FUTABA 4PK-2.4G SuperR Instruction Manual page 73

Fail Safe Unit
When the T4PKSR is used with the Futaba fail safe unit (FSU-1), it will operate as de-
scribed 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.
Example of A.B.S. function setting when BLS351 / BLS352 used
(There will be a slight difference depending on the state of the linkage.)
- Basic setting
ABP : Approx. 30% (If this value is too high, the braking distance will increase.)
CYC : 5~7
DTY : 0 (When grip is low: - side, when grip is high: + side)
DLY : 10~15%
TGP : Approx. 70%
STM : OFF
- When the wheels lock, or the car spins, when the brakes are applied fully
ABP : Increase from 30%
DTY : Shift from 0 to - side (-1, -2, -3)
DLY : Reduce the delay
- When the braking effect is poor and the braking distance is long when the brakes are
applied fully
ABP : Decrease from 30%
DTY : Shift from 0 to + side (+1, +2, +3)
DLY : Increase the delay
1/5 scale car and other independent brakes and ABS
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 74. For more
information, read the brake mixing (BRAKE) item.
