Detail program description - Control adjust
the – digital – C1 trim. You should thus (initially) leave this 
value at +100%.
Furthermore, this variable "limiting" of throttle travel not 
only gives you a convenient method for starting and 
stopping the motor, but may also prove to have added 
a not inconsiderable increase in safety! For example, 
just imagine what could happen if you were carrying the 
helicopter to the take-off site with the motor running and 
you accidentally moved the C1 stick … 
Accordingly, if the carburetor or speed controller is open 
too far, an audible warning is heard as soon as you turn 
on the transmitter, and the message below is shown on 
the basic display:
Throttle
too
high !
Tip:
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!
   Basic  idle  setting
Start by turning the throttle limiter – by default the 
CTRL 6 proportional rotary control on the top left of the 
transmitter – clockwise as far as it will go. Set the throttle/
collective pitch stick to the maximum pitch position and 
also check the submenu "C1 
 Thr" on the menu …
"Helicopter mixers" 
(pages 164 … 179)
… to ensure you have an active standard throttle curve. 
If, for example, the standard throttle curve has already 
been changed following the initialization of a model 
memory, then this must be reset at least temporarily to 
the values "Point 1 = -100%", "Point 3 = 0%" and "Point 
5 = +100%":

Note:
As the throttle trim lever has no effect if the throttle 
limiter is open, its position here is unimportant.
Now – without starting the glow motor – adjust the 
throttle servo, preferably mechanically and optionally 
using the servo 6 travel adjustment option in the 
"Servo adjustments" menu, so that the carburetor is 
completely open. 
Now, close the throttle limiter completely by turning the 
CTRL 6 proportional rotary control in an anti-clockwise 
direction as far as it will go. Use the trim lever on the 
throttle/collective pitch stick to move the trim position 
marker to the "Motor OFF" position – see the fi gure in 
the next column.
Note:
In contrast, when the throttle limiter is closed, 
the position of the throttle/collective pitch stick is 
meaningless. It can therefore remain at the maximum 
collective pitch position so that, when adjusting 
carburetor linkages, the throttle limiter alone can be 
used to switch between full throttle (throttle limiter open) 
and "Motor OFF" (throttle limiter closed).
Now, with the throttle limiter closed, adjust the 
carburetor linkages so that the carburetor is (just) 
completely closed. Take extreme care to ensure that the 
throttle servo cannot travel mechanically to either of the 
two extreme positions (full thr./Motor OFF).
To complete this basic confi guration, the idle trim 
adjustment range must now be matched against point 
"L" on the throttle curve. To do so, set point "L" for the 
mixer "C1 
 Thr" on the "Helicopter mixers" menu 
from about -65% to -70%:

To confi gure a smooth transition from the idle trim to the 
throttle curve exactly, the collective pitch stick should 
be moved to and fro slightly at its minimum position with 
the throttle limiter closed and the idle trim fully open. 
The throttle servo must not move as well! Any further 
adjustments to the throttle curve must of course be 
made later in fl ight.
The motor is always started with the throttle limiter fully 
closed, whereby idle is set exclusively by using the trim 
lever of the throttle/collective pitch stick. 
Throttle limit in conjunction with digital trim
In conjunction with the CTRL 6 throttle limit rotary 
control, the C1 trim sets a marker (
) in the motor's 
confi gured idle position, from which the motor can be 
switched off via the trim. If, on the other hand, a further
