Programming examples - Using flight phases
Using flight phases
Up to 7 different flight phases (flight conditions) can
be programmed with settings independent of one
another within each the model memory.
Each of these flight phases can be called with a
switch or a switch combination. This makes it pos-
sible to program different settings for various flight
states, such as «Normal», «Thermal», «Speed»,
«Distance», etc., then make in-flight changeovers in
a most convenient manner. However, with the flight
phase programming you can also make slight modifi-
cations, e. g. of mixers, to try out by switching during
the flight in order to find the optimal settings for each
model more easily.
However, as owner of an
mc-20 HoTT, or an mc-
16 HoTT with the »Stick mode« option unlocked,
you really should think about the use of flight phases
even before you start the actual programming pro-
cedure, and consider whether you wish to be able to
adjust the digital trims for aileron, elevator and rudder
separately in each flight phase – this is the default
“PH(ase)” setting – or whether you want them to take
effect in all flight phases – the alternative “GL(obal)”
setting.
If you decide in favor of a phase-specific trimming of
the rudder, for example, switch the menu …
»Stick mode« (page 114)
… and change the standard “GL(obal)” default ac-
cordingly.
The same applies for the number of trimming steps in
the “Tr” column:

Control of the electric motor is accomplished, in-
dependent of the C1 stick, with one of the two side
proportional rotary controls or one of the two stand-
ard 3-way switches mounted into the switch panels.
The motor’s speed control is connected to receiver
output 8 as described on page 288 and continued
in Examples 1 and 2. This is why “none” was se-
lected 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 but also
allows all options to be available without restriction in
the “Brake settings” sub-menu of the »Wing mixers«
menu.

Initially, one or more multiple flight phases are pro-
vided with a specific identification (“Name”) for the
respective flight status. This identification has no influ-
ence on the programming of the transmitter; it only
serves for an improved differentiation of the individual
flight phases and is shown later in all flight-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 buttons.

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

… a “blend-in” time can be established for the time in
which a changeover from any other flight phase into
this given flight-phase is to be accomplished in order
to permit a “smooth” transition for different servo posi-
tions. Thus, an increased stress of the model under
certain circumstances with a “hard” change of rud-
der or flap positions, for example, is prevented. The
“Status” column shows you the currently active flight
phase with an asterisk “”.
