… all of the fl ight phase-specifi c helicopter mixers are 
described, with the exception of the mixers for auto-
rotation fl ight (discussed from page 178 onwards.) 
These mixers are used for the basic set-up of a model 
helicopter.
For fl ight phase programming, see the menus:
"
•  Base setup model", page 74
"
•  Phase settings", page 132
"
•  Phase assignment", page 134
When you actuate a switch for a specifi c fl ight phase, 
then the associated fl ight phase, e. g. "Normal", is 
displayed at the lower left edge of the display screen:

In each of these fl ight phases – with the exception of 
the auto-rotation phase – the typical helicopter mixing 
and coupling functions shown in the screen-shot 
above are available for setting up the model helicopter. 
These functions are described in the fi rst part of this 
comprehensive chapter.
General information on mixers, 
(see also pages 145 and 180)
An arrow "
" indicates a mixer. A mixer "branches off" 
the signal fl ow of a control function at a particular point, 
in order to use this fl ow to cause a predetermined effect 
on a further control channel and, ultimately, the receiver 
output. The "Nick 
 Tail" mixer, for example, means 
that the tail rotor servo will be confi gured to follow 
commands from the pitch-axis joystick.
Basic programming procedure:
Select the mixer by using the arrow keys on the left 
1. 
or right touch pad.
Depending on the mixer, the lower line of the display 
will show SEL or the "
" icon, which indicates that 
you need to move to a second page.
The linear mixer ratios can be set directly by briefl y 
2. 
tapping the center 
SET
 key on the right touch pad: 
Use the arrow keys to confi gure the mixer ratio.
Otherwise you will need to switch to the second 
screen page where you can set up the appropriate 
curve mixer.
If you tap the 
 or  keys on the right touch 
pad (CLEAR) at the same time, this will reset values 
changed in the active (highlighted) fi eld back to 0%.
Complete the confi guration by tapping the center 
3. 
SET
 key on the right touch pad again.
You can page back by tapping the center 
4. 
ESC
 key on 
the left touch pad.
Description of helicopter mixers
To confi gure collective pitch curve settings and the two 
mixers "Channel 1 
 Throttle" and "Channel 1  Tail 
rotor", curve mixers are available in all fl ight phases. 
Accordingly, these mixers also permit the programming 
of non-linear mixing ratios along the path of joystick 
travel, if required. Switch to the display screen for curve 
settings by briefl y tapping the center 
SET
 key on the 
right touch pad – see discussion below.
The curve is set up basically in the same way as the 
Channel 1 curve for helicopters, but we will describe 
it again here in detail using pitch confi guration as an 
example, to save you having to leaf through the manual.
In the remaining lines, fi rst activate the value fi eld and 
then use the arrow keys on the left or right touch pad to 
set a mixer value in the value fi eld (now highlighted).
The settings available are rounded off with the "swash 
limiter" option: These option can be confi gured to 
limit the maximum defl ection of the swashplate servo. 
Together, these settings confi gure the basic set-up of 
the helicopter model. 
In the "Autorotation" fl ight phase as described on page 
178, however, the mixers "C1 
 Throttle" and "C1 
 Tail" are not needed and therefore switched to a 
confi gurable default value.
If you want to reset any changed parameters to 
their default values, you can do so at any time by 
simultaneously tapping the 
 or  keys on the 
right touch pad (CLEAR).
  Collective  pitch    (Collective pitch curve (C1 
 Pitch))
If necessary, use the arrow keys 
 on the left or right 
touch pad to move to the "Pitch" line. Now briefl y tap the 
center 
SET
 key on the right touch pad:
