After this has been done, use the arrow keys to move
into the column above the switch symbol then assign a
switch to this fi eld, as described on page 52 in section
"Switches, controls and control switches". Preferably the

SW 1 or 9.

Once this activation switch is closed, the fi rst occurrence
of a threshold underrun will cause the program to switch
over to "Autorotation" and then remain independent of
C1 position in this fl ight phase until the activating switch,
in this example SW 9, is again "OFF".
"Auto. C1 Pos." has precedence over all other fl ight-

Cut-off
Within the framework of autorotation settings for the
mx-20 HoTT transmitter's helicopter program, there
are parameters for an emergency "cut off" of the throttle
servo or motor actuator, refer to the programming
proposal on page 286. However, this option is not
available if an idle position is specifi ed in the "Thr
setting AR" line of the "Helicopter mixer" menu
instead of an (emergency) OFF position; for example,
to avoid restarting the motor after every landing during
autorotation practice. In this case it is better to use this
option as a "cut off" rather than as an emergency OFF
solution.
Depending on the "forw./back" choice made for the
"Pitch min" line of the "Heli Type" menu, this motor "cut
off" option can be coupled to a switch for throttling down
a carburetor servo to the cut-off (or idle) position.

This cut-off (or idle) position is specifi ed by the left
column over the "SEL" fi eld and its value is to be
established through trial and error.
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, directly over the "STO"
fi eld then selecting the appropriate ON/OFF switch
function in the right column.

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.
