142 Program description - Channel 1 curve | Helicopter models

Changing reference point values
Move the stick into the range of the reference point
that is to be changed: “L” (low), 1 … 4 or “H” (high).
The number and current curve value of this point are
displayed. Press the central

SET

button of the right-

hand four-way button to activate the Value field. The
reference point value displayed in inverse video can
be changed in a range of -125 % to +125 % without
influencing the neighboring reference points.

Example:

+50%

–75%

In this sample screen image, reference point “2” has
been set to -75 %.

Note:
If the stick does not coincide with the exact reference
point, please note that the percentage value on the
“Output” line always relates to the current stick posi-
tion.

Trim point function
Alternatively, jumping through active reference points,
in ascending or descending order, can be done with
the



selection keys of the left four-way button.

Note that “active” reference points are those which
have already been set. When a jump is made from
one to another, the point value field for the jump’s
destination reference point in the screen’s Point line
will be displayed in inverse video and its position in
the graph will be marked (L, 1 … max. 4 and H) in
inverse video and with a small triangle. The selection
keys on the right four-way button can then be used to
change the reference point jumped to as described

above, entirely independently of the control position.

One touch on the center

button terminates this trim point function.

Trim offset function
When a value field is active, i. e. in inverse video, it is
not only possible, as previously described, to jump
to and change a reference point already set with the



selection keys of the left four-way button but also

an existing curve can be vertically repositioned with
the



keys of the left four-way button within a range

of ±25 %:

A tap on the center

Trim x-axis function
This function is activated by tapping the left (



) or

right (



) selection key of the right four-way button

with an active (i. e. inverse video) value field. You can

then use the selection keys on the right four-way but-
ton to reposition the active point horizontally or verti-
cally as you wish:

Notes:
• If the point is repositioned horizontally further

away from the current control position than approx.
±25 %, a “?” sign will reappear in the line Point.
This question mark does not refer to the reposi-
tioned point, however: instead, it signifies that a
further point can be set at the current control po-
sition.

• Please note that the percentage value on the “Out-

put” line always relates to the current stick position
and not to the position of the point.

Smoothing the Channel 1 curve

In the example below, sample reference points have
been set:

reference point 1 to 0 %,
reference point 2 to +25 % and
reference point 3 to -75 %

as described in the last section:
