Functions
End point adjuster/EPA
Use this when performing left and right steering angle adjustments, throttle high side/
brake side operation amount adjustment, and channel 3 servo up side/down side op-
eration amount adjustment during linkage.
- Corrects the maximum steering angle and left and right steering angles when there
is a difference in the turning radius due to the characteristics, etc. 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 adjusted.
- Sub trim (all channels)
- Throttle Acceleration (Brake side)
- Brake mixing rate
- Program mixing slave side (all channels)
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
Make sure that the knuckle stopper is not contacted
during steering operation and that unreasonable
force is not applied to the servo during other channel
operation.
If unreasonable force is applied to the servo horn at the knuckle stopper
during steering operation, the servo may malfunction and the model may
run out of control.
Decide the EPA value
at the contact point.
Caution!
Be sure that the steering
servo does not bind.
