•LOADING THE PENLIGHT BATTERIES

• Remove the battery cover at the rear and insert eight penlight batteries in the correct polarity.

Rear cover mounting screws

Servo reverse
switches
(FP-T2NCR)

Slide in the direction of the
arrow while pushing here.

The batteries can be easily
loaded by inserting them
four at a time from the back.

• Extend the antenna fully and set the power switch to ON.
The

level

meter pointer should deflect to the

silver

zone.

If

the

point­er does not move, or moves very little, check for poor battery con­tact, incorrect battery polarity, or faulty batteries.

• If the pointer of the level meter deflects to the red zone, the range of
the radio waves will become short. When the pointer drops to the
boundary between the silver and red zones, change the batteries.

•The

trim

levers

are

used

to fine

adjust

the

steering

angle.

They

are
used to adjust the neutral position and for correcting the running
posture after the mechanism is mounted. After test running, make
corrections with the rod adjuster, etc. and operate the set with the
trim

levers

in the neutral position

as

much

as

possible.

•SERVO REVERSE SWITCHES
(FP-2NCR)

•This

switch makes

servo

rotation to

another-

direction.

• After fixed servos onto your model, and found
that rotation is wrong-way, switch to another

direction.

•Servo reverse switches are located at bottom of
Transmitter case like drawing below:

system to a ratchet system, install the optional slider.
Then, remove the spring and swing arm.

Install the optional

slider.

Twist with long-nose
pliers.

Remove the
spring and
swing arm.

•CRYSTAL REPLACEMENT

• When changing the band, remove the crystal holder and
change the crystal. (Except 72.75 MHz in USA)

•Futaba Digital Proportional Frequencies (FOR
U.S.A.)

•The

frequency

of Futaba

digital

proportional

sets

can be
changed within their own band. There are 4 different
bands for you to choose from (27 MHz, 50—53 MHz,
72 MHz, and 75 MHz.) Please see chart listed below for

specific frequency and its intended use. Please note there
are specific frequencies allocated for aircraft only and
surface only use.

•The

frequency

can be changed

within

the

same

BAND

by
using a precisely matched pair of Futaba crystals.
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
and the channel designation to the base. (See Drawing)

• It

is illegal to change crystals of 72—75 MHz bands in the

U.S.A.

• Connect the pushrod to each servo horn, then check if the direction of travel of each servo matches the transmitter
Operation.

to the right

When transmitter
stick lever set to the

right

• Operate each servo over its full travel and check if the pushrod binds or is too loose. Applying unreasonable force to

the

servo

horn

will

adversely

affect the servo and

quickly

drain

the

battery.

Be

especially careful

when

using 8.4V.

•Always make the full stroke (including trim) of the servo horns somewhat larger than the full travel. Adjust the
servo horns so that they move smoothly even when the trim lever and stick are operated simultaneously in the same
direction.

• Be alert for noise.
Always solder a noise killing capacitor to the running motor. If metal parts touch each other due to vibration, noise
will

be generated and

cause

the

receiver

servos

to

operate erroneously.

We

recommend

the

use

of

noiseless parts.

Even

though

the

receiver antenna

is

long,

do

not

or

bundle

it.

• 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 requesting repair of trouble that has oc­curred suddenly of from long use, describe the
trouble symptoms in as much detail as possible.

This will facilitate detection of the trouble point
and shorten the repair period greatly.

•Defects caused by faulty materials or workmanship

will

be

corrected

free

of

charge.

•This limited warranty is null and void if the set has

been tampered with or disassembled.
Refer to warranty statement for details.

•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.

Release the connector.

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

has

been precisely tuned

to

the

full

length of the stock antenna.

2)

Excess

antenna wire should

NOT

be

tightly
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.

SNOW IS WATER

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._____
