when the servo position first falls below the switching
threshold (max. +150%).
The speed controller or throttle servo remains at
this motor OFF position until you operate the select-
ed switch again, and use the throttle / brake stick to
move the throttle servo or speed controller beyond
the pre-programmed switching threshold.
The default value in the left-hand column for the “motor
OFF” position of the throttle servo is -100%; the default
switching threshold in the centre column is a servo posi-
tion of +150%:

Programming
This is the procedure for changing the default value for
the “motor OFF” position of the throttle servo: briefly
press the central
SET button of the right-hand touch-key:
the current setting is now highlighted (dark background).
Now use the arrow buttons of the left or right-hand
touch-key to enter a value at which the motor is reliably
“off”. If you are controlling a throttle servo (carburettor)
it is important to ensure that the throttle servo does not
strike its mechanical end-stop, e.g. -125%:

The default value in the centre column is deliberately
high, as this enables you to stop the motor over the
maximum possible range of servo travel (or speed con-
troller range) simply by operating the switch; the switch
is assigned in the right-hand column later.
However, if you prefer to set a lower switching threshold,
so that the switch only takes effect when the throttle
servo or speed controller is below a certain point, then
you should reduce the pre-set servo travel from +150%.
This is accomplished by moving the throttle / brake
stick until the throttle servo or speed controller is at the
position you prefer, then briefly pressing the central
SET
button of the right-hand touch-key:
mod name
stick mode

tail type normal

cut off ––– +100%

–125%
The final step is to move to the right-hand column
and assign a switch which you would like to use to cut
the motor (in an emergency) or activate the switching
threshold.

Notes:
You must ensure that the throttle servo does not •
strike its mechanical end-stop when the motor stop
switch is operated.
To set a switching threshold higher than +100%, tem-
•
porarily increase the travel of servo 1 to more than
100% in the “Servo settings” menu, and then restore
the original value once you have stored the switch-
ing threshold.

When you select “tail type” using the arrow buttons
 of the left or right-hand touch-key, you will see
the corresponding input field framed. Touch the central
SET
button of the right-hand touch-key to highlight the
current setting. Now use the arrow buttons of the right-
hand touch-key to select the option which matches your
model:
