SYSTEM
•The NEW ATTACK, NEW ATTACK-R is a high performance 2 channel digital proportional
R/C set based on the acclaimed ATTACK and has a built-in BEC (Battery Eliminator
Circuitry) system.
Since the power receiver and servo power is supplied from the running
Nicd battery, there is no troublesome wiring and the vehicle can be made
lighter.
•The NEW ATTACK-BFR is the newest 2 channel digital proportional R/C set with a built-
in ASP (Adjustable Safety Position) system, plus the functions of the NEW ATTACK.
It is a safety system which protects the vehicle against loss of control due
to a discharged Nicd by detecting a drop in the voltage of the running
Nicd battery which is a shared power supply and stops the vehicle.
Thank you for purchasing a Futaba digital proportional radio control set.
Please read this manual carefully before using your set.

FEATURES OF NEW ATTACK NEW ATTACK-R AND NEW ATTACK-BFR
The NEW ATTACK, NEW ATTACK-R has a BEC function.
The NEW ATTACK-BFR has BEC & ASP functions.
•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.
(Installed in NEW ATTACK, NEW ATTACK-R and NEW ATTACK-BFR.)
•The
ASP (Adjustable
Safety
Position)
system
prevents
loss
of
steering
control.
It
is
a
safety
system
which protects the
vehicle
against
loss
of control due
to a discharged
Nicd
by detecting a drop in the voltage of the shared power supply Nicd battery and automatically
sets
the
throttle
servo
to the
drive
motor off position
preset
at the transmitter
then allows steering with the remaining power before steering control is lost. When the
voltage of the running Nicd battery recovers, ASP is automatically reset and the normal
running functions are recovered by turning on the transmitter power switch. (Installed
in NEW ATTACK-BPR)
World's first safety system that allows running of the vehicle up to the finish
line while using the capacity of the power supply to the fullest without a loss of
steering control even when the voltage of the running Nicd battery drops.
•Transmitter is Built-in servo reverse switches. (New ATTACK-R, NEW ATTACK-BFR)
TRANSMITTER FP-T2NBL/T2NBR/T2NBFR
SERVO FP-S128
SMALL, RUGGED, HIGH NEUTRAL SERVO
•ASP (Adjustable Safety Position) system allows safe
recovery without a loss of steering control. (T2NBFR
only)
•New swivel stick system that allows selection
of the
stick lever operating direction over a range of 10°.
•Racing specification short
aluminum stick lever makes
operation extremely easy.
•New
neutral
lever
allows setting of
the
neutral
position
of the throttle stick in two stages. Perfectly matched to
the throttle position of motor and engine cars. 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. (T2NBR, T2NBFR)
• Level meter shows the state of the battery at a
glance.
•Crystal
can be changed from the outside. (Except 72.I
75MHz)
• Hook. Optional neck strap can be used.
RECEIVER FP-R102GF
•BEC (Battery Eliminator Circuitry) system allows
sharing of the running Nicd battery and eliminates the
need for a regulator and diode.
•High
performance 2 channel
receiver
with
ASP system
when used with the proper transmitter.
•Crystal socket uses a new type of highly reliable subminiature pins. Reliability is increased and the crystal
can be changed from the outside.
•Skew type armature motor.
Movement of the trimmer by even one notch is tracked
by a skew type motor which displays a performance
near that of a coreless motor.
• New indirect drive potentiometer improves
vibration
and shock resistance and neutral accuracy.
• Futaba low-power custom 1C provides extremely
high
torque, narrow dead band, and superior tracking.
• Fiberglass reinforced PBT (polybutylene terephthalate)
injection molded servo case is mechanically strong
and
invulnerable to glow fuel.
•Strong polyacetal resin ultra-precision servo gear fea-
tures smooth operation, positive neutral, and very little
backlash.
• Fiberglass reinforced epoxy resin PC board with thru-
the-hole plating improves servo amp vibration and shock
resistance.
• Three pin connector eliminates faulty contact and improves reliability against vibration and shock. Housing
has a reverse insertion prevention mechanism.
•Special grommet simplifies mounting
of the servo and
has an excellent cushioning effect.
•Six special adjustable splined horns.
•High 48.7oz.jn (3.5kg-cm) maximum output torque
allows use in almost any model.

•LOADING THE PENLIGHT BATTERIES
• Remove the battery cover at the rear and insert eight penlight batteries in the correct polarity.
Remove the cover by push-
ing here and sliding down.
Load the eight pen-light
batteries while paying care-
ful attention to their-polarity.
• 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
(NEW ATTACK-R. NEW ATTACK-BFR)
• This switch makes servo rotation to anotherdirection.
• 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:
