Operation Precautions
Warning
Prohibited Procedures
Do not operate two or more models
on the same frequency at the same
time.
Operating two or more models at same time on the
same frequency will cause interference and loss of
control of both models.
AM, FM (PPM) and PCM are different methods
of modulation. Nonetheless the same frequency
can not be used at the same point in time, regard-
less of the signal format.
Do not operate outdoors on rainy
days , run through puddles of water or
when visibility is limited.
Should any type of moisture (water or snow) enter any
compoent of the system, erratic opreation 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 rowboats are present.
-Near high tension power lines or communi-
cation broadcasting antennas.
Interference could cause loss of control . Improper in-
stallation 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 alcohol or drugs.
Your judgment is impaired and could result in a dan-
gerous situation that may cause serious injury to
yourself as well as others.
Mandatory Procedures
Extend the transmit-
ter antenna to its full
length.
If the transmitter antenna is not
fully extended the operating
range of the radio will be re-
duced.
Check the transmitter antenna to be
sure it is not loose.
If the transmitter antenna works loose, or is discon-
nected while the model is running signal transmission
will be lost. This will cause you to lose control of the
model..
Always perform a operating range
check prior to use.
Problems with the radio control system as well as im-
proper installation in a model could cause loss of con-
trol.
(Simple range test method)
Have a friend hold the model, or clamp it down or
place it where the wheels or prop can not come in
contact with any object. Walk away and check to
see if the servos follow the movement of the con-
trols on the transmitter. Should you notice any ab-
normal operation, Do not operate the model. Also
check to be sure the model memory matches the
model in use.

Caution
Prohibited Procedures
Mandatory Procedures
Do not touch the engine, motor, speed control or any part of
the model that will generate heat while the model is operating
or immediately after its use.
These parts may be very hot and can cause serious burns.
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 en-
gine not running or the motor
disconnected.
You may unexpectedly lose control and
create a dangerous situation.
When operating your model
always display a frequency
flag on your transmitter an-
tenna.
When adjusting the transmitter on land while preparing to run (cruise), take measures
so that the wind will not knock over the transmitter.
If the transmitter is knocked over, the throttle stick may be accidentally set to the operating position and you may
lose control.
(Fail safe function) ---H.R.S or PCM mode only
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 operating direction of a servo, the fail safe function must be reset.

Nicad Battery Handling Precautions
(Only when Nicad batteries are used)
Warning
Mandatory Procedures
Always check to be sure your batter-
ies have been charged prior to oper-
ating the model.
Should the battery go dead while the model is operat-
ing loss of control will occur and create a very danger-
ous situation.
To recharge the transmitter Nicad ,
use the special charger made for this
purpose.
Overcharging could cause the Nicad battery to over-
heat, leak or explode. This may lead to fire, burns,
loss of sight and many other type's of injuries.
Caution Prohibited Items
Do not use commercial AA
size Nicad batteries.
Quick charging may cause the
battery contacts to overheat and
damage the battery holder.
Do not short circuit the Nicad battery
terminals.
Causing a short circuit across the battery terminals
may cause abnormal heating, fire and burns.
Do not drop the Nicad battery or ex-
pose 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
Nicad battery .
Should the battery be left connected this could create
a dangerous situation if someone accidentally turns
on the receiver power switch. Loss of control would
occur.
Special
Charger
Nicad AA size
batteries.
Use
prohibited
Shock
Prohibited
Never insert or remove the charger
while your hands are wet.
You may get an electric shock.
Mandatory Procedures

Storage and Disposal Precautions
Warning
Prohibited Procedures
Do not leave the radio system or
models within the reach of small chil-
dren.
A small child may accidentally operate the system,
this could cause a dangerous situation and injuries.
Nicad batteries can be very dangerous when mis-
handled and cause chemical damage.
Do not throw Nicad batteries into a
fire. Do not expose Nicad batteries to
extreme heat. Also do not disas-
semble or modify a Nicad battery
pack.
Overheating and breakage will cause the electrolyte
to leak from the cells and cause skin burns, loss of
sight as well as other injuries.
Mandatory Procedures
When the system will not be used for
any length of time store the system
with 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 nicad bat-
tery may considerably reduce the capacity . A reduc-
tion in operating time will occur even when the batter-
ies are charged for the recommended time.
<Nicad Battery Electrolyte>
The electrolyte in Nicad batteries is a strong alkali. Should you get even the
smallest amount of the electrolyte in your eyes, DO NOT RUB, wash immedi-
ately with water, seek medical attention at once. The electrolyte can cause blind-
ness. If electrolyte comes in contact with your skin or clothes, wash with water
immediately.
Caution
Prohibited Procedures
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 opreation.
Mandatory Procedure
If the system will not be used for a
long period of time remove the batter-
ies 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.
<Nicad Battery Recycling>

the use of other than Futaba genuine parts. Use the
parts specified in the instruction manual and catalog.
Mandatory Procedures
Caution
Prohibited Procedures
Never use any RF module other than the RF module specially designed for the 3VCS.
Futaba will not be responsible for any problems caused by the use of non-Futaba parts or equipment in conjunc-
tion with this radio system. Please use parts and equipment that are listed in this instruction manual alone. There
is no compatibility between module TZ-FM module for T3VCS and TU-FM module for T3VC. Even if those mod-
ules were used mistakenly, the performance would be very poor and the control area would become narrow,
causing out-of-control.

12
Before Using
- High Response System (H.R.S. system)
When used with the H.R.S. system, a speed of triple that of an FM system at average
response is realized. (Comparison with other Futaba products) The T3VCS transmit-
ter is compatible with the H.R.S. system, PCM1024 system, and PPM (FM) system.
- 110x64 dot large graphic LCD/with backlighting
EXP curve, throttle curve, servo view, and other graph display and function selection
can batch display simple menus and function setup items, and data setup is easy.
Backlighting that can be turned ON/OFF also improves recognition at indoor cir-
cuits,
etc.
- 10 models memory/+ 10 models by using a data pack
Model names can use up to 10 letters, numbers, and symbols so that easily under-
stood
names can be set. Model copy function simplifies creation of a model memory with
different fine setups. An additional 10 models memory can be added by using the
optional CAMPac-16K.
- Two function selection modes: Menu selection and direct call
Setup screens are called from a menu screen. The menu screen can be selected from
among 3 levels (LV1/LV2/LV3) to match the level of use.
Frequently used (high urgency) functions can be quickly called by assigning them to
direct call buttons. (6 functions)
- Brake mixing for large cars (BRAKE-MIX)
Brake mixing of the front and rear wheels of 1/5GP cars, etc. has delay and balance
adjustment functions.
- Second dual rate (2ND D/R)
Steering angle can be switched with one touch while running.
- Anti-skid Braking System (A.B.S.)
This function applies the brakes so that the tires of gasoline engine cars, etc. do not
lose their grip on the road even when braking at corners.
- Throttle acceleration (TH-ACCEL)
Gasoline engine cars have a time lag before the clutch and brakes are connected. The
TH-ACCEL function minimizes this time lag.
- Throttle speed (TH-SPEED)
Sudden trigger operation on slippery roads only spins the wheels unreasonably and
does not accelerate smoothly. Setup the throttle speed function allows smooth and
enjoyable operation while at the same time reducing battery consumption.
