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.
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.

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

•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.
• 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.

If the neutral lever is moved, the

steps as shown in the figure.
When the neutral lever is up, the
throttle stick can be adjusted to
a total of 54°, 27" up and 27°
down, from the neutral position. This position is best for
electric cars and other models
with which the center of the
speed controller is the neutral
position.
•CHANGING THE THROTTLE STICK FROM A
SELF NEUTRAL SYSTEM TO A RATCHET

•When changing the throttle stick from a self-neutral
system to a ratchet system, install the optional slider.
Then, remove the spring and swing arm.

•CRYSTAL REPLACEMENT
•When changing the band, remove the crystal holder and
change the crystal. (Except 72. 75MHZ)
When the neutral lever is down,
the throttle stick can be adjusted to a total of 54°, 36° up
and 18° down (2-to-1), from the
neutral position. This position is
best for engine-drive cars or
other models with which the
speed controller neutral position
is offset.
•Futaba Digital Proportional Frequencies (FOR
U.S.A.)
• The frequency of Futaba digital proportional sets can be
changed among bands (1) ~ (6) on the 27MHz band only.
• However, a 27MHz band set cannot be changed to 72MHz
band, and vice versa.
• Therefore, always, attach the correct frequency flag to
the end of the transmitter antenna. Each frequency band
has its own designated color, as stated above. The frequency flag is intended for identification purposes.
• Also change the frequency flag when frequency is
changed.
• Futaba paired crystals are precisely matched. Always use
a Futaba crystal set (transmitter, receiver) when changing
the frequency.
• It is illegal to change crystals of transmitter on the 72-75
MHz bands in the U.S.A.

•A common power supply regulator and diode may also be supplied with the speed controller, depending on the vehicle kit. Since they cause a voltage drop, always remove them.
TO BUYERS OF THE NEW ATTACK-BFR (FP-R102GF)
When using a Futaba motor control amp (MC-106,
106B, 108, 109, 110, etc.) instead of the speed
controller supplied with the vehicle, turn off the
ASP system as shown in the figure.
Insert the ASP release connector packed with the
set at this 2P connector '

•Set the transmitter power switch to ON, then set the receiver power switch to ON. The servos stop near the neutral
position. Operate the transmitter sticks and check if each servo faithfully follows operation of the sticks.

The BEC system that makes it easy even for beginners to lighten the vehicle by means of a shared power supply is already well known. The unique
Futaba
ASP
system
is
built
into
the
BF
series
was
completed by
advancing this BEC system one more step and pursuing greater safety.
ASP detects a drop in the voltage and moves the throttle servo automatically to the drive motor off position which is preset at the transmitter
before steering control is lost by a drop in the Nicd battery voltage while
the vehicle is running. It is also the world's first revolutionary system that
allows steering operation with the remaining power.
(Patent pending)
•ASP setting (NEW ATTACK-BFR only)
Before running, set ASP to the controller stop posi-
tion.
• If the controller is not set to the stop position, when the
running Nicd battery voltage drops, the throttle servo
may stop at a position other than the stop position and
the vehicle may run wild because the throttle servo cannot be controlled from the transmitter.

and check the steering and throttle operations.

When the ASP operates and the vehicle

•If
something gets caught in the gears or the

operate immediately.
•Since the Futaba and FP-R102GF receivers
have the BEC system built into them,
a diode and regulator are not connected.
(Running Nicd battery trouble)
•When the Nicd battery is charged insufficiently or is old, ASP will operate.

(Motor trouble)
•When a modified motor, high power motor,
or a motor whose angle cannot be adjusted
