End Point Adjuster "END POINT"

Use this when performing left and right end point adjustments, throttle high side/brake
side operation amount adjustment, or 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 of the vehicle.
Maximum steering angle
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 adjust-
ed.
- Sub trim (all channels) .................................. P51
- Program mixing slave side (all channels) ..... P78
- Idle up (throttle) ............................................ P89
- Throttle off, Engine Cut (throttle)................. P91
- Throttle acceleration (throttle) ...................... P63
ATL trim
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.
Warning
Operate each servo over its full stroke and be sure
the linkage does not bind or is not loose.
The continuous application of unreasonable force to a servo may
cause damage and excessive battery drain.
Adjust the throttle servo so that unreasonable force is not applied when the engine carburetor is ful-
ly 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 unreasonable force is not applied even when the
servo travel is increased while running.

(All channel)
Caution!
A whining noise indicates that the
steering servo is improperly set.
Decide the EPA value at the
contact point.
Adjust the steering servo so that unreason-
able force is not applied to the servo by the
chassis at maximum servo travel.
