In addition to the generally interesting adjustment
of the increments in the column St" (number of trim
increments for each "Trim lever click") of the digital
trimming – separately adjustable for each of the four
trim levers – in the case of the (later) programming of
fl ight phases in the second column of this menu you can
select whether the trimming of transverse, altitude and
side should work "globally" in equal measure over all
fl ight phases or separately in each (fl ight) "phase".
The "Time" column, on the other hand, is not of interest
for this initial programming.
With the previous settings, you can basically fl y winged
and motor models – the latter if you have set the idle
joystick direction correctly in the "Motor at C1" of
the
"Model type" . However, the "fi ne-tuning" is still
missing. The fi ne-tuning certainly adds to the enjoyment
of fl ying over the course of time. Therefore, if you can
already fl y your model safely, you should delve into the
menu…
"Wing mixer" (page 146 … 163)
… where various options are available depending on the
specifi cations made in the
"Model type" menu, page 82.
Since in this section we are dealing with a model
with only two servos in the wings, the Multi-fl ap menu
beginning on page 157 is not shown.

If this display appears, you model is equipped with
a motor, contrary to the assumption of this section,
and therefore you have selected "front/rear" instead
of "none" in the line "Motor to C1" of the "
Model
type " menu, page 82. Therefore, change this setting
temporarily or change the "yes" entry in the "Motor"
column of the " Phase setting " menu, page 128 to "no"
for the currently active fl ight phase
– Phase 1 in this
case.

After this statement about mutual dependencies, back
to the topic:
If the ailerons should be elevated for braking, an
appropriate value is then entered in the "
Crow " line
after activation of the value fi eld of the "AILE" column.
In addition, a value should always be entered in the
line below it, "
D.red. " (differentiation reduction), which
corresponds to the value you entered or would like to
enter on the fi rst page of the "
Wing mixers " menu in
the line "Aile.diff." (see fi gure above)! With this entry,
on actuation of the brake joystick, the set aileron
differentiation is hidden again proportionally in order to
increase the downward the throw of the raised ailerons
and thus signifi cantly improve its effect in the braking
phase.
A setting of the "
Elevat curve " mixer is then only
necessary if the fl ight speed of the model changes too
dramatically on actuation of the brake system. In any
case, you should try out the setting at a suffi cient and
readjust, if necessary, whereby you should focus less
on the fl ight position than on maintaining the "normal"
fl ight speed of the model. Otherwise there is the risk that
the model plunges when engaging the brake system,
because it became too slow in the meantime:
