Using fl ight phases
Up to 8 different fl ight phases (fl ight conditions) can
be programmed with settings independent of one
another within each the model memory.
Each of these fl ight phases can be called with
a switch or a switch combination. This makes it
possible to program different settings for various fl ight
states, such as «Normal», «Thermal», «Speed»,
«Distance», etc., then make in-fl ight changeovers
in a most convenient manner. However, with the
fl ight phase programming you can also make slight
modifi cations, e.g. of mixers, to try out by switching
during the fl ight in order to fi nd the optimal settings
for each model more easily.
Before actual programming of fl ight phases can
begin, consideration should be given to whether
the digital trimming of transverse, altitude and side
should be "GL(obal)" – in other words, applicable to all
fl ight phases – or per "PH(ase)" – in other words, each
fl ight phase individually variable.
If you decide in favor of a phase-specifi c trimming of
the elevator, for example, switch the menu ...
»Stick mode«
... and change the standard "global" default accordingly.
The same applies for the number of trimming steps in
the "Tr. step" column:

Control of the electric motor is accomplished,
independent of the C1 joystick, with one of the two
side proportional rotary controls or one of the two
standard 3-way switches mounted into the switch
panels. The motor's speed control is connected to
receiver output 8 as described on page 276 and
continued in Examples 1 and 2 This is why "none"
was selected for the "Motor on C1" line in the »Model
type« menu. This not only causes the column "Motor"
in the »Phase settings« menu to be unavailable
(page 104)
but also allows all options to be available without
restriction in the "Brake settings" sub-menu of the
»Wing mixers« menu.

Name
Initially, one or multiple fl ight phases are provided
with a specifi c identifi cation ("Name") for the
respective fl ight status. This identifi cation has no
infl uence on the programming of the transmitter; it
only serves for an improved differentiation of the
individual fl ight phases and is shown later in all fl ight-
phase dependent menus and in the base screen.
The selection of the respective line, a name and the
setting of the switchover time is done in the "usual"
manner, with a tap on the appropriate key(s) of the
two four-way touch pads.

Note:
With the exception of Phase 1, which should always
be assigned with the name "Normal" since it is
always active, if the fl ight phases are deactivated, it
is completely irrelevant which name is assigned to
which phase!
In everyday use by a model pilot, three to a maximum
of four fl ight phases are usually completely suffi cient:
"Start" with the climb settings
"Thermal" for "Flying high",
"Normal" for normal conditions and
"Speed" for high gear.
