PRECAUTIONS
•Connect the receiver, servos, switch harness,
etc. as shown in the figure. Extend the trans-
mitter and receiver antennas to their full
length. Turn on the transmitter power switch,
then turn on the receiver power switch. The
servos will go to their neutral position. Move
the transmitter sticks one at a time to check
that each servo follows its control stick move-
ment.
•Connect pushrods and linkages to the servos
and check that the direction of travel of each
servo matches the direction of movement of its
control stick. If a servo does not move in the
proper direction, use the servo reversing func-
tion (See page 14).
• Operate each servo to its full extent, and check
for binding and/or excess slop in the linkage or
pushrod. Unreasonable force on the servo arm
may damage
the servo and will drain the bat-
teries very quickly.
• Adjust servo output arms and aircraft control
linkage as necessary so that each servo moves
smoothly throughout its full range of travel,
even when the control stick and trim lever are
operated simultaneously in the same direction.
• Be alert for possible sources of electrical noise.
This set is noise-resistant, but the use of noise-
less parts is recommended.
•When installing the switch harness, make sure
that the switch can move smoothly, to its full
extent in each direction without binding.
Install the switch where it will not be exposed
to engine oil, dust, dirt, etc. The switch can be
installed inside the fuselage and operated from
the outside with a piece of wire.
• Do NOT shorten the receiver antenna or fold it
back along its length.
•When installing the servos, tighten the mount-
ing screws so that the rubber grommets
are
compressed slightly. If the screws are too tight,
the vibration-dampening
effect of the grommets
will be lost and servo
damage may occur.
• The crystal can be changed
without opening the receiver
case. Always use a Futaba
matchedTX/RXcrystalset
to change frequencies.
• Extra servo output arms are
supplied.Usethem as needed.
• Use extension cords where necessary. RF
"chokes" are not required with the PCM
receiver.
• Wrap the receiver and the airborne battery
pack separately in foam padding. Padding
should be wrapped loosely for maximum vibra-
tion protection. Place each inside a waterproof
plastic bag and secure the end of the bag with a
rubber band.
• Use the rubber bands wrapped around the
receiver to hold the servo and switch leads.
•After installation and adjustments are com-
plete, perform a range check by collapsing the
transmitter antenna and extending the receiver
to its full length and operating the transmitter
from a distance of 60 to 90 feet from the
receiver (aircraft). The system should operate
normally at this range.

BATTERY CHARGING INSTRUCTIONS (Transmitter and Receiver Nicd Batteries)
Before operating your system, recharge the Nicd batteries as follows:
•Connect the DIN connector of the FBC-6B (2)
battery charger to the transmitter charging
socket, and connect the 3P connector to the
airborne NR-4LB Nicd battery pack and plug
the battery charger into a 120VAC outlet as
shown in the figure.
•The TX and RX LEDs light to show that bat-
teries are being charged. The Nicd batteries can
also be charged through the DSC-CHG cord by
connecting the CHG adaptor to the charger as
shown in the figure. This allows the NR-4LB
airborne Nicd pack to be charged without
removing it from the model.
•Normally recharge the battery for about 15
hours. If it has not been used for some time,
discharge and recharge it two or three times,
,TX (transmitter)
then charge it a full 15 hours.
• The amount of operating time before the bat-
teries must be recharged can be estimated by
checking the integrated timer at the moment
the TX battery alarm sounds (antenna ex-
tended).
• Leaving batteries in the discharged state for a
long time will adversely affect their capacity
and life.
• The TX and RX Nicd batteries can be charged
simultaneously or independently.
• A fully-charged TX battery can be used for
about 10 flights of 10 minutes each. The air-
borne NR-4LB Nicd battery pack can be used
for about 7 flights when 5 servos are used.

