the entry. This procedure is the same for the other
lines.
A tap, at the same time, on the  or  selection
keys of the right touch pad (CLEAR) will reset a field
displayed in inverse video back to "None".
"Point" column
The lines of the column "Mixer" were used to select
one or mixers. Now, in the "Point" column, the refer-
ence points to be trimmed will be set.
To do this, use the selection keys on the left or right
touch pad to move to the desired value field. Then
briefly tap the centre SET key of the right touch pad ...

Mixer Point
If a undefined point is selected – in the basic version,
only points "L" and "H" are set – the respective regula-
tor will remain ineffective.
The point offset (in a maximum range of about ±12 %)
L 1
for the selected mixer will simultaneously be dis-

played in the curve diagrams of the respective »Heli-
copter mixer« or »Channel 1 curve« menu so that

the offset can also be checked visually.

Phase Phase
The rightmost column is used, if desired, to determine
which programmed flight phase the given regulator
is to be active. The number preceding flight phase
names, in the example "1" (Normal)", are based on
the phase numbers as found in the »Phase assign-
ment« menu on page 160:

However, the current position of the regulator will
be – contrary to the corresponding fixed-wing pro-
gram – set to a new zero point when ...

column is to be changed.
Phase
In all of these cases, the current regulator position will
be stored and automatically overridden, i. e. adopted
into the curve characteristic, by the pre-programmed
curve points specified by the »Channel 1 curve« and
»Helicopter mixer« menus. In this manner it is pos-
sible to simultaneously optimize up to four arbitrary
curve points during the flight.

Program description - Profi trim | Helicopter models
The memory storage option described here is, for
example, useful during the first test flights of a new
model as this permits the "flown" flight corrections to
be immediately recorded in the program.
However, in order to have a clearly defined
reference point prior to the first time a store is
done, it is important to put all regulators into
their middle positions.
But always be careful that, after repeated stores,
servo travel is not too severely restricted on one side.
Check and correct the control linkage if necessary.
Sometimes, despite an optimal basic setting for the
model, it becomes necessary to temporarily change
reference points, for example, when the weather has
changed and the motor requires a short-term correc-
tion or even when the muffler gets a leak unexpect-
edly, etc. Of course, in all of these cases, the cor-
rected settings should not be stored via the Profi trim
option. Storage can be prevented by ensuring that the
regulator is in its middle position before activation or
deactivation.
Note:
Yet another point, independent of this, can be
regulated via the "Trim point function" through
use of the selection keys. This is described in
detail along with the programming of 8-point curves in
section »Channel 1 curve« on page 143.
