A range of options are available for positioning
flaps. You can ...
a) ... simply accept one position per flight phase,
by setting only the corresponding trim values.
b) ... vary the flaps positioned by a) with a
transmitter control assigned to "Input 6" in
the »Control adjust« menu, page118,
and if desired by also selecting flight-phase
dependency "PH" in the "Type" column.
The selected transmitter control directly controls
the two flap servos located on receiver outputs
6 and 7 and, as required, also the two FL2
servos connected to outputs 9 and 10 – assuming
that corresponding flaps have been specified
on the "Aileron/camber flaps" line in the
»Model type« menu. This transmitter control
indirectly controls the flap position of the ailerons
via the percentage value entered in the "AILE"
(and "AIL2") column on the "FLAP" line of the
multi-flap menu.
However, in order to improve control sensitivity
for flap settings, travel should be reduced to
about 25 % in "Input 6" line of the »Control
adjust« menu.
c) ... alternatively, you can also leave the default
entry of "0 %" in the "AILE" (and "AIL2") column
on the "FLAP" line of the multi-flap menu, and
use the »Control adjust« menu to assign
both input 6 and input 5 to the same transmitter
control. You can then set the degree to which
both flap pairs are affected, optionally making
this flight phase-dependent by selecting "PH"
in the "Type" column, with the respective travel
adjustment.
Basic programming procedure
1. Select the desired line with the  selection keys
of the left or right touch pad.
Depending on the line selected, the bottom line of
the display will either show the "Next page" icon
() or a switch icon.
2. Depending on the line selected, you will either
switch to the next page – on which you carry out
the same procedure as below – or the desired
value field is activated by tapping the centre
key of the right touch pad.
3. Use the selection keys to set the mixer ratio or
degree of differential.
To configure symmetrical mixer values, move the
transmitter control or stick to its centre position, so
that the marker frame surrounds both value fields. To
configure asymmetric values, move the transmitter
control/stick to the corresponding side.
Negative and positive parameter values are
possible, in order to be able to adjust the
respective function to the direction of servo
rotation or flap orientation.
4. A simultaneous tap on the  or  keys of the
right touch pad (CLEAR) will reset the entry value
in the given active (inverse video) field back to its
default value.
5. Complete the entry with a tap on the centre
key of the left touch pad or the centre
the right touch pad.
Assigning switches
Wing mixers "Aileron 2  4 rudder" and "Flaps 6  3
elevator" can be made optionally on/off switchable by
way of a switch or expanded switch.
Accordingly, when the respective line is selected, the
familiar switch symbol (
edge of the screen.
Switching delays
The delay time or switch time configured on the
»Phase settings« menu, page 142, for the respec-
tive flight phase also affects all wing mixers and thus
avoids abrupt changes to flap configurations when
switching between the flight phases.
SET
Mixer neutral points
For all mixers on the "Brake settings" sub-menu, the
"brake offset" to be set on the »Model type« menu is
to be configured to the transmitter control position at
which the airbrakes are retracted.
Accordingly, in the "Brake offset" line of the »Model
type« menu, see page 94, specify Input 1, 7, 8 or
9 and the offset to accommodate personal piloting
habits. When selecting "input 1", please note also that
you may need to specify your desired "Throttle min"
position "forward/back" before establishing the offset
point in the "Motor at C1" line.
Note:
If the offset is not set right at the end of the
transmitter travel, the rest of the travel is a
"dead zone", i. e. the transmitter control does

key of
sub-menu. Otherwise, the mixer travel is expanded
back to 100 % automatically.
All other mixers in the »Wing mixers« menu have
their neutral point with the control at its centre, i. e.
they have no effect at this control position. The value
set is mixed in at full travel.
