating range check prior to use.

ｊ

Problems with the radio control system as well as improper installation in a model could cause loss of control.

(Simple range test method)
Have a friend hold the model, or clamp it down or place it where the wheels or prop cannot come in contact with
any object. Walk away and check to see if the servos follow the movement of the controls on the transmitter. Should
you notice any abnormal operation, do not operate the model. Also check to be sure the model memory matches the
model in use.

Turning on the power switches.

ｊ

Always check the throttle trigger on the transmitter to be sure it is at the neutral position.

1. Turn on the transmitter power switch.

2. Turn on the receiver or speed control power switch.

Turning off the power switches
Always be sure the engine is not running or the motor is stopped.

1. Turn off the receiver or speed control power switch.

2. Then turn off the transmitter power switch.

If the power switches are turned off in the opposite order, the model may unexpectedly run out of control and cause a
very dangerous situation.

When making adjustments to the model, do so with the engine not running or the motor discon-

ｊ

nected.

You may unexpectedly lose control and create a dangerous situation.

For Your Safety As Well As That Of Others

ｎ

Caution

(Fail safe function)

Before running (cruising), check the fail safe function.

ｊ

Check Method; Before starting the engine, check the fail safe function as follows:

1) Turn on the transmitter and receiver power switches.

2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail
safe data to the receiver every minute.)

3) Check if the fail safe function moves the servos to the preset position when reception fails.

The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when
reception fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was
used to change the operating direction of a servo, the fail safe function must be reset.
Setting example: Throttle idle or brake position

NiMH / NiCd Battery Handling Precautions

(Only when NiMH/NiCd batteries are used)

Warning

ｎ

Never plug the charger into an outlet of other than the indicated voltage.

ｌ

Plugging the charger into the wrong outlet could result in an explosion or fire.

Never insert or remove the charger while your hands are wet.

ｌ

You may get an electric shock.

Do not use the transmitter's battery, HT5F1700B, as the receiver's battery.

ｌ

Since the transmitter's battery has an overload protection circuit, the output power will be shut down when the high cur­rent load is applied. This may result in runaway or fatal crash.

Always check to be sure your batteries have been charged prior to operating the model.

ｊ

Should the battery go dead while the model is operating, loss of control will occur and create a very dangerous situation.

To recharge the transmitter battery, use the special charger made for this purpose.

ｊ

Overcharging could cause the battery to overheat, leak or explode. This may lead to fire, burns, loss of sight and many
other types of injuries.

ｎ

Caution

Do not use commercial AA size NiCd and NiMH batteries.

ｌ

Quick charging may cause the battery contacts to overheat and damage the battery holder.

Do not short circuit the battery terminals.

ｌ

A short circuit across the battery terminals may cause abnormal heating, fire and burns.

Do not drop the battery or expose it to strong shocks or vibrations.

ｌ

The battery may short circuit and overheat; electrolyte may leak out and cause burns or chemical damage.

When the model is not being used, always remove or disconnect the battery.

ｊ

Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power
switch. Loss of control could occur.

10

Always keep the charger disconnected from the outlet while it is not in use.

ｊ

Storage and Disposal Precautions

Warning

ｎ

Do not leave the radio system or models within the reach of small children.

ｌ

A small child may accidentally operate the system. This could cause a dangerous situation and injuries. Ni-Cd batteries
can be very dangerous when mishandled and cause chemical damage.

Do not throw NiMH/NiCd batteries into a fire. Do not expose batteries to extreme heat. Also do

ｌ

not disassemble or modify a battery pack.

Overheating and breakage will cause the electrolyte to leak from the cells and cause skin burns, loss of sight, and other
injuries.

When the system will not be used for any length of time, store the system with HT5F1700B batter-

ｊ

ies in a discharged state. Be sure to recharge the batteries prior to the next time the system is used.

If the batteries are repeatedly recharged in a slightly discharged state, the memory effect of the Ni-MH/Ni-Cd battery
may considerably reduce the capacity . A reduction in operating time will occur even when the batteries are charged for
the recommended time. (After discharge to 1cell E.V.=1V)

<NiMH/NiCd Battery Electrolyte>

The electrolyte in NiCd/NiMH 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.

Warning

ｎ

Do not store your R/C system in the following places.

ｌ

- Where it is extremely hot or cold.

- Where the system will be exposed to direct sunlight.

- Where the humidity is high.

- Where vibration is prevalent.

- Where dust is prevalent.

- Where the system would be exposed to steam and condensation.

Storing your R/C system under adverse conditions could cause deforma­tion and numerous problems with operation.

If the system will not be used

ｊ

for a long period of time, re­move the batteries from the
transmitter and model and
store in a cool, dry place.

If the batteries are left in the trans­mitter, electrolyte may leak and dam­age the transmitter. This applies to
the model also. Remove the batteries
from it also to prevent damage.

<NiMH/NiCd/Li-ion Battery Recycling>

A used battery is a valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center.

Other Precautions

ｎ

Caution

Do not expose plastic parts to fuel, motor spray, waste oil or exhaust.

ｌ

The fuel, motor spray, waste oil and exhaust will penetrate and damage the plastic.

Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed con-

ｊ

trols), NiMH/NiCd batteries and other optional accessories.

Futaba will not be responsible for problems caused by the use of other than genuine Futaba parts. Use the parts speci­fied in the instruction manual and catalog.

How to link the transmitter and the receiver

Each transmitter has an individually assigned, unique ID code. In order to start opera­tion, the receiver must be linked with the ID code of the transmitter to which it is being
paired. Once the link is made, the ID code is stored in the receiver and no further link­ing is necessary unless the receiver needs to be used with another transmitter.

Link procedure

1

Bring the transmitter and the receiver close to each other,

within 20 inches (half meter).

2

Turn on the transmitter.

3

Turn on the receiver.

Before Using

4

Push the tactile switch of the receiver.

When the link is complete, the LED in the receiver changes
to solid green.

Precaution:

If there are many Futaba S-FHSS/FHSS systems turned on in close proximity to the R2104GF, your
receiver might not link to your transmitter. In this case, even if the receiver's LED stays solid green, un-

fortunately the receiver might have established a link to one of other transmitters. This is very dangerous
if you do not notice this situation. In order to avoid the problem, we strongly recommend you to double­check whether your receiver is really under control by your transmitter by giving the stick input and then
checking the servo response.

*Please refer to the table below for LED status vs receiver's condition.

LED status vs receiver's condition:

No signal reception Red : On
Receiving signals Green: On
Receiving signals, but ID is unmatched. Green: Blink

*1: LED could be change to red during intermittently during data processing.

ｎ

Warning

After the linking is done, please cycle receiver power and check if the receiver to be linked is re-

ｊ

ally under the control of your transmitter.

Do not perform the linking procedure with motor’s main wire connected or the engine operating

ｌ

as it may result in serious injury.

Transmitter mode setting

Set the transmitter to the "HIGH" mode or "NORM" mode. See page 42 for a description of the

setting method.

However, digital servos (including BLS Series brushless servo) can only be used in the HIGH mode.

Note:

When the power is turned on, whether the receiver is in the "HIGH" or "NORM" mode the R2104GF operates in that mode until
the power is turned off. When the transmitter mode is changed, operation becomes possible when the receiver power is turned on
again.

Installation

Receiver and Servo Connections

Connect the receiver and servos as shown below. Connect and install the receiver and
servos 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. Purchase the motor con­troller and servos separately. The receiver also depends on the set.

ｎ

Receiver (receiver antenna)

Do not cut or bundle the receiver antenna wire.

ｌ

Do not bundle the receiver antenna wire together with the motor controller lead wire.

ｌ

Keep the receiver antenna wire at least 1cm away from motor, battery, and other wiring carrying heavy current.

ｌ

Install the receiver antenna holder as closely as possible to the receiver.

ｊ

If the antenna wire is cut, bundled, or routed near a noise source, the receiving sensitivity will drop, the running (sailing)
range will decrease, and you may lose control of the model.

*Noise is transmitted through metal, carbon, and other conductive material, so keep the receiver antenna wire away from such parts.

Antenna

Battery

Install the receiver as far away as possible from the
battery, motor controller, motor, silicon cord and
other noise sources. Keep it away from the antenna
wire, in particular.

Receiver vibration-proofing / waterproofing

(Car)

Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material

ｊ

and mount it with thick double-sided tape.

When using the receiver holder supplied with the model kit, mount the holder to the chassis

ｊ

through a rubber grommet.

(Boat)

Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material.

ｊ

Also waterproof the receiver by sealing it in a plastic bag.

If the receiver is exposed to strong vibration and shock, it will operate erroneously due to the invasion of water drops

and you may lose control of the model.

Foam rubber, etc.

Screw

Mechanical plate

Wrap the receiver in foam rubber or other
vibration-absorbing material. Do not use
hard material. Hard material does not
have a vibration-proofing effect.

Warning

ｎ

Connector Connections

Be sure the receiver, servo, battery and connectors are fully and firmly connected.

ｊ

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.

ｊ

Mount the servos so they do not directly come in contact with the mount.

If the servo case comes in direct contact with the mount, vibration will be directly transmitted to the servo.

If this condition continues for a long time, the servo may be damaged and control will be lost.

Electronic Speed Control

Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other

ｊ

parts that conduct electricity.

If the FET Amp (Electronic speed control) heat sinks touch other materials that conduct electricity a short circuit could
occur. This could result in loss of control and damage to the system.

Motor Noise Suppression

Always install capacitors to suppress noise when electric motors are used.

ｊ

If capacitors are not properly installed you could experience erratic operation and reduced range as well as loss of con­trol.

your motor.
The Schottky diode improves the efficiency of the
speed control / motor combination and provides
extra protection to the brake FETs. The white ring
must always face the positive side.

Other Noise Suppression Methods

Be sure there are no metal parts in your model which under vibration can come in contact with

ｊ

other metal parts.

Metal to metal contacts under vibration will emit a high frequency noise that will affect the receiver's performance. You
could experience erratic operation and reduced range as well as loss of control.

Receiver Mode "RX MODE"

The T4PL transmitter has an FHSS 2.4GHz system transmit mode and an in­creased response S-FHSS 2.4GHz system transmit mode. The R2104GF supplied
with the T4PL set can be used by both the S-FHSS (SFH) and FHSS(FH) type
by automatic recognition. However, when the FHSS 2.4GHZ system R603GF/
R2004GF is used, operation is impossible if it is not the FHSS(FH) type.

When the setting is incorrect, change it by "TYPE". Which RX type is set can be
checked with the HOME screen.

Servos used

When the RX type is S-FHSS(SFH), the servo response can be selected from high
speed (HIGH) and normal (NORM) mode. The high speed mode is exclusively
for our digital servos (including BLS system brushless servo). When using other
servos, select the normal mode. All servos, including digital servos, can be used in
the normal mode. When the RX type is FHSS(FH), the high speed (HIGH) mode
cannot be used.

down side operation amount adjustment during linkage.

- Correct the maximum steering angle for left and right steering angles when there
is a difference in the turning radius due to the characteristics, etc. of the vehicle.

Maximum steering angle

The EPA function basically determines the maximum steering angle of each channel.

The functions shown below may have been adjusted or the operating range set by EPA
function may be exceeded. Check the linkage each time the following functions are
adjusted.

- Sub trim (all channels) .................................. P45

- Program mixing slave side (all channels) .....P66

- Idle up (throttle) ............................................ P79

- Throttle dff, Engine Cut (throttle)................. P81

- Throttle acceration (throttle) ......................... P57

ATL trim

ATL trim allows adjustment of the brake side operation amount during operation.
Therefore, when the operating angle is adjusted with throttle EPA, ATL trim must also
be taken into account.

Warning

ｎ

Operate each servo over its full stroke and be sure

ｊ

the linkage does not bind or is not loose.

Function

The continuous application of unreasonable force to a servo may
cause damage and excessive battery drain.

Adjust the steering servo so that unreasonable force
is not applied to the servo by the chassis at maxi­mum servo travel.

Adjust the throttle servo so that unreasonable force is not applied when the engine carburetor is
fully open, fully closed, and the brakes are applied fully.
If the brakes overheat while running, their ability to function properly decreases. Before running,
adjust the suitable maximum servo travel so that unreasonable force is not applied even when the
servo travel is increased while running.

Caution!

A howling noise indicates

that the steering servo is

improperly set.

Decide the EPA value
at the contact point.

