Helicopter mixer
… 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 190 onward.) 
These mixers are used for the basic set-up of a 
model helicopter.
For fl ight phase programming, see the menus:
»
Basic settings, model«, page 84
»
Phase settings«, page 146
»
Phase assignment«, page 148
When the switch for a specifi c fl ight phase is 
actuated, then the name of the given fl ight phase, 
e.g. «Normal», will be 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 159 and 192)
An arrow "
¼" 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. "Pitch ax 
¼ Tail 
rot" mixer means, for example, that when the pitch-
axis joystick is actuated, the tail rotor servo must also 
react within the scope of its setting.
Basic programming procedure:
Select the mixer by using the selection keys of the 
1. 
left or right touch pad.
Depending on the mixer involved, the bottom 
display line will show either SEL or the 
¨
 (indicating 
a change to a second page is necessary).
A brief tap on the center 
2. 
SET
 key of the right touch 
pad will permit direct settings for linear mixer 
ratios. Use the selection keys to set the mixer 
ratio.
Otherwise you will need to switch to the second 
screen page where you can set up the appropriate 
curve mixer.
A simultaneous tap on the 
cd or ef keys of 
the right touch pad (CLEAR) will reset a changed 
value in a given active (inverse video) fi eld back to 
0 %.
Another tap on the center 
3. 
SET
 key of the right 
touch pad will complete the entry.
A tap on the center 
4. 
ESC
 key of the left touch pad 
will cause a return to the previous display page.
Description of helicopter mixers
To set collective pitch curves as well as the two 
mixers, "Channel 1 
¼ Throttle" and "Channel 1 ¼
Tail rotor", there are curve mixers 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 with a brief tap 
on the center 
SET
 key of the right touch pad, see 
description 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 selection keys of the left or right touch 
pad to set a mixer value in the value fi eld (inverse 
video).
The settings available are rounded off with the 
"Swashplate limiter" option: This option can be set to 
restrict maximum defl ection of the swashplate servo 
in the sense of a limiter. Together, these settings 
confi gure the basic set-up of the helicopter model. 
In the "Autorotation" fl ight phase as described 
on page 190, however, the mixers "Channel 1 
¼
Throttle" and "Channel 1 
¼ Tail rot" are not needed 
and therefore switched to a confi gurable default 
value.
Changed parameters can be reset to their respective 
default values at any time with a simultaneous tap on 
the
cd or ef keys of the right touch pad (CLEAR).
  Pitch  
(Pitch curve (Channel 1 
¼ Pitch))
If necessary, use the 
cd selection keys of the left or 
right touch pad to move to the "Pitch" line then tap 
briefl y on the center 
SET
 key of the right touch pad.
