106 Detail program description - Joystick setting | Helicopters
Both joysticks are equipped for digital trimming. 
When turning trim wheels, every "click" will shift the 
joystick's neutral position by a certain value. 
The current position is shown on the screen and 
the adjustment is also made "audible" with acoustic 
tones. This makes fi nding the mid-point during fl ight 
easy, without looking at the screen. If the mid-point is 
overrun, a brief motion pause will be inserted.
Current trim values are automatically stored when a 
model memory change is made. 
Furthermore – except for trimming the throttle/brake 
joystick – digital trimming is effective selectively either 
as a global parameter, i.e. consistent in all fl ight 
phases, or as a fl ight-phase specifi c parameter. This 
specifi cation as "Global" or "Phase" is made in the 
»Stick mode« menu described here, whereas throttle 
trimming is always made "global" by software, i.e. 
independent of fl ight phases.
This setting is visualized in the base screen by a 
"shadow" on trim bars:
shadow present = global,
no shadow = fl ight phase dependent.

In the following fi gure, pitch-axis trimming is used as 
an example of fl ight-phase dependence – presented 
at the left in its default Mode 1.

This menu, adapted for helicopter models, permits 
the four digital trim wheels to be set and their trim 
effects to be assigned, selectively, as a "deceleration" 
factor to control functions 1 through 4.
The desired line can be reached by using the 
selection keys of the left or right touch pad. Once the 
appropriate function fi eld has been selected and then 
the center 
SET
 key of the right touch pad is touched 
briefl y, the fi eld will appear in inverse video and the 
desired setting can be made with the selection keys 
of the right touch pad.

These setting variations are confi gured to 
accommodate the needs of helicopter models, which 
is why the following alternative options are available 
for the "Thr." line:
Thr trim
Pitch/thr
Roll
Pitch ax
Tail rot.

"Thr trim": 
(throttle limit)
 
C1 trimming operates as idle trimming 
when the "throttle limit" function 
regulates the motor for starting, see 
»Control adjust« menu, page 117.
"Throttle AR":  (Throttle Autorotation)
 
C1 trim operates as idle trim exclusively 
in the «Autorot» fl ight phase.
 
This makes it possible to assign a 
principle (fi xed) preset AR throttle 
position in the »Helicopter mixer«
menu, page 176, e.g. during 
autorotation practice with the trim 
wheel "varied".
 
A simultaneous tap on the 
cd or ef
keys of the right touch pad (CLEAR)
will reset the option back to "Thr trim".
"Pitch": 
Due to internal coupling, C1 trimming 
acts equally on all pitch servos available 
without infl uencing the throttle servo.
On the other hand, the trim effects of respective 
digital trim controls for the lines "Roll", "Pitch ax" 
and "Tail rot." can be switched over from "Gobal" to 
"Phase" and vice versa.
