A.B.S Function "A.B.S"
When the T4PL is used with the Futaba fail safe unit (FSU-1), it will operate as de-
scribed below. However, FSU-1 cannot be used at the high speed mode.
- 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.
Fail Safe Unit
- Basic setting
AB.P: Approx. 30% (If this value is too high, the braking distance will increase.)
CYCL: 5~7
DUTY: (When grip is low: LOW side, when grip is high: HIGH side)
DELY: 10~15%
TG.P: Approx. 70%
- When the wheels lock, or the car spins, when the brakes are applied fully
AB.P: Increase from 30%
DUTY: Shift to "LOW" side
DELY: Reduce the delay
- When the braking effect is poor and the braking distance is long when the brakes are
applied fully
AB.P: Decrease from 30%
DUTY: Shift to "HIGH" side
DELY: Increase the delay

(There will be a slight difference depending on the state of the linkage.)
ABS can be independently set for the brakes which are controlled by the 3rd CH and
4th CH by using the brake mixing (BRAKE) function described on page 72. For more
information, read the brake mixing (BRAKE) item.
