18.3 AILERON -> FLAP MIXER
This menu is
used to set the
values for a
mixer which
causes the
spoiler flaps
(inboard flaps)
to move in the
same direction
as the ailerons
when an aileron command is given. This mixer improves the
roll rate of a model glider, because the flaps deflect to support
the ailerons, thereby generating a greater roll moment. At the
same time the induced drag of the wing is reduced when the
model is turning.
The mixer rate can be adjusted in the usual way, but it is also
possible to set up a curve in order to obtain the exact control
surface travel you require. The function can be activated using
a switch which you can select; it can also be connected to
other mixers via a link (Link).
Mark the ‘Aileron ? flap’ mixer in the Model menu. The screen
now looks like this:
Start by activating this function in the ‘Status’ line using the
familiar method, then enter the mixer values for both flaps as
percentages using the arrow buttons in the standard way, in
each case for left and right aileron deflections. If you need to
reverse the direction of travel, this is achieved by changing the
prefix. The effects and method of setting the ‘Glob’ or ‘Sepa’
mode have already been described; the function is pro-
grammed using the appropriate switch field.
The adjustment range for both directions of travel for both
flaps is -120% to +120%; the default setting is 0%.
A switch can be defined to trigger the mixer, using the stan-
dard procedure. Mark the appropriate field, then define the
desired switch and its direction of operation in the switch
select menu which subsequently appears.
If you wish to link this mixer to another mixer, the appropriate
settings should be entered in the ‘Link’ line. You must first acti-
vate this option, then define the mixer to which a link is to be
created.
A mixer curve can also be defined and programmed as already
described several times. An ‘Offset’ and / or an ‘X-offset’ shift
can be implemented in the usual manner.

AILERON -> BRAKE FLAP MIXER
This menu is
used for setting
up a mixer
which causes
the brake flaps
to move in the
same direction
as the ailerons
when an aileron
command is
given. This mixer helps to improve the manoeuvrability of a
model aircraft around the longitudinal (roll) axis, because the
flaps deflect to support the ailerons, thereby generating a gre-
ater roll moment. At the same time the induced drag of the
wing is reduced when the model is turning.
The mixer rate can be adjusted in the usual way, but it is also
possible to set up a curve in order to obtain the exact control
surface travel you require. The function can be activated using
a switch which you can select; it can also be connected to
other mixers via a link (Link).
Mark the ‘Aileron -> brake flap’ mixer in the Model menu. The
screen now looks like this:
Start by activating this function in the ‘Status’ line using the
familiar method, then enter the mixer values for both brake
flaps as percentages using the arrow buttons in the standard
way, in each case for left and right aileron deflections. If you
need to reverse the direction of travel, this is achieved by
changing the prefix. The effects and method of setting the
‘Glob’ or ‘Sepa’ mode have already been described; the func-
tion is programmed using the appropriate switch field.
The adjustment range for both directions of travel for both
brake flaps is -120% to +120%; the default setting is 0%.
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 then appears.
If you wish to link this mixer to another mixer, the appropriate
settings should be entered in the ‘Link’ line. You must first acti-
vate this option, then define the mixer to which a link is to be
created.
A mixer curve can also be defined and programmed as pre-
viously described. An ‘Offset’ and / or an ‘X-offset’ shift can be
implemented in the usual manner.