Fail Safe/Battery Fail Safe Function "F/S"

Fail Safe Mode (F/S)

(All channel)

This function moves each servo to a preset position when the receiver cannot receive the
signals from the transmitter for some reason.

-When the condition set at "FH" is Rx type (P42), fail safe (F/S) can be set only for throttle (TH). Other channels are set to
the normal mode.

-The fail safe data is transferred from the transmitter to the receiver 10 seconds after the transmitter power was turned on.
The data is transferred every 5 seconds after that. Be careful because normally the transmitter power is turned on first and the
receiver power is turned on next and the data is transferred for approximately 10 seconds after the receiver power is turned
on.

-For gasoline engine cars, for safety we recommend that this fail safe function be used to set the throttle channel in the direc­tion in which the brakes are applied.

Hold mode (HOLD)

This function holds the receiver in its position immediately before reception was lost. It
is an R2104GF and other S-FHSS type receiver only function. When the receiver used
is the R603GF/R2004GF FHSS type, this function cannot be used because the receiver
type is set to "FH" by receiver type setting (p.42).

Off mode (OFF)

This function stops output of signals to the servos and places the servos into the free
state when the receiver cannot receive.

The F/S, HOLD, and OFF modes are automatically reset when signals from the trans­mitter can be received again.

Battery fail safe function (BFS)

If the receiver battery voltage drops below a certain value when this function is enabled,
the throttle servo moves to the position set by fail safe function. When the battery volt­age recovers, the battery fail safe function is automatically reset.

-This function cannot be used when the throttle (TH) is not set to fail safe (F/S).

-This function is for the R2104FG and other S-FHSS types only. It cannot be used with the R603GF and R2004FG FHSS
type.

Throttle Speed "SPEED"

Throttle Acceleration "ACCFW / ACCBK"

(Throttle system)

The servo will jump to the input position at its maximum possible speed. Unlike expo­nential, which adjusts the whole throttle movement into a curve, throttle acceleration
simply "jumps" away from neutral and then leaves the remaining response linear.

Operation

- Operation near the throt­tle trigger neutral position
becomes a sharp rise.

- The forward and brake

BRAKE

The standard value (100% point) of this setup affects the operation amount set by
throttle EPA function.

Convenient usage method

For gasoline engine cars, the linkage must have a

Clearance

clearance because one servo controls the engine
carburetor and brake. Thus, there is a noticeable
time delay at both the forward and brake sides.
Sharp response comparable to that of electric mo-

Caburetor

Servo horn

tor cars is obtained by reducing this clearance at
the transmitter side.

Fail Safe Unit

When the T4PL is used with the Futaba fail safe unit (FSU-1), it will operate as de­scribed below. However, FSU-1 cannot be used at the high speed mode.

- When the FSU-1 is connected to the throttle channel, and the A.B.S. function has
been activated, the FSU-1 LED will flash each time the servo operates. The reason
for this is that the FSU-1 responds to sudden data changes caused by A.B.S. function
pumping operation. It does not mean that the fail safe function is activated. The servo
will not be affected.

Idle-Up "IDLUP"

This is a function select switch function. The idle up ON/OFF switch must be set. (P62)

This function is used to improve engine starting performance by raising the idling speed
when starting the engine of a gasoline car (boat). It is also effective when you want to
prevent the braking when the power was turned off during running, due to the effect
of your gear ratio setting and choice of motor when operating an electric car. However,
considering safety, and to prevent the motor from rotating instantly when the power was
turned on, the MC950CR, MC851C, MC602C, MC402CR, and other Futaba MC (Motor
Controllers) will not enter the operation mode if the neutral position is not confirmed.
When using the MC950CR, MC851C, MC602C, MC402CR, or other Futaba MC, con­firm that the MC is in the neutral position and the set is in the operation mode before
setting the idle up function switch to ON.

Operation

The throttle neutral position is offset to the forward side or brake side. There is no link­age locking, etc. because there is no change near the maximum operation angle even
when the neutral position is offset by this function.

This is a special function which lets you set the contents of the Link software
which performs Futaba speed controller (ESC), MC950CR, MC851C, MC602C,
MC402CR, etc. variable frequency and other data changes at the T4PL transmit­ter. However, some data changes require a PC and Link software. This function is
used by connecting ESC directly to the transmitter. The T4PL power switch is used
at the display side. Use the various optional servo extension cords according to the
distance between the transmitter and ESC. The last data read from ESC to T4PL or
the last data written from T4PL to ESC is saved to the T4PL. Since the data for each
model memory can be saved, the data of up to 40 models can be saved.

-When the T4PL battery voltage drops, the display switches to low battery display. Therefore, use this function when there is
ample battery capacity remaining.

-Also connect the battery at the ESC side.

Function

Make this setting when you want to use the brakes at the neutral throttle (OFF) position by throttle operation. The
larger this value, the greater the braking force. When you want to use the neutral brake, set this value to "0%".

CLM-(CURRENT LIMIT) 50A~300A (MC950CR:50A~300A), OFF Same as Link software Current Limiter.

Current Limiter sets the current value at maximum load here.
Since setting of the MAX is based on the output current limit value set by Current Limiter, Current Limiter does not

have to be turned OFF except when a current exceeding 300A is generated.

"MIn" which sets the frequency when the load is small, is set to the high frequency side (large value) when extension is desired after straight­aways and curves.

"MAX" which sets the frequency when the load is large, is set to the high frequency side (large value) when you want to suppress the rise
from low speed and when motor heating and commutator roughness are sensed.

When the rise from low speed is poor, and becomes bad even when "MAX" is set to the low frequency side, use the log data to check if there
was a momentary voltage drop. When you want to suppress the overall power, lengthen the run time, and otherwise improve efficiency, set

both "MAX" and "MIn" to the high frequency side. When you want to set a fixed PWM frequency at full range regardless of the load current,
set PWM frequency (at Max. load) and PWM frequency (at Min. load) to the same value.

2.5V~7.5V for MC950CR

Same as Link software Low Bat Protection
This setting cuts off the output to the motor when the

running battery voltage drops to the set voltage to
prevent the receiver from stopping operation when
the supply of voltage to the receiver becomes in suf­ficient while running due to a drop in the power sup­ply voltage. When the power supply voltage recovers,
power is supplied to the motor once more.

CTM-(C.L. TIME LIMIT) 50A~300A /CLT-(C.L. TIMER) 0sec(OFF)~240sec

(except MC950CR)

Same as Link software Current Limiter (Time Limit)/Current Limit timer.
The output current can be limited up to the set time lapse from the start of run-

ning. This is effective in preventing the motor from outputting wasted energy
when the voltage is high immediately after the power battery was recharged.

- "CTM" (Time Limit) sets the maximum output current within the time the out­put current is limited.

- "CLT" sets the time the output current is limited. This function is disabled
when set to "0" sec.

Since the Current Limit Timer starts when the throttle is operated to the for­ward side and current is output to the motor, this function begins to operate
when the motor is run during trim adjustment, etc.

FWB-(FORWARD BOOST) 0~100 (except MC850C)

Same as Link software Forward Boost
Operation near the throttle trigger (stick) neu-

tral position becomes a sharp rise.

DBA-(DEAD BAND) ±2μs~±50μs

This sets the range (neutral point range) over which the

ESC does not respond to transmitter throttle operation.
The larger the set value, the wider this range.

to "0%", the brakes are not effective.

RMD-(REVERSE MAX DUTY) w/back only 0%~100%

Same as Link software Reverse Max. Duty
This setting can set the reverse power between the neutral point and Max

REV-(REV CANCEL) BRk /REV Same as Link software Reverse Cancel.

When set to BRk, reverse operation is not performed.
LA-(LEAD ANGLE) 0~1500 Same as Link software Lead Angle.

The lead angle of the motor can be set at the MC950CR side. However, we recommend that it
normally be set to "0". Since this setting is premised on setting by referring to the speed log by
the Link software, independent use of the MC LINK function of the T4PKS is recommended.

Power supply and low battery alarm

The T4PL can use an optional rechargeable battery. However, the battery alarm setting
is different from that of the dry cell battery (alkaline battery recommended). Therefore,
always set the battery type to match the power source used. Always set the battery type
to "N5/L2" especially when using a Futaba rechargeable type battery. If the set is used
at "DRY4" setting, the time from low battery alarm to system stopping will become ex­tremely short. (See page 93, for a detailed description of the battery types.)
