•FEATURES
The PCM1024H was specially-developed to meet the needs of the serious and demanding
R/C Helicopter hobbyist. Numerous features make th is system adaptable to a wid e variety
of complex radio control helicopters and stunt and scale aircraft. This is the most advanced
system available for FAI R/ C Helicopter (F3C) 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.
TRANSMITTER FP-T9VHP

diverse applications for the control of complex
helicopters and fixed-wing aircraft.
• Four kinds of "swash plate mixing" are avail-
able for direct control and mixing of cyclic and
collective pitch functions (CCPM).

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
•
Operate
for binding and/or excess slop in the linkage or
pushrod. Unreasonable force on the servo arm
may damage

• 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.

• Connect the DIN connector of the FBC-6B (2)

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)

Charger FBC-6B (2)
RX (receiver)
then charge it a full 15 hours.
• The amount of operating time 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 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 ar e used.

• 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 the transmitter RF module (to reduce battery drain). The effects of adjustments can be viewed on th e
SRV program screen (See page 50).
• Set the power switch to the ON position. The standard screen shown below appears on the

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 th e 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 O N time. It is very useful
for estimating remaining Nicd battery capac-
ity and monitoring total flying time. Maxi-
mum 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 fin 20 rpm increments).

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.
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 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.

EXPONENTIAL/VTR
Exponential or VTR functions can be used to change the servo response curve from the
normal Iinear operation. This can be very helpful if control response is either sluggish or too
sensitive near the neutral position. Maximum servo deflection limits (set by ATV and/or
AFR) remain the same.

CH8.

used, when desired, on "neutralizing" controls
such as AI L, ELEV. and RUD.
The TYPE 2 Curve is exponential in one direction over the full stroke of the control stick or
lever. This type is normally used w ith functions
such as T HR .
• The amount of exponential can be varied from
0% to 100% in 4% steps. By using positive or
negative exponential with either the TYPE 1 or
TYPE 2 EXPO Curves, a total of four different
types of Exponential control response can be
selected.
TYPE 1 Positive
TYPE 2 Positive
With this type of curve, control response will be made
more sensitive near neutral and less sensitive as the stick
is deflected farther towards its extreme limits.
TYPE 1 Negative
With this type of curve, control response will be
"softer" around neutral and increase as the stick is
deflected farther.
• When V TR is used, servo response remains linear, but the response is automatically switched to a higher
rate at a ce rtain (adjustable) point in the control stick deflection.
• The i nit ial response rate is the same as the Dual Rate ON rate (See page 18).
• Maximum servo travel limit is still controlled by ATV and/or AFR.

key is pressed, the rate is preset to 0% (0% =
normal or linear).
5) In the V TR mode, the "rate" adjustment is
used to adjust the stick position at which the
servo response changes from Low to High.
The initial (Low) rate is adjusted by the D/R
adjustment program (See page 18).
6) Channels 5 through 8 can be displayed and set
by pressing the program key.
In the above example, a TYPE 2 Negative Exponential Curve is shown. This type is often
helpful on the Throttle channel. Depending on
the carburetor design and linkage, actual power
transition can be made more linear in relation to
stick movement. (About —20% is a good initial
setting for fixed-wing aircraft).
