Futaba 2NBR - Manual (Page 9)

The BEC system that makes it easy even for beginners to lighten the ve-
hicle by means of a shared power supply is already well known. The uni-
que 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 automati-
cally 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 can-
not be controlled from the transmitter.

Since the stop position
differs with the chassis
manufacturer, check it
when connecting the
linkage.

1. Set the transmitter and receiver power switches to on
and check the steering and throttle operations.
2. a) Set the ASP setting switch to the SET side. ASP setting
b) Turn the ASP setting trimmer at the left side of the trimmer
switch with a little screwdriver.
c) Since this moves the throttle servo, set so that it
stops at the stop position of the connected control-
ler.

switch to the NORM side. (If the switch is not switched
to the NORM side, the throttle servo will not be cont-
rolled by the throttle stick.)

• When the Nicd battery voltage drops, the throttle servo is moved to the preset position and the drive motor is stopped
automatically.
