with the cd selection keys of the left or right touch
pad, the entry fi eld will be framed.

The »Pitch min.« line is used to adapt the actuation
direction of the throttle/pitch joystick to personal
control preferences. All other helicopter program
options which involve throttle and pitch functions, e.g.
throttle curve, idle trimming, tail rotor mixer, etc., are
dependent on this setting.
Tap the center
SET key of the right touch pad. The
operating direction of the throttle/pitch joystick will be
displayed in inverse video. Now choose the variant
needed with the selection keys of the right touch pad.
Pitch
These mean:
"fwd.": minimum pitch setting when the pitch
joystick (C1) is "forward", i.e. away from
the pilot.
"rear": minimum pitch setting when the pitch
joystick (C1) is "back", i.e. toward the pilot.
A simultaneous tap on the cd or ef keys of the
right touch pad (CLEAR) will set this option to "rear".
Notes:
C1 trimming affects only the throttle servo. •
The so-called "throttle limit" is set by default, see •
text beginning page 117, by way of input "GL16" in
the »Control adjust« menu with which the throttle
servo can be limited, independent of the pitch
servo, in the full throttle direction.
Since a given user's models will typically be •
operated with the same pitch-min direction, this
specifi cation can be conveniently preselected
in the "transmitter-specifi c" »General basic
settings« menu, page 259. This specifi cation will
then be adopted automatically when a new model
memory is created in the »Helicopter type« menu
but, if desired, can be adapted on a model-specifi c
basis as described.
Expo throttle limit
After selecting the »Expo throttle lim.« line with the
cd selection keys of the left or right touch pad, the
entry fi eld will be framed.

The "Throttle limit" function described in the »Control
adjust« menu, see page 117, can be assigned an
exponential characteristic curve.
A pitch progression rate between -100 % and +100 %
can be set with the selection keys.
For example, it is practical to have the throttle
limit – by default, the right-side proportional rotary
slider – also regulate the idle setting. Further details
about the throttle limit can be found in the text for the
»Control adjust« menu beginning page 112.

If the carburetor is open too far when the transmitter
is switched on, an acoustic warning will be sounded
and a warning will be presented in the display.

The »Thr. limit warning« option permits the setting of
a variable for the critical position of the throttle servo
between 0 % and -100 %, above which the warning
will be issued. The reference point for this option is
the "fwd." or "rear" Pitch min. joystick position set in
this menu.
