18.5 AILERON -> RUDDER MIXER
This menu is
used for setting
up a mixer
which causes
the rudder (and
the winglet rud-
ders, if present)
to move in the
same direction
when an aileron
command is
given.
When this func-
tion is activated,
the ailerons and
rudder(s) are coupled, so that only one stick has to be opera-
ted in order to turn the model. This function is particularly use-
ful for controlling large-scale model aeroplanes, as it elimina-
tes adverse yaw completely when set up correctly.
It is possible to set up a curve in order to obtain the exact
mixer rates. The function can be activated using a switch
which you can select. As with many functions, it is also possi-
ble to determine whether the settings are to apply to all flight
modes (Glob) or only to the currently activated flight mode
(Sepa). An auxiliary transmitter control can be assigned to the
function for fine-tuning.
Mark the ‘Aileron -> rudder’ mixer in the Model menu. The
screen now looks like this:
• Activating the mixer / defining the status
The function must first be activated, as previously descri-
bed. You can now set the ‘Glob’ or ‘Sepa’ mode in the cus-
tomary manner.
• Defining the switch
A switch can be defined for triggering the mixer; it is set up
in the usual way: simply mark the corresponding field and
define the switch you wish to use and its direction of opera-
tion in the switch select menu which then appears.
• Selecting the display type
You can now select your preferred display mode in the ‘Dis-
play’ field: the alternatives are to show all flight modes (All
modes), the currently active mode (Separate) or the fine-
tuning display (Fine).
• Programming a curve
A curve can be programmed to define the effect of the
Aileron -> rudder mixer. In addition to selecting the curve
type for each side (Rate A and Rate B), you can also enter a
percentage value. The settings are adjusted exactly as des-
cribed for programming the Dual Rate curves. Please refer
to this in Section 17.2 on page 58.
• Selecting the fine-tuning settings
It is possible to assign a switch or other transmitter control
to the task of fine-tuning aileron differential; this is carried
out in the ‘Fine tuning’ frame. Mark this field, and the trans-
mitter control / switch select menu appears; now you can
select the transmitter control you wish to use for this pur-
pose. The default setting is ‘NONE’. Any of the auxiliary
transmitter controls can be selected. Your selection is dis-
played in the field.
The next step is to define the operating mode for the trans-
mitter control you have chosen; this is carried out using the
now familiar procedure: mark the field containing the sym-
bol for the effect of the transmitter control; the effect mode
changes each time you mark the field. You can choose from
a total of four modes, whose function is displayed in sche-
matic form on-screen. The meaning of the symbols and the
different modes is explained in the description on page 61.
Once you have selected a transmitter control for fine-
tuning, and programmed your preferred mode, you should
determine the effect range for the fine-tuning procedure.
The first step here is to mark the right field in the ‘Fine-
tuning’ frame. The arrow buttons now appear at the right
margin of the screen, and they are used to enter the effect
range as a percentage figure; the set value is displayed in
the appropriate field. The direction of effect can be reversed
if necessary by altering the prefix in the central field.
If you now operate the selected transmitter control, the
function is adjusted within the predefined range. The value
currently set is displayed in brackets below the field. At the
same time, a fine line is superimposed on the programmed
curve to indicate the alteration effected by the fine-tuning
process.
