For Your Safety As Well As That Of Others
Warning
Do not operate outdoors on rainy days, run through puddles of water or use when visibility is limited.
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.
-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 in-
jury.
Do not operate this R/C system 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 as well as others.
Do not touch the engine, motor, speed control or any part of the model that will generate heat while the mod-
el 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.
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.
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 disconnected.
You may unexpectedly lose control and create a dangerous situation.
Before running (cruising), check the fail-safe function.
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 operat-
ing direction of a servo, the fail-safe function must be reset.
Setting example: Throttle idle or brake position
Operation Precautions

Warning
Never plug the charger into an outlet of other than the indicated voltage.
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.
You may get an electric shock.
Do not use the T4PM transmitter’s battery as the receiver’s battery.
Since the transmitter’s battery has an overload protection circuit, the output power will be shut down when the high current load is ap-
plied. This may result in runaway or fatal crash.
Always check to be sure your batteries have been charged prior to operating the model.
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.
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.
Caution
Do not use commercial AA size NiCd and NiMH batteries.
Quick charging may cause the battery contacts to overheat and damage the battery holder.
Do not short circuit the battery terminals.
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.
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.
Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power switch. Loss of
control could occur.
Always keep the charger disconnected from the outlet while it is not in use.

For Your Safety As Well As That Of Others
(Only when NiMH / NiCd / LiFe batteries are used)
NiMH / NiCd / LiFe Battery Handling Precautions
Storage And Disposal Precautions
Warning
Do not leave the radio system or models within the reach of small children.
A small child may accidentally operate the system. This could cause a dangerous situation and injuries. NiCd batteries can be very
dangerous when mishandled and cause chemical damage.
Do not throw NiMH / NiCd / LiFe batteries into a fire. Do not expose batteries to extreme heat. Also do 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 NiMH / NiCd batteries 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 NiMH / NiCd battery may consider-
ably 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)
When a LiFe battery pack will not be used for a long time, to prevent it from deteriorating we recommend
that it be kept in about the half capacity state instead of fully charged. Also be careful that the battery does
not enter the over-discharged state due to self-discharge.
Periodically (about every 3 months) charge the battery.
Warning
Do not store your R/C system in the following places.
- 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 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.
10
For Your Safety As Well As That Of Others
<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.
Caution
Do not expose plastic parts to fuel, motor spray, waste oil or exhaust.
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 controls), NiMH/
NiCd / LiFe 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 in-
struction manual and catalog.
Other Precautions
<NiMH / NiCd / LiFe 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.

Before Using
-T-FHSS SR (Super response) & telemetry T-FHSS
In addition to the T- FHSS telemetry system, we added a T-FHSS SR (Super response) system
that increased processing speed to further improve response. (SR system does not support telem-
etry function)
*R304SB and R304SB-E are not compatible with SR system.
-T-FHSS MINIZ system
By setting to the MINIZ system in the receiver setting menu, you can use Kyosho Mini - Z Evo
dedicated receiver RA-42. Dedicated receiver RA-42 requires purchase separately.
-Telemetry system
The T4PM transmitter has adopted the newly developed bidirectional communication system "T-
FHSS".
-2.4GHzSS (Spread Spectrum) radio communication system
Frequency channel setting is unnecessary: Channel shifting takes place within the 2.4GHz band
automatically. This system minimizes the interference from other 2.4GHz systems.
-Display switch
Display switch allows function setup without transmitting.
-Model memory for 40 models
Model names can use up to 10 letters, numbers, and symbols, so that logical names may be used.
A model memory with different setups can be created by using the model copy function.
-4 axis Jog button.
The (JOG) button can be operated in 4 directions: up, down, left, and right.
-ESC-Link function (MC-LINK)
This dedicated function allows you set up the Link software so that your T4PM can control vari-
able frequency and other data changes in Futaba speed controllers (ESCs): MC950CR, MC850C,
MC851C, MC602C, MC402CR, etc.
-S.BUS servo
This is a special function that allows setting of the parameters of our S.BUS servo whose set-
tings are changed by using PC Link software. In addition to the conventional wired system, it
can be set wirelessly in combination with the R334SBS or R334SBS-E.
-Steering mixing
Smooth cornering is possible by independent left and right steering servo setting.
-Brake mixing for large cars (BRAKE)
Brake mixing of the front and rear wheels of 1/5 gas power cars and other large cars can be ad-
justed independently.
Before Using
Features

12
Before Using
-Gyro mixing (GYRO MIX)
The sensitivity of Futaba car rate gyros can be adjusted from the T4PM.
-4WS mixing for crawlers and other 4WS type (4WS)
This function can be used with crawlers and other 4WS type vehicles.
-Dual ESCs mixing for crawlers cars (DUAL ESC)
ESCs at the front and rear are controlled independently.
-CPS-1 mixing (CPS MIX)
LED lighting and ashing control using our CPS-1 channel power switch can be matched to
steering and throttle operation by switch only.
-Anti-skid braking system (TH A.B.S)
This function applies the brakes so that the tires of gas power cars, etc. do not lose their grip on
the road even when braking at corners.
-Throttle acceleration (ACCEL)
gas power cars have a time lag before the clutch and brakes become effective.
The throttle acceleration function reduces this time lag.
-Throttle speed (SPEED)
Sudden trigger operation on a slippery road surface will only cause the tires to spin and the
model to not accelerate smoothly. By setting the throttle speed function, operation can be per-
formed smoothly and easily. It also suppresses battery consumption.
-Steering speed (SPEED)
When you sense that the steering servo is too fast, etc., the servo operating speed (direction that
suppresses the maximum speed) can be adjusted.
-Racing timer (TIMER)
The lap timer can record 100 lap times and total time. The timer can also be started automati-
cally by trigger operation. The race time and audible alarm can be set.
Re-/fueling time are indicated by an audible alarm. An up timer is also provided.
-Function select switch (SWITCH)/ dial function (TRIM DIAL)
This assigns functions to 2 switches and dials (digital trim, digital dial). The step amount and
operating direction can also be adjusted. Trim positioning at each model call is unnecessary
because all the dials are digital.
-Trigger position can be changed
The position of the throttle trigger can be moved forward and backward.
-Tension adjustment function
The tension of the steering wheel & throttle trigger springs can be adjusted from the outside.
-Mechanical ATL Adjustment
Make this adjustment when you want to decrease the total travel of the brake (push) side of the
throttle trigger.

hours, the FT2F1700BV2 battery is 2.5 hours, the FT2F1700BV2 battery is 2 hours. When the LiFe battery will not
be used for a long time, to prevent it from deteriorating we recommend that it be kept in about the half capacity state
instead of fully charged. Also be careful that the battery does not enter the overdischarged state due to self discharge.
Periodically (about every 3 months) charge the battery. In addition, always remove the battery from the model and
store it in a dry, cool place (15°C~25°C).
With Balance Charger
(Example: When using the
FT2F100B / 1700BV2 / 2100BV2
with an optional charger)
LiFe battery is removed from the
transmitter.
1Remove the battery cover.
2Disconnect the battery from the T4PM.
3Balance charging cannot be done through the
transmitter. You must remove the LiFe bat-
tery to do this charge.
Follow the directions of the optional LiFe chargers in use.

Warning
Make sure not to peel off the battery film, or make any scratch by a cutter knife or the sharp edges of metal
components.
Make sure not to soak or get the battery wet with water or seawater.
Make sure not to use a deformed or swollen battery.
There is a risk of explosion or fire, which is very dangerous.
Caution on charger
Warning
The charger 9M20A05401 (FUTM 1725) does not charge batteries other than FT2F1100B / FT2F1700B V2 /
FT2F2100B V2.
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.
Never plug it into an outlet having other than the indicated voltage.
Plugging the charger into the wrong outlet could result in an explosion or fire.
Do not insert and remove the charger when your hands are wet.
It may cause an electric shock.
Always use the special charger or a quick charger for digital proportional R/C sets to charge a digital propor-
tional R/C set battery.
Overcharging a NiMH battery can result in burns, fire, injuries, or loss of sight due to overheating, breakage, or electrolyte leakage.
Caution
Do not plug the charger to the charging jack, if the battery is not connected to the transmitter.
The transmitter may be damaged.
When the charger is not in use, disconnect it from the AC outlet.
Do this to prevent accidents and to avoid overheating.

Before Using
Steering And Throttle Trim Operation
Digital Trim Operation
(Initial settings: DT1: Steering trim, DT2: Throttle trim, DT3: Channel 3, DT4: Steering D/R, DT5: ATL-Brake rate)
Operating by the trim: Push the trim lever to the left or right (up or down). The current
position is displayed on the LCD screen.
• Each step is indicated by a tone.
• When the trim exceeds the maximum trim adjustment range, the
beep will change and the servo will not move any farther.
• Steering D/R: The steering left and right servo travels are ad-
justed simultaneously.
• ATL: Decreases the set value when the braking effect is strong
and increases the set value when the braking effect is weak.
With the center trim feature, trim adjustments have no
effect on the maximum servo travel. This prevents the
linkages from binding when adjustments are made.
Adjustment
1Using a 1.5 mm hex wrench, adjust the trigger
brake (reverse) stroke. (The screw moves the
throttle trigger stopper.)
• When the screw is turned clockwise, the stroke becomes narrow-
er. Adjust the stroke while watching the screw.
Note:
Mechanical ATL Adjustment
Make this adjustment when you want to decrease the stroke of the brake (back) side of
the throttle trigger to your preferences.
Once you have changed the mechanical stroke on the brake side, be sure to adjust
the scale of the throttle channel accordingly by using the "Adjuster Function" (page
71).
Due to this change, you also need to adjust in most cases the travel of the throttle
servo by using "End Point Adjuster".
