On the other hand, another marker is located in the
end zone, see display area in the figure below, so you
can reach by clicking once again the original idle set-
ting, see page 62.
The cut-off is only in the latter half of the throttle limit
rotary vane path as idle.
That is, only in this area, the marker line is set and
stored.

For this reason, the label is also hidden, as long as the
throttle limit transmitter is in front of the middle position:

Notes:
•
Since this trim function “from Motor” is ef-
fective only in direction, the display of your
transmitter will change accordingly if the
encoder direction to the collective pitch minimum
position of the C1 stick from “back” - whereupon
the above gures change on “front “menu” heli-
copter type in the line ”pitch min“ . Also replace
the effects shown the page, if you pitch left in the
line change of Pitc right ”control assignment“ of
the menu Basic setting model”.
• Take advantage of the »Servo display« to ob-
serve the inuence of the throttle limit control. The
»Servo display« screen can be reached from al-
most any menu position with a simultaneous tap
on the  selection keys of the left four-way but-
ton, Bear in mind that servo output 6 controls the
throttle servo on the transmitters
mc-16 HoTT
and mc-20 HoTT!
• A servo connected to output 8 or 12 can be used,
independently of this, for other purposes by
means of mixers, provided that this servo is de-
coupled from the operating element specied by
input function “Lim.” via the »Mix only channel«
menu; see page 212.
• The throttle restriction set by the throttle limiter is
shown as a horizontal bar in the throttle curve di-
agram on the second display page of the “C1 
Throttle” option in the »Helicopter mixer« menu
(see page 188). The output signal for the throt-
tle servo cannot be higher than the level set by the
horizontal bar:

The above diagram shows precisely this scena-
rio: in the above example, the throttle limit control
is set to about +20 % and thus restricts the move-
ment of the throttle servo to about +20 % of full
travel.
Time delay for the throttle limiter
To safely prevent the carburettor from opening too rap-
idly, assign the throttle limiter input “Lim.” to a time de-
lay that takes effect only in the direction of full throttle.
This applies especially if the throttle limiter is controlled
by a switch rather than, as preset, with the right-side
proportional rotary slider.
To set a delay time, push the throttle limit control to
its forward limit or move the switch into its full-throttle
position then use the selection keys of the left or right
four-way button to select the “– time +” column:

After a brief tap on the centre SET key of the right
four-way button, the selection keys of the left or right
four-way button can be used to select the desired time
delay, e. g. 5 seconds:

A brief tap on the centre SET key of the right four-way
button or the ESC key of the left four-way button will
complete the entry.
