Warning
End Point Adjuster "END POINT" (EPA) (All channel)
Use this when performing left and right end point adjustments, throttle high side/
brake side operation amount adjustment, channel 3 and channel 4 servo up side/
down side operation amount adjustment during linkage.
- Correct the maximum steering angle for left and right steering angles when there
is a difference in the turning radius due to the characteristics, etc. of the vehicle.
The EPA function basically determines the maximum steering angle of each channel.
The functions shown below may have been adjusted or the operating range set by EPA
function may be exceeded. Check the linkage each time the following functions are
adjusted.
- Sub trim (all channels) .................................. P53
- Program mixing slave side (all channels) .....P78
- Idle up (throttle) ............................................ P89
- Throttle off, Engine cut (throttle).................. P91
- Throttle acceration (throttle)......................... P65
Maximum steering angle
ATL trim allows adjustment of the brake side operation amount during operation.
Therefore, when the operating angle is adjusted with throttle EPA, ATL trim must also
be taken into account.
ATL trim
End Point Adjuster "END POINT"
Operate each servo over its full stroke and be sure
the linkage does not bind or is not loose.
The continuous application of excessive force to a servo may
cause damage and excessive battery drain.
Adjust the throttle servo so that excessive force is not applied when the engine carburetor is fully
open, fully closed, and the brakes are applied fully.
If the brakes overheat while running, their ability to function properly decreases. Before running,
adjust the suitable maximum servo travel so that excessive force is not applied even when the servo
travel is increased while running.
Adjust the steering servo so that excessive
force is not applied to the servo by the chas-
sis at maximum servo travel.
Decide the EPA value at the
contact point.
Caution!
A whining noise indicates that the
steering servo is improperly set.

Fail Safe Function "FAIL SAFE" (All channel)
Fail Safe Mode (F/S)
This function moves each servo to a preset position when the receiver does not receive a
clear signal from the transmitter.
-When the condition set at "FHSS" is Rx type, fail safe (F/S) can be set only for throttle (TH). Other channels are set to the
normal mode.
-The fail safe data is transferred from the transmitter to the receiver 10 seconds after the transmitter power is turned on. The

ceiver power is turned on next and the data is transferred for approximately 10 seconds after the receiver power is turned on.
-For gasoline engine cars, for safety we recommend that this fail safe function be used to set the throttle channel in the direc-
tion in which the brakes are applied.
Hold mode (HOLD)
This function holds the servo/s at the position they were in immediately before recep-
tion was lost. This applies to the T-FHSS type (R304SB...,etc.) and the S-FHSS type
(R2104GF...,etc.) receivers only. When the receiver used is an R603GF/2004GF or other
FHSS type, this function is not available.
Off mode (OFF)
In this model the receiver stops outputting a signal to the servos if the transmitter signal
is lost. The servos become effectively unpowered.
The F/S, HOLD, and OFF modes are automatically reset when signals from the trans-
mitter can be received again.
Battery fail safe function (BFS)
If the receiver battery voltage drops below a certain value when this function is enabled,
the throttle servo moves to the position set by fail safe function. When the battery volt-
age recovers, the battery fail safe function is automatically reset.
-This function cannot be used when the throttle (TH) is not set to fail safe (F/S).
-This function is for the T-FHSS type (R304SB...,etc.) and the S-FHSS type (R2104GF...,etc.) receiver only. It cannot be used
with the R603GF and R2004FG and other FHSS type.

-Throttle servo (ESC) operation is slowed when the throttle
stick is pushed forward so that the wheels will not spin
even if the throttle is opened faster than required.
This function is not active when the stick is pulled back for

Operation

Speed)
Sudden throttle stick operation on a slippery
surface will cause the wheels to spin, resulting
in poor acceleration. Setting the throttle speed
function reduces wasteful battery consumption
while at the same time enabling smooth, enjoy-
able operation.

Operation
Throttle Acceleration "TH ACCEL" (Throttle system)
The throttle servo will "jump" to a preset position at its maximum possible speed. Un-
like exponential, which adjusts the whole throttle movement into a curve, throttle ac-
celeration simply "jumps" away from neutral and then leaves the remaining response
linear.
The standard value (100% point) of this setup affects the operation amount set by
throttle EPA function.
Set value

Servo horn
Clearance
For GP cars, the linkage must have a clearance
because one servo controls the engine carbure-
tor and brake. Thus, there is a noticeable time
delay at both the forward and brake sides. Sharp
response comparable to that of electric motor cars
is obtained by reducing this clearance at the trans-
mitter side.

This function is used when the front and rear brakes must be adjusted independently
such as with a 1/5 scale GP car. This mixing uses the 2nd CH for the rear brakes and
the 3rd or 4th CH for the front brakes, or controls the front brakes with the 3rd CH and
4th CH servos, or controls the 2nd CH by independent throttle and controls the rear and
front brakes with the 3rd CH and 4th CH.
-When braking, mixing is applied to 2nd CH 3rd CH, 4th CH.
-3rd CH and 4th CH brake amount, 2nd CH, 3rd CH, and 4th CH brake delay, and 3rd
CH and 4th CH brake ABS can be set.
