D) Setting The Maximum End Position (Epa) Of The Servo - ModelCraft 23 10 21 Bedienungsanleitung

d) Setting the maximum end position (EPA) of the servo

As opposed to the dual rate function, where the setting of the rotation angles always refers
to both directions of the servo lever movement, the EPA (end point adjustment) allows a
precise individual setting of the maximum admissible rotation angle for the steering, throttle
or the additional servo on each side.
This function is usually used for protecting servos from hitting obstacles even in the maximum
end position (protection of the servo against damage and reduction of power consumption in
the servo).
A value between 5% and 120% can be set. The smaller the value, the shorter the servo angle
on the respective side.
Now set the maximum possible end position in this menu for the steering (CH1) without the
steering servo hitting anything and starting to hum. If a smaller angle should be necessary in
later operation it can then be reduced with the dual rate function.
Should you use an electronic speed control for the speed function (CH2), you can also set a
maximum control value. In order to use the maximum engine speed, however, you should not
set less than 100% in either direction.
If, at a later point in time, you want to make the model slower, for example for a beginner, you
can reduce the value for full speed by means of the EPA function without influencing the
braking function in the electronic speed control.
Our tip:
Simply set these parameters with a separate model memory. Then you only have
to switch to the model memory and your model is ready for a beginner or an
inexperienced driver.
Before you limit the angles in the EPA function, you should check whether for the
dual rate setting (see paragraph "Setting the dual rate function") the default set-
ting of 100% is still set.
Try to design the servo linkage in such a way that you can use EPA settings of 100-
120%.
