•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

• Programming data is displayed pictorially and
graphically on a large, easy-to-read
(Liquid Crystal Display) panel. Programming
and Cursor keys allow convenient adjustment
of aircraft functions.

•"1024"
encoder format provides unexcelled servo reso­lution and response time.

•RF
circuit and PCM transmission.

• Precise control is made possible by three dif­ferent endpoint adjustment functions: Adjust­able Travel Volume (ATV), Adjustable Func­tion Rate (AFR), and Adjustable Trim Rate.

• Dual R ates, Exponential, and Variable Trace
Rate (VTR) functions provide unlimited flexi­bility

• There are many functions for collective pitch,
throttle, and rudder, including four adjustable
pitch and throttle curves (plus inverted pro­gram). Precise and convenient adjustments
enable optimum helicopter performance.

• Four programmable mixing circuits allow many

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).

•Programming for up to 6 different models (in-

cluding model name) can be stored in the trans-

mitter memory. Memorized

by a 5 year lithium battery.

• Accessory "Sub-Trimmers" ar e provided on the

transmitter front for convenient field adjust­ment of frequently-used functions.

PRECAUTIONS

•Connect

etc. as shown in the figure. Extend the trans­mitter 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

•

Operate

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

•After installation and adjustments are com­plete, 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.

Before operating your system, recharge the Nicd batteries as follows:

Batteries)

• 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.

that bat­teries 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,

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.
