marker is located at the end-point (see the partial 
display screenshot shown below), then you can simply 
click once to restore the original idle confi guration (see 
also page 54).
This switch-off trim functions as an idle trim only in the 
left half 
of the throttle limit rotary control's path. That 
is: only within this range is the marker line set and also 
stored.

Notes:
Since this trim function only takes effect in the 
• 
"Motor OFF" direction, the screen image shown 
above changes appropriately if you alter the control 
direction for the pitch minimum position of the C1 
stick from "back" (as shown in the above image) to 
"forward" in the "min. pitch" line on the menu "Base 
setup model"
. The effects as shown also swap to 
the other side if you swap pitch right (as shown in the 
above screen images) to pitch left in the "Stick mode" 
line on the "Base setup model" menu (see page 74).
You can use the 
• 
"Servo display" menu to observe 
the infl uence of the throttle limit slider. This menu 
can be accessed from almost any other menu by 
simultaneously pressing the 
 keys on the left 
touch pad. Bear in mind that servo output 6 controls 
the throttle servo on the mx-20 HoTT!
A servo connected to output 12 can be used 
• 
independently of this for other purposes by means of 
mixers, provided that you separate the servo from the 
transmitter control at function input 12 on the "MIX-
only channel
" menu; see page 193.
The throttle restriction set by the throttle limiter 
• 
is shown as a horizontal bar in the throttle curve 
diagram on the second display page of the "Channel 
 Throttle" option on the "Helicopter mixers
menu (see page 168). The output signal for the 
throttle servo cannot be higher than the level set by 
the horizontal bar:

The above diagram shows precisely this scenario: in 
the above example, the throttle limit control is set to 
-60% and thus restricts the movement of the throttle 
servo to -60% of full travel.
 Time delay for the throttle limiter
To safely avoid the carburetor opening too rapidly, you 
should assign throttle limiter input 12 a time delay that 
takes effect only in the direction of full throttle. This 
applies especially if you are controlling the throttle limiter 
using a switch and not the default CTRL 6 proportional 
rotary control.
To set a delay time, proceed as follows: turn the throttle 
limit control as far to the right as it will go or move the 
relevant switch to the full-throttle position; then use the 
arrow keys on the left or right touch pad to select the 
"–time+" column:
