18.9 ELEVATOR -> SPOILER (FLAP) MIXER
This menu is used for setting up a mixer which causes all the
wing flaps to be lowered or raised to change the wing camber
when an elevator command is given. This amplifies the eleva-
tor effect, and enables the aircraft to turn more tightly and per-
form “square” manoeuvres.
A mixer curve can be programmed for this function, and it can
be activated using a switch which you can select. As with
many functions, it is also possible to determine whether the
settings are to apply to all flight modes (Glob) or only to the
currently activated flight mode (Sepa). You can define an auxi-
liary transmitter control which is used to fine-tune the function.
Mark the button field of this mixer in the Model menu. The
screen now looks like this:
The first step is to activate this mixer function in the Status
line. Mark the field, and the same field then displays ‘ON’ or
‘OFF’ instead of ‘INA’ (inactive), according to the position of
the switch.
The effects and method of setting the ‘Glob’ or ‘Sepa’ mode
have already been described; the function is programmed
using the appropriate switch field.
A switch can be defined to trigger the mixer, using the stan-
dard procedure: mark the appropriate field and define the des-
ired switch and its direction of operation in the switch select
menu which now appears. The default setting is ‘NONE’,
which means that the mixer is permanently switched on.
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).
• Selecting the fine-tuning settings
It is possible to program a transmitter control which is used
to carry out fine adjustments (fine-tuning) of the mixer set-
tings. Changes are entered in the ‘Fine-tuning’ frame. Mark
the appropriate field and select your preferred transmitter
control in the transmitter control / switch select menu which
then appears. The default is ‘NONE’. Any of the auxiliary
transmitter controls can be used. Your selected control is
displayed 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 pre-defined 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.
• Programming a curve
A curve can be programmed to define the effect of the Ele-
vator -> flap mixer. In addition to selecting a curve type for
each side (Rate A and Rate B), you can also enter a percen-
tage value. The values are adjusted exactly as described for
programming the Dual Rate curves. Please refer to this in
Section 17.2 on page 58.
The actual settings for the travels of the (max.) four aileron
servos and four flap servos are entered in a separate sub-
menu (see screen shot below).
For each servo the servo travels can be entered separately
for each side of centre in the form of percentage values.
The values are set using the familiar method: mark the field,
confirm it, then set the percentage value using the arrow
buttons.
The screen shot shows a typical example of programming
for this sub-menu.
NOTE:
If you have selected a flying wing in the ‘Model type’ base
menu, two winglets will also appear in the set-up window
for this mixer. Please enter appropriate values at this point if
required.
As a basic rule, please note that the programming options
and the actual appearance of the screen display may vary
slightly according to the model type and wing type you
have selected.
