90 Detail program description - Base setup models | Winged models
A speed controller or throttle servo will only take on
this preset position when a certain servo position
or threshold is underrun and a switch is activated.
This is done by setting the desired servo position
(threshold value) into the middle column fi eld,
directly over the column label STO, then selecting
the appropriate ON/OFF switch function in the right
column.
If the percentage value specifi ed for the middle •
column is greater than the current servo position,
i.e. the current servo position lies below the
threshold, the switchover will occur as soon as the
switch is put into its ON position.
If the percentage value specifi ed for the middle •
column is less than the current servo position, i.e.
the current servo position is above the threshold,
the speed controller will initially reduce motor
speed or close the carburetor's throttle servo
only to the extent dictated by the value in the
left column as soon as the servo's position once
underruns the threshold (max. +150 %) after the
switch is changed over to its ON position.
The speed controller or throttle servo will remain in
this cut-off position only until the selected switch is
again changed over followed by a one-time throttle
servo or speed controller movement beyond the
preset threshold with the throttle/brake joystick
control.
The factory setting for the left column is -100 % for
the throttle servo "cut-off" position and a threshold of
+150 % servo position setting in the middle column.

Programming procedure
To change the throttle servo's preset "cut-off" position,
tap on the center
SET key of the right touch pad. The
current setting will be displayed in inverse video. Now
use the selection keys of the left or right touch pad to
set a value at which the motor is reliably "off" without
a startup of the throttle servo. For example -125 %:

The – upper – preset value in the middle column
ensures the motor can be stopped, throughout the
maximum possible positioning range of the servo or
speed controller, alone by the switch to be assigned
in the right column.
However, if a lower threshold is preferred, at which
an underrun will cause the throttle servo or speed
controller with closed switch to enter the throttle cut-
off position for a closed switch condition – by default
the right-side proportional rotary slider – put the
throttle/pitch joystick into the desired position then tap
on the center
SET key of the right touch pad.

Finally, use the column at the right to specify a
switch with which you can cut off the motor directly
(emergency) or which will be activated by the
threshold.

Notes:
Be sure the throttle servo does not run out •
mechanically when the cut-off function is
activated.
A threshold over +100 % is reached by •
temporarily increasing the travel for servo 1 in the
»Servo adjustment« menu to over 100 % then,
after storing the threshold, change servo travel
back to the original value.
