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 mu-
nicipal 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 Cor-
poration of America's involvement in this program is part of its commitment to protecting our environ-
ment and conserving natural resources.
NOTE: Our instruction manuals encourage our customers to return spent batteries to a local recycling
center in order to keep a healthy environment.
RBRCTM is a trademark of the Rechargeable Battery Recycling Corporation.
Warning: This product contains a chemical known to cause cancer and birth defects (or other
reproductive harm).

FOR SAFETY
FOR SAFETY
Precautions During Flight
WARNING Do not fly in the following places:
-Near other R/C flying fields (within
about 3km)
-Near people on the ground, or objects
in the air
-Near homes, schools, hospitals, or
other places where there is a lot of
people
-Near high tension lines, high struc-
tures, or communication facilities
Radiowave interference and obstructions
may cause a crash. A crash caused by
trouble in the R/C set, or the model itself,
may cause death or property damage.
Meaning of Special Markings
Pay special attention to the safety at the parts of this manual that are indicated by the
following marks.
DANGER
Mark Meaning
CAUTION
WARNING
To ensure safe use, observe the following precautions.
Do not fly when you are tired,
sick, or intoxicated.
Fatigue, illness, or intoxication will cause a
loss of concentration or normal judgment
and result in operation errors and a crash.
Symbol: ; Prohibited ; Mandatory
Procedures which may lead to a dangerous condition and
cause death or serious injury to the user if not carried out
properly.
Procedures which may lead to a dangerous condition or
cause death or serious injury to the user if not carried out
properly, or procedures where the probability of superficial
injury or physical damage is high.
Procedures where the possibility of serious injury to the user
is small, but there is a danger of injury, or physical damage,
if not carried out properly.
4YBF
Do not fly simultaneously on the
same frequency.
Interference may
cause a crash.
*Use of the same frequency
will cause interference even
if the modulation method
(AM, FM, PCM) is different.
Do not fly on rainy or windy
days, or at night.
Water will penetrate
into the transmitter
and cause faulty op-
eration, or loss of con-
trol, and cause a
crash.
3
FOR SAFETY
Extend the antenna to its
full length.
If the antenna is
collapsed, the ef-
fective range of
the radiowaves
will become
shorter.
Always test the digital proportional R/C
set before use.
Any abnormality in the digital proportional R/C set,
or model, may cause a crash.
*Before starting the engine, check that the
direction of operation of each servo matches
the operation of its control stick. If a servo
does not move in the proper direction, or op-
eration is abnormal, do not fly the plane.
Check that the transmitter antenna is not loose.
If the transmitter antenna comes off during use, control will be
lost and the model will crash.
(In case of a set w/ frequency board)
CAUTION
Do not touch the engine,
motor, and speed control
during and immediately
after use.
They are hot and will cause a burn.
When adjusting the digital
proportional R/C set, al-
ways stop the engine, ex-
cept when necessary.
If the engine suddenly goes to high
speed, it may cause an injury.
When flying, always in-
stall the frequency board
to the transmitter an-
tenna.
When the frequency was changed,
also change the frequency board.
When placing the transmitter on the
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 cre-
ate a dangerous situation.
Test
When turning on the power switch
After setting the transmitter throttle lever to
maximum slow,
1. Turn on the transmitter power switch,
2. Then turn on the receiver power switch.
When turning off the power switch
After stopping the engine,
1. Turn off the receiver power switch,
2. Then turn off the transmitter power switch.
If the power switch is
turned off in the opposite
order, the engine may go to
full throttle unexpectedly
and cause an injury.
*Maximum slow: Direction in
which the engine or motor runs at
the slowest speed.

FOR SAFETY
(If using a Ni-cd battery)
Ni-cd Battery Charging Precautions
WARNING
Always charge the nicd
battery before each flight.
If the battery goes dead during
flight, the plane may crash.
Charge the digital proportional R/C nicd
battery with the special charger, or digi-
tal proportional R/C quick charger, sold
separately.
Overcharging may cause burns,
fire, injury, blindness, etc. due to
overheating, breakage, electro-
lyte leakage, etc.
CAUTION
Do not use commercial nicd penlight
batteries.
During quick charging, the bat-
tery holder contacts may over-
heat and damage the equip-
ment, or prevent charging.
Do not short the nicd battery connec-
tor terminals.
Shorting the terminals may cause sparking and
overheating and result in burns or fire.
Do not drop or apply strong
shock to nicd battery.
The battery may be shorted and cause
overheating or breakage and electro-
lyte leakage and result in burns or
damage by chemical mater.
Storage and Disposal Precautions
WARNING
Do not leave the digital proportional R/C set, battery, model airplane, etc.
within the reach of small children.
Touching and operating the digital proportional R/C set, or licking the battery, may cause
injury or damage due to chemical matter.
Do not throw the nicd battery into a fire or heat the nicd battery. Also, do
not disassemble or rebuild the nicd battery.
Breakage, overheating, and electrolyte leakage may cause injury, burns, or blindness.
5
FOR SAFETY
When not flying the model, store the digital proportional R/C set with the
nicd battery in the discharged state. Recharge the nicd battery before the
next flight.
If a partially discharged nicd battery is recharged many times, its memory effect will reduce
the flight time substantially and may cause a crash, even if the battery is recharged.
Nicd battery recycling
Used nicd batteries are an important resource. Stick tape over the terminals and take the used batteries
to a nicd battery recycling center.
CAUTION
Do not store the digital proportional R/C
set in the following places:
-Where it is very hot (40C/104F or more) or very
cold (-10C/-14F or less).
-Where the set will be exposed to direct sunlight.
-Where the humidity is high.
-Where there is strong vibration.
-Where it is dusty.
-Where there is steam and heat.
Storing the digital proportional R/C set in the places
above may cause distortion and trouble.
If the digital proportional
R/C set will not be used
for a long time, remove
the batteries from the
transmitter and the
model and store them in
a dry place.
If the batteries are left in the trans-
mitter and model, the battery elec-
trolyte may leak out and degrade
the performance and shorten the
life of the transmitter and model.
Nicd battery electrolyte
The electrolyte in the nicd battery is a strong alkali and can cause blindness if it gets in the eyes. If you
get the electrolyte in your eyes, immediately wash your eyes with water and see a doctor. If you get the
electrolyte on your skin or clothes, it may cause a burn. Immediately wash it off with water.
Other Precautions
CAUTIONS
Do not get fuel, waste oil,
etc. on plastic parts.
The plastic may melt and fail to
function.
Always use Genuine Futaba transmit-
ter, receiver, servos, FET amp, nicd
battery, and other optional parts.
Futaba is not responsible for damage, etc. caused
by the use of parts other than Genuine Futaba
parts. Use the parts described in the instruction
manual and catalogs.
