"Global":

The position of the respective trim
wheel is effective "globally" for all ﬂ ight-
phases programmed for the given model,
page 140.

"Phase":

The position of the respective trim wheel
is effective on a phase-speciﬁ c basis and
will be automatically stored upon change
of ﬂ ight phase so that the setting is again
available following a return to this ﬂ ight
phase.

A simultaneous tap on the

keys of the

right touch pad (

CLEAR

) will reset the option back to

"Global".

Trim steps

The four digital trim wheels shift the neutral point of
the respective joystick 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, independent of the selected number of trim
steps, is always about ±30 % of control travel.
After selecting the "Tr. step" column and the desired
trim control with the

selection keys of the left or

right touch pad, the corresponding entry ﬁ eld will be
framed.

A simultaneous tap on the

keys of the

right touch pad (

CLEAR

) will reset any change made

to the active ﬁ eld back to "4".

Time

The rate of control signal change with respect to the
speed of joystick motion can be inﬂ uenced by the
entries made in the "– time +" column. Each joystick
movement direction, i.e. joystick 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
signal and therefore also commensurately on any
servos controlled by the effected controls.
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. In
this latter case, the given stick control is to be moved
to the respective side so that the inverse video ﬁ eld
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
middle 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 function 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:
