Functions

A.B.S. Function

When the brakes are applied while cornering with a 4 Wheel

Drive or other type of vehicle, understeer may occur. The

generation of understeer can be eliminated and corners can

be smoothly cleared by using this function.

Operation

- When the brakes are applied, the throttle servo will pulse

intermittently. This will have the same effect as pumping

the brakes in a full size car.

- The brake return amount, pumping cycle, and brake duty

can be adjusted.

- The region over which the ABS is effective can be set ac-

cording to the steering operation. (Mixing function)

Without A.B.S.

With A.B.S.

Switch Setting

The A.B.S. function ON/OFF switch can be set with the function select switch func-

tion. (See page 82) SW1 or SW2 can be selected.

Dial / Trim Setting

The brake return amount (ABP), delay amount (DLY) and cycle (CYC) can be con-

trolled with button trim BT1, BT2 or digital trim DT3, etc. with the function select

dial function. (See page 80)

Operation Display

When the A.B.S. function is activated, the LED flashes.

Fail Safe Unit

When the 3VCS is used with the Futaba fail safe unit (FSU-1), it will operate as

described below.

- When the FSU-1 is connected to the throttle channel, and the A.B.S. function has

been activated, the FSU-1 LED will flash each time the servo operates. The reason

for this is that the FSU-1 responds to sudden data changes caused by A.B.S. function

pumping operation. It does not mean that the fail safe function is activated. The servo

will not be affected.

Boat Mode

If "BOAT" is set in the Throttle Mode Function (See page 99), the A.B.S Func-

tion will not work even if you set the A.B.S Function.