TIMER
The TIMER function can be used to monitor flying time, fuel consumption, at contests,
etc. Four different timing functions are available: Up Timer, Down Timer, Rhythmic Timer,
and Total (Integrating) Timer.
Timer Functions
1) Up Timer This timer counts up from zero in
1 second steps. Its maximum count is 59:59.
When the alarm time is set, a buzzer begins to
sound 10 seconds before the set time is up.
The buzzer also sounds at each 1 minute
interval. When the time reaches 59:59, timing
restartsfrom00:00.
2) Down Timer This timer counts down from
the set time in 1 second steps. Operation is
otherwise the same as the Up Timer.
3) Rhythmic Timer This is a 0.1 second cyclic
timer. A buzzer sounds at each set alarm
interval. When the set alarm interval elapses,
the counting automatically restarts.
4) Total (Integrating) Timer This timer records
the total transmitter ON time. It is very useful
for estimating remaining Nicd battery capac-
ity and monitoring total flying time. Maxi-
mum count is 59:59:59.

ADJUSTMENTS AND FLIGHT TECHNIQUES
TACHO METER
Tachometer
The tachometer function is used to measure the speed on one to five-bladed propellers, etc.
Speed (rpm) is measured up to a maximum of 50,000 rpm fin 20 rpm increments).
Setting Method
1) Display the standard screen, and press the
program key.
2) Press program key to to select the
number of blades.
Ex: for a two-bladed propeller.
3)
Measure the speed by pointing the built-in
sensor on the transmitter (center of the left
side panel) at the front or rear of the propeller
disc from a distance of 8 to 12 inches. Be sure
the model is restrained by an assistant, and be
very careful of the rotating propeller.
Allow a few seconds for the display to stabi-
lize, then read the measured value. Maximum
speed range is 50,000 rpm.
LowBatteryWarning
This function operates when the transmitter
Nicd battery voltage drops below 8.5 volts. The
characters "LOW BATTERY" blink on the
screen, and a buzzer sounds. When this occurs,
land immediately and recharge or replace the
Nicd battery pack.
[12]

Back Up Warning
When the stored data is lost, the characters
"BACK UP" blink on the screen and a buzzer
sounds. When the power switch is turned on
again, the error display disappears and all the
settings return to the factory-set values. When a
Back Up error occurs, the back-up lithium bat-
tery is probably dead, or there is trouble in the
system. To locate the cause, call your Futaba

FAIL SAFE
Fail Safe
Fail Safe and Hold Functions
The HOLD (Hold) and F/S (Failsafe) functions
are designed to allow the aircraft or helicopter to
"fly through" a momentary loss of signal or very
strong interference, rather than experiencing the
familiar
"glitch" as the servos react violently to
the unwanted signal. These functions cannot be
expected to prevent a crash however, if the
normal signal interruption is of sufficient dura-
tion.
The HOLD function stops the servo at the posi-
tion held just before the normal signal is lost.
When a normal signal is again received, the Hold
function is released.
The FAILSAFE
function will move a servo to
neutral or a pre-set position when the normal
signal is interrupted for 1 second or longer (The
system will remain in HOLD for the first 1
second of signal loss). When a normal signal
resumes, FAILSAFE is released.
BFS (Battery Fail Safe) Function
The BFS function moves the throttle (CH3)
servo to the pre-set Fail Safe position when the
airborne power supply is nearly exhausted. If no
Fail Safe position has been set, the throttle servo
will move to medium slow (neutral).
BFS can be released by lowering the throttle
Stick past the release point (adjustable), or with
the CH9 switch. Throttle control is then regained
for about 30 seconds. At the end of 30 seconds,
BFS
will re-engage and the throttle will again
move to the Fail Safe position. Whenever BFS
engages, land the aircraft as quickly as possible
and recharge or replace the Nicd battery pack.
[14]

Fail Safe and Hold General Instructions
Fail Safe
• F/S or HOLD can be selected for each channel
(1
to 8).
•Channels selected for HOLD will remain in
HOLD until a normal signal resumes. Those
selected for F/S will move to their pre-set posi-
tions after 1 second of signal interruption.
• F/S SET simultaneously stores the desired Fail
Safe position in the transmitter memory and
sends it to the receiver.
•The F/S data is automatically sent to the
receiver when the transmitter is first turned ON
and at one minute intervals as long as the trans-
mitter is left on.
• The F/S position can be checked with the
program key.
• Only the Throttle channel (CH3) can be set for
Battery Fail Safe.
Fail Safe Setting
1) Display the EDIT screen, then select the
FAILSAFE screen by pressing the pro-

