trim controls for the lines "Roll", "Pitch ax" and "Tail
rot." can be switched over from "Gobal" to "Phase"
and vice versa, for example:
Thr. GA 4 0.0s
Roll PH 4 0.0s
Nick PH 4 0.0s
Tail GL 0.0s

• "Global"
The position of the respective trim function is effec-
tive "globally" for all flight-phases programmed for
the given model, page 146.
• "Phase"
The position of the respective trim function is ef-
fective on a phase-specific basis and will be auto-
matically stored upon change of flight phase so that
the setting is again available following a return to
this flight phase.
A simultaneous tap on the  or  keys of the right
four-way button (CLEAR) will reset the option back to
"Global".
Column "St"
The four digital trim switch-keys shift the neutral point
of the respective stick in the given direction by one
adjustable increment, as set here, for each "click". This
is where the increment size (step) can be adjusted for
a given direction, whereby maximum trim travel, inde-
pendent of the selected number of trim steps, is always
about ±30 % of control travel.
After selecting the "St" column ((trim) steps) and the
desired trim control with the  selection keys of the
left or right four-way button, the corresponding entry
field will be framed, for example:
Thr.
Roll
Nick
Tail

Briefly tap the centre
button. The current setting will be displayed in inverse
+
video. Now select the desired value, between 1 and
10, with the selection keys of the right four-way button,
for example:
Thr.
Roll
Nick
Tail
A simultaneous tap on the  or  keys of the right
four-way button (CLEAR) will reset any change made
to the active field back to "4".
Column "- time +"
The rate of control signal change with respect to the
speed of stick motion can be influenced by the entries
made in the "– time +" column. Each stick movement
direction, i. e. stick control channels 1 through 4, can
be set individually. This means that respective servos
will then follow rapid control position changes only
at an accordingly delayed rate. This time delay has a
direct effect on the control function and therefore also
any servos controlled by this function.
The time can be programmed symmetrically for both
sides or separate for each control direction. This setting
has a programmable range of 0 s to 9.9 s.

Program description - Stick mode | Helicopter models
In the case of side-separate settings, the stick is to be
moved to the respective side so that the inverse video
field will switch between sides to the one for which the
change is to be made.
Example:
All three servos are to be actuated for swashplate
pitch control, e g. a "Pitch" control movement for a
"3Sv (2Roll)" swashplate. However, travel for the mid-
dle servo is greater than that of the other two servos
on the shorter lever.
A rash "Pitch" control movement would not operate
the nick servo in the middle as quickly as it would the
two roll servos on the shorter lever. This would cause
a momentary control motion in the "nick" direction.
However, if response time for the "pitch" control func-
tion were to be reduced by at least the positioning
time for the servo in the middle then all three servos
would reach their proper positions at the same time.
The necessary delay times typically amount to only a
few tenths of a second. For example:
Thr. GA 4 0.2s
Roll PH 4 0.0s
Nick PH 8 0.0s
Tail GL 4 0.0s
