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.

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 – upper – preset value in the middle column

maximum possible positioning range of the servo or
speed controller, alone by the switch to be assigned
in the right column.

controller with closed switch to enter the throttle cut-
