Battery Recycling (for U.S.A.)
The RBRCTM SEAL on the (easily removable) nickel-cadmium battery contained in Futaba products indicates that Futaba Corporation of America is voluntarily participating
in an industry program to collect and recycle these batteries at the end of their useful
lives, when taken out of service within the United States. The RBRCTM program provides a convenient alternative to placing used nickel-cadmium batteries into the trash or
municipal waste system, which is illegal in some areas.
You may contact your local recycling center for information on where to return the spent battery.
Please call 1-800-8-BATTERY for information on Ni-Cd battery recycling in your area. Futaba Corporation of America's involvement in this program is part of its commitment to protecting our environment and conserving natural resources.

Operation Precautions
Warning
ｎ
––––––––––––––– Prohibited Procedures –––––––––––––––
Do not operate two or more models on
ｌ
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) PCM and HRS are different methods of
modulation. Nonetheless the same frequency can not be
used at the same point in time, regardless of the signal
format.
Do not operate outdoors on rainy days
ｌ
, run through puddles of water or when
visibility is limited.
Should any type of moisture (water or snow) enter any
component of the system, erratic opreation 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 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
ｌ
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.

For Your Safety As Well As That Of Others
––––––––––––––– Mandatory Procedures –––––––––––––––
Extend the transmitter antenna to its
ｊ
full length.
If the transmitter antenna is not fully extended the
operating range of the radio will be reduced.
Check the transmitter antenna to be
ｊ
sure it is not loose.
If the transmitter antenna works loose, or is disconnected
while the model is running signal transmission will be
lost. This will cause you to lose control of the model.
Caution
ｎ
Always perform an operating range
ｊ
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 can not 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.
––––––––––––––– Prohibited Procedures –––––––––––––––
Do not touch the engine, motor, speed control or any part
ｌ
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.
––––––––––––––– Mandatory Procedures –––––––––––––––
(Turning on the power switches)
Always check the throttle stick on the
ｊ
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
ｊ
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
ｊ
do so with the engine not running or
the motor disconnected.
You may unexpectedly lose control and create a
dangerous situation.
When operating your model always
ｊ
display a frequency flag on your
transmitter antenna.
When placing the transmitter on the
ｊ
ground during flight preparations, be
sure that the wind cannot knock it over.
If it is knocked over, the throttle stick may be pushed to
full high and the engine will race and create a dangerous
situation.
NiCd Battery Handling Precautions
Special
Chager
Shock
Prohibited
(Only when NiCd batteries are used)
Warning
ｎ
––––––––––––––– Mandatory Procedures –––––––––––––––
For Your Safety As Well As That Of Others
Always check to be sure your batteries
ｊ
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.
When the model is not being used,
ｊ
always remove or disconnect the NiCd
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.
Caution
ｎ
To recharge the transmitter NiCd,
ｊ
use the special charger made for this
purpose.
Overcharging could cause the NiCd battery to overheat,
leak or explode. This may lead to fire, burns, loss of
sight and many other types of injuries.
ｊ
––––––––––––––– Prohibited Procedures –––––––––––––––
Do not use commercial AA
ｌ
size NiCd batteries.
Quick charging may cause the
battery contacts to overheat and
damage the battery holder.
ｌ
Use
prohibited
Do not drop the NiCd battery or expose
ｌ
it to strong shocks or vibrations.
The battery may short circuit and overheat, electrolyte
may leak out and cause burns or chemical damage.
Do not short circuit the NiCd battery
ｌ
terminals.
Causing a short circuit across the battery terminals may
cause abnormal heating, fire and burns.

Storage and Disposal Precautions
–– Prohibited Procedures ––
Do not leave the radio system or
ｌ
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 NiCd batteries into a
ｌ
fire. Do not expose NiCd batteries to
extreme heat. Also do not disassemble or
modify a NiCd 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.
<NiCd Battery Electrolyte>
The electrolyte in NiCd 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.
–– Mandatory Procedures ––
When the system will not be used for
ｊ
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 NiCd battery
may considerably reduce the capacity. A reduction in
operating time will occur even when the batteries are
charged for the recommended time.
Caution
ｎ
–– Prohibited Procedures ––
Do not store your R/C system in the
ｌ
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
operations.
<NiCd Battery Recycling>
A used NiCd battery is valuable resource. Insulate the battery terminals and
dispose the battery by taking it to a battery recycling center.
–– Mandatory Procedures ––
If the system will not be used for a long
ｊ
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.
Caution
ｎ
Other Precautions
–– Prohibited Procedures ––
Do not expose plastic parts to fuel,

The fuel, motor spray, waste oil and exhaust will
penetrate and damage the plastic.
–– Mandatory Procedures ––
Always use only genuine Futaba
