•FEATURES
The PCM1024A was specially-developed to meet the needs of the serious and demanding
R/C hobbyist. Numerous features make this system adaptable to a wide variety of complex
radio control stunt and scale aircraft. This is the most advanced system available for FAI
Precision Acrobatic (F3A) competition. The built-in microprocessor utilizing PCM (Pulse
Code Modulation) makes this set very versatile and extremely noise and deadpoint resistant.
Please read this manual carefully before using your set.

PRECAUTIONS
NOTE: A separate servo on each aileron will allow use of special transmitter control mixing and differen-
tia/ functions.
• 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 movement.
• 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 function
(See
page
14).
•
Operate each
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 batteries 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 f ull
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.

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-8B (2)
battery charger to the transmitter charging
socket, and connect the 3P connector to the
airborne NR-4J 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-4J
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,
Charging Method
AC-120V
TX (Transmitter)
then charge it a full 15 hours.
•The
amount of time
remaining
before the batteries must be recharged can be estimated by
checking the integrated timer at the moment
the TX battery alarm sounds (antenna extended).
• Leaving batteries in the discharged state for a
long time will adversely affect their capacity
and life.
•The TX and R X 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 airborne NR-4J Nicd battery pack ca n be used
for about 7 flights when 6 servos are used and
about 4 flights when 10 servos are used.

•OPERATING INSTRUCTIONS.
• When adjusting and setting the transmitter functions, connect the receiver and servos, and
make the adjustments while observing the operation of the servos.
• Alternatively, when studying the operation of transmitter functions, remove t he transmit-
ter RF module (to reduce battery drain). The effects of adjustments can be viewed on the
SRV program screen (See page 48).

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
restarts from 00:00.
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 capacity and monitoring total flying time. Maximum count is 59:59:59.

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 (in 20 rpm increments).
Setting Method
1) Display the standard screen, and press the
TAC 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 fr om 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 stabilize, then read the measured value. Maximum
speed range is 50,000 rpm.
Low Battery Warning
Low Battery Warning
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.
Back Up Warning
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
battery is probably dead, or there is trouble in
the system. To locate the cause, call your Futaba
service center. The back up lithium battery life
depends on the usage state, but is about 5 years.

ADJUSTMENTS AND FLIGHT TECHNIQUES
ADJUSTABLE TRAVEL VOLUME
• The ATV function is used to adjust servo travel limits. Serv o 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 sa me 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
cursor keys.
4)
Operate the control stick, lever, or switch of
the channel to be adjusted to its maximum
and
extent in the desired direction. The cursor wil l
automatically move to the left or right confirming the direction to be set.
5) Servo endpoint limits can be set by pressing

the left hand throw is set to 100%. Note t hat on
the right side. Dual Rate ON (Low Rate) and
Trim throw limits are also reduced to 50% of
normal.
