The ATTACK-SPORT has a BEC function

• The BEC (Battery Eliminator Circuitry) system is a high performance constant voltage
circuit (regulator). Since the running Nicd battery can also be used as the receiver servo
power supply, there is no troublesome wiring and the vehicle can be made lighter.

• Transmitter is Built-in servo reverse switches. (FP-2NCR)

TRANSMITTER FP-T2NCS/T2NCR

•Racing specification short aluminum stick lever makes

operation extremely easy.

•The

stick

can

be

changed

to a ratchet system

by

installing an optional slider.

• Servo reverse switches (steering & throttle).
Since each servo can be switched between forward

and
reverse from the outside of the transmitter, linkage
hookup is extremely easy. (T2NCR)

• Level meter shows the state of the battery at a glance.

•Crystal can be changed from the outside. (Except 72/
75 MHz

in

USA)

RECEIVER FP-R102JE

•Miniature and lightweight high-performance AM
receiver with built-in BEC is realized by using chip parts.
(20% smaller and 35% lighter than our R102GF.)

• Intermodulation interference characteristic improved
substantially by using a new circuit system AIC circuit.

•Reliability is improved further by using the unique
Futaba custom decoder 1C.

• Newly designed case is small and easy-to-use.

• High sensitivity design by built-in RF amp.

•High-performance built-in BEC system can handle
power supply voltages up to 8.4 V.

RUGGED, LOW-PROFILE SERVO

•The

PP-S148

design that can be easily mounted in all models.

•Vibration
further by using a direct wiring system which directly
connects the servo amp, motor and potentiometer.

•The

height of
torque, high speed, and smooth movement equal to that
of the coreless servo have been realized by using a new
small, high-performance motor. (Output torque 42
oz-in <3kg, cm), operating speed 0.22 sec/60°).

• New indirect drive/completely sealed potentiometer
substantially improves vibration
and neutral accuracy.

•Unique Futaba power-saving custom 1C provides high
starting torque narrow dead band, and excellent track­ability.

•Fiberglass P8T (polybutylene terephthalate) servo case
is mechanically strong and is invulnerable to glow fuel.

•Strong
smooth operation, accurate neutral, and minimal back­lash.

•Fiberglass epoxy PC board with THRU-THE-HOLE
plating improves the servo amp vibration and shock
resistance.

•Thick plated connector pins eliminate the problem
faulty contact, improve reliability against shock
vibration, and prevent reverse insertion.

•Special pad grommets simplify mounting
and are extremely vibration-resistant.

•Six kind of special adjustable horns are available.

bands for you to choose from (27 MHz, 50—53 MHz,

are specific frequencies allocated for aircraft only and
surface only use.

However, Futaba recommends that you return your
system to our factory service department for frequency
changing, as turning may be necessary for proper opera­tion. Changing frequency from one band to another is
NOT possible.

•Always change frequency flag when frequency is changed.
The frequency flag is to be attached to the top of antenna

Scissors

• A spare horn is provided. Use it as required.

•Wrap the receiver in sponge rubber and wrap rubber bands around the sponge rubber. Mount the receiver so it is
not exposed to vibration, does not touch the frame, and does not move.

•When the receiver is installed on a board or used where it may be splashed with mud and water, place it in a plastic
bag, etc. and wrap a rubber band around the open end of the bag to waterproof and dustproof the receiver. After use,
remove the receiver from the bag to prevent condensation.

• Use the rubber bands wrapped around the receiver to hold the servo and switch leads.

•After mounting is complete, recheck each part, then check the transmitting range by making the transmitter antenna
as short as possible and extending the receiver antenna fully and operating the set from a distance of 20m to 30m. The
movement of each servo should follow the movement of the transmitter sticks.

• The crystal can be changed from the outside of the receiver case. (Except 72/75MHz in U.S.A) Always use a Futaba
transmitter and receiver crystal pair as the replacement crystals.

Your NEW FUTABA Digital Proportional R/C Sys-
tern is guaranteed against defects in workmanship
and material for 180 days from the date of purchase
when the attached registration card is returned to
us within ten days of purchase.
This Guarantee is null and void if the R/C system
has been improperly handled, damaged in a crash, or
tampered with and does not cover the replacement
of plastic housings or electronic components
damaged due to the use of improper voltages.
When service is required, please take your equip­ment to your local authorized service station or ship
it directly to us. All postage, shipping, and insurance
charges must be paid by the user.

•WHEN VEHICLE WILL NOT BE USED

Be sure and release the connector of running
Nicd battery except when you are on the way
to the starting line.

When not using the
connector, set the
switch to OFF.

To obtain the best possible range (car to transmitter
distance) and reduce the possibility of interference,
please observe these antenna routing instructions.

Failure to follow these guidelines can result in loss

of control or limited range

1) NEVER cut your receiver's antenna wire.
Your system

2)

Excess

coiled. To safely store the excess wire make
an antenna shortener from a small piece of stiff
cardboard. This will provide maximum reception
and prevent tangling and breakage of the wire.

3) When routing the antenna wire to the antenna
tube keep the wire away from battery and speed
control wiring. The high power of the NiCd

battery creates electrical "noise" which can cause

interference.

Remember that operating your FX10 on snow
or in wet areas is not recommended. Melted
snow becomes water which will damage or short
out your system's electronics._____