Battery Fail Safe Setting
1) Set the Failsafe position on the throttle chan-
nel
(CH3) as described above. A position
slightly above the minimum engine idle
speed
is recommended.
2) BFS Release Point Setting (When
THR is
designated as the release channel)
• Move the cursor to the B/FS-RESET line of
the FAILSAFE screen with the or
cursor key.
• Select the BFS release channel with the
or program key.
•Set the throttle stick to the desired BFS
release point and press the program
key. This designates CH3 (Throttle) as the
release channel and sets the stick release
point simultaneously.
3) To release BFS by the CH9 switch, press the
program key.
• BFS can be released by the CH9 switch only
when the switch is moved to the upper
position. If the CH9 switch is in the lower
position, BFScannot be released.
• In the BFS release state, the characters 0%-
RESET are displayed on the B/FS-RESET
line of the FAILSAFE screen.
4) If Battery Fail Safe is not desired, press the
program key (when the cursor is on the
B/FS-RESET line).
The BFS function will
then be disabled.

ADJUSTMENTS ANDFLIGHT TECHNIQUES
ADJUSTABLE TRAVEL VOLUME
• The ATV function is used to adjust servo travel limits. Servo travel can be adjusted independently in each
direction from neutral. Adjustment from 30% to 110% of normal full travel (throw) is possible.
• NOTE: When servo travel is changed by ATV, the limits of trim throw and the Dual Rate ON (Low Rate)
limits are increased or reduced by the same percentage.
• ATV limits are displayed by a bar graph and numbers. The point at which the cursor moves from left to
right, as the stick or lever is moved, is the electrical neutral point of that channel.
Setting Method
1) Select the EDIT screen, then select the ATV
program screen by pressing the program
key.
2) Rate data (endpoint limits) for Channels 1 to
4 is displayed on the screen. To display and
adjust Channels 5 to 8, press the program
key. Rate data for Channels 5 to 8 will be
displayed.
3) Select the channel to be set with the and
cursor keys.
extent in the desired direction. The cursor will
automatically move to the left or right con-
firming the direction to be set.
5) Servo endpoint limits can be set by pressing
the and program keys while holding
the appropriate stick or lever in the same
direction. Pressing the program key will
return the set limit to 100%.
6) When you are finished, press the key to
return to the EDIT screen.
4) Operate the control stick, lever, or switch of
the channel to be adjusted to its maximum
In the example shown, the CH1 (Aileron) right throw is reduced to 90%.

ADJUSTABLE FUNCTION RATE
AFR is a servo endpoint limiting function, similar to ATV with one exception:
AFR limits only the Dual Rate OFF (High-Rate) servo travel. Trim throw/and Dual Rate
ON (Low Rate) limits are unaffected (unless AFR is reduced below the D/R ON limit).
SettingMethod
1) The setting method for AFR is the same as for ATV (See page 16).
2) Select the EDIT screen and press the AFR program key.
In the bar graph illustration below, the right
hand throw is reduced to 70% of normal throw
by AFR. Note that the Dual Rate ON (Low
Rate) limit and Trim throw limits remain the
same on both sides (Compare with the ATV
illustration on page 16).

DUAL RATE
Dual Rate functions allow the modeler to switch servo travel limits in flight, thus varying
the control sensitivity for different flight conditions or maneuvers.
• Dual Rate functions are available on CH1 (Aileron), CH2 (Elevator), and CH4 (Rudder/Tail Rotor).
• Dual Rate ON (Low Rate) limits can be adjusted from 30%to 100% offull throw.
• If servo travel is reduced by ATV, the D/R ON throw will be 30% to 100% of the limit set by ATV (in
D/R OFF). If AFR is used, the D/R ON limit is unaffected, and will be 30% to 110% of normal (full)
throw.
• Dual Rate ON limits can be adjusted independently in each direction from neutral.
•There are three D/R ON/OFF Switches. Control of the three D/R functions can be assigned to these
switches in any combination the modeler desires, or D/R functions can be switched ON and OFF auto-
matically according to the position of the Throttle/Collective stick.
•The ON/OFF directions of the D/R switches can be reversed using the PARAMETERS program screen
(See page 46).
• In the AUTO D/R mode, the D/R functions can be turned ON and OFF according to the position
(adjustable) of the T/C stick.
