Further adjustments

If you have followed our programming example to this
point, you will have a helicopter which is set up pro-
perly, and is in an ideal state for hovering practice and
simple circuits. Of course, you may wish to activate
additional functions depending on your skill and fl ying
experience.

If you wish to fl y using different rotor speeds and trim
set-ups, you will need to activate a series of “

Flight

phases

” which can be called up via switches which

you assign.

The fi rst step in this process is to call up the menu …

… where the symbols at far right in the “Status” co-
lumn have the following meaning:

“–”: No phase switch present

“+”: Phase switch present

“

”: Currently active phase

Before you set up the fl ight phases you should consi-
der carefully whether you want to use individual swit-
ches to select them, or – always our recommendation
– use one three-position switch which enables you to
select up to three fl ight phases in addition to auto-ro-
tation. The latter option is more logical, and easier to
remember.

In the menu shown above the “

Autorot

” line is alrea-

dy selected. If the auto-rotation phase is activated, it
always has absolute priority over any other phases to
which you assign switches.

In this menu your fi rst step is to assign unambiguous
names to phases 1 to 3; the names are simply se-

lected from a list. The phase name makes it easier to
distinguish the various phases, and is later displayed
on the screen in all phase-specifi c menus, e. g.:

Sw. time

Move to the next column and set the transition time
which you wish to apply when switching FROM one
phase INTO a new one: a setting of about one se-
cond is usually ample. Later this value can also be
adjusted to suit your personal taste. Please note that
there

is always zero delay when switching INTO the

auto-rotation phase

, whose “Autorot” name cannot

be changed. However, you can set the transition time
which applies when you switch FROM auto-rotation
into another phase.

You now need to set up a method of switching be-
tween different fl ight phases by assigning the indivi-
dual phase switches or three-position switch.

Phase switches are assigned in the menu …

Assign the switch, e. g. the three-position switch SW 5
+ 6 under “C” or “D”.

The next step is to allot the fl ight phases you have set
up in the »

Phase settings

« menu to the individual

switch positions. Since you have already assigned na-
mes to the fl ight phases, these names now appear on

the screen: initially the name of Phase “1” is display-
ed on the right. If you operate the auto-rotation switch
(which you have already assigned), the screen dis-
play changes to “Autorot”.

Just to remind you:
The auto-rotation phase has absolute precedence.

Operate the auto-rotation switch again (if necessary),
then move the selected switch – in our example the
three-position switch SW 5 + 6 – to one end-point.
Use the rotary control to move to the

fi eld on the

right of the screen, and activate it. Now use the rotary
control to select the fl ight phase you wish to assign to
this switch position (in our example “2 Hover”) …

Alternatively you can immediately move the switch to
the other end-point and select the name – e. g. “Ae-
robat” – for this switch position. Proceed in exactly
the same way for the centre position of the switch, to
which we will assign the name “1 normal”.

Note:
Of course, it is perfectly possible to swap the names
over, or select different names for the three switch po-
sitions. For example, if you are using a speed gover-
