Note:
More more information about the setting of
this "emergency shutoff", see the beginning
of the second following double-page.
Another tip:
Make a habit of giving all switches a common
switch-on direction; then a quick glance over
the transmitter prior to the ight should sufce – all
switches off.
Setting options for the "Autorotation C1 position",
"Motor stop", "Marking" and "Stick warning" are not
yet of particular interest …
… and the "Auto Trim" line should only be assigned
to a switch if "Initial trimming" is to be performed on
the helicopter in the context of a trimming flight. Fol-
lowing such a flight, this switch should be erased
once again, for reasons of safety.
Additional settings specific to helicopters are made in
the menu …

In the "Swashplate type" line, select control for
swashplate or pitch function. In this example:
"3Sv(2rol)".
The "Linearis. swashpl." line is not yet of interest.
In the "Rotor direction" line, it is established whether
the rotor – as viewed from above – turns to the right
(clockwise) or left (counter-clockwise). In other words,
whether it rotates counterclockwise or clockwise. In
this example "right".
Check the default for "Pitch min", which was adopted
from »General basic settings«, to confirm that the
entry "front" or "rear" is in keeping with personal pref-
erences or should be changed.

Mix ratios and mix directions for swashplate pitch, roll
and nick servos are already pre-adjusted to +61 % in

This menu can also be used to adapt travel and direc-
tion for individual servos. However, one must attempt
to retain 100 % servo travel so as to achieve the best
possible resolution and control accuracy. The direc-
tion of travel is determined with "Rev." and, in the
process, make sure that the direction is correct. The
tail rotor servo must run so that the nose (!) of the
