End Point Adjuster "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 ad-
justed.
- Sub trim (all channels)
- Program mixing slave side (all channels)
- Tilt mixing (steering, channel 3)
- Idle up (throttle)
- Start Function, Engine Cut (throttle)
- Throttle acceration (throttle)
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
When the steering angle is insufficient even though EPA is increased to maximum
(120%), the steering angle can be increased somewhat by using program mixing.
(Setup example: See page 85.)
Remark
End Point Adjuster "EPA"
ｊ 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 full open, full closed, and
the brakes are applied fully.
Especially, the braking effect becomes poor by heating of the brakes while running. Before running, adjust the suitable
maximum servo travel so that unreasonable force is not applied even when the servo travel is increased while running.
Adjust the steering servo so that unreason-
able force is not applied to the servo by the
chassis at maximum servo travel.
Caution!
