Flight phase-specifi c mixers for collective pitch, throttle and tail rotor

In the “Basic settings” menu a method of switching 
fl ight phases can be activated by assigning the appropri-
ate switches to “Phase 2” and / or “Auto-rotation”. You 
can then switch between the phases “normal” and a 
second phase - to which you can assign a more ap-
propriate name yourself, if necessary - using one of the 
non-centring switches SW 3 … 7; a further switch then 
selects “Auto-rotation”. However, auto-rotation always 
has precedence over the other two phases; see 
pages 68 / 69.
If you have not yet assigned switches for the fl ight 
phases, you should do so now. Use the arrow buttons of 
the left-hand four-way button to move to the right-hand 
column, marked by the switch 

 symbol at the bottom 

of the screen, then press the central 

 button of the 

right-hand four-way button. The switches are assigned 
as described on page 39:

Phase 1 always bears the designation “normal”. Both 
the number and name of this phase are permanently 
assigned, and cannot be altered. For this reason the 
“normal” phase is not stated as Phase 1 in the “Basic 
settings” menu; it is simply concealed.
By default “Phase 2” is assigned the phase name “hov-
er”, but you can change these at any time if you prefer: 
press the central 

 button with the right-hand four-

way button, and use the arrow buttons of the right-hand 
four-way button to select one of the following names:

Five-point curves are available for setting up the control 
characteristics of “collective pitch”, “Ch 1 

¼ throttle” and 

“Ch 1 

¼ tail rotor”. Using these curves it is possible to 

program non-linear mixer ratios along the travel of the 
transmitter stick for these mixers. Move to the display 
page for setting 5-point curves by pressing the central 

 button of the right-hand four-way button (see 

below).
In contrast, the mixers “Ch 1 

¼ throttle” and “Ch 1 ¼ 

tail rotor” are not required for the “Auto-rotation” fl ight 
phase (described in the section starting on page 104); 
instead they are automatically switched to a (user-varia-
ble) pre-defi ned value.
A value must be entered in the “Gyro” line: press the 
central 

 button of the right-hand four-way button, 

then enter a value in the highlighted fi eld using the arrow 
buttons of the right-hand four-way button - in a similar 
fashion to changing the transmitter centre position or 
the offset position with other radio control systems. This 
set-up facility is rounded off with the “Swashplate limit” 
option: this restricts the maximum travel of the swash-
plate servos to the value you set, in the form of a limiter. 
All these options are required for the basic process of 
setting up a model helicopter.
Altered parameters can be reset to the corresponding 
default values at any time by simultaneously pressing 
the 

cd or ef buttons of the right-hand four-way 

button (CLEAR).
The name of the currently selected fl ight phase is 
displayed in the “Helicopter mixers” menu as well as 
in the transmitter’s basic display; this is designed to 
ensure that any changes you make actually apply to 
the appropriate fl ight phase. Note that the servos do not 
change from one setting to another abruptly; they move 
smoothly with a transition time of around one second. 
This does not apply to auto-rotation: when you switch 
INTO auto-rotation, the change takes place immediately.
If you operate the switch selected for a particular fl ight 
phase, the associated fl ight phase is superimposed at 
the left-hand bottom edge of the screen, e. g. “normal”.
