This menu permits selective storage of the given
current position for the four digital trim controls in
order to return them afterward to their visual middle
points. This makes the last stored trim positions in the
respective middle positions of trim levers for control
functions 1 ... 4 available again following a model
memory location change or after long flight pauses.
This memory store process is effective on a flight-
phase specific basis for the currently active model
memory location and is not to be stored globally.
Therefore, as soon as flight phases have been de-
fined in the »Phase settings« and »Phase assign-
ment menus, the given active flight phase will be
displayed on the screen's bottom line. For example:

Storing trim positions
The model has been flight tested and trimmed dur-
ing the test flights. Current trim positions are now
displayed in the column "POS" located approximately
in the middle of the display. (The trim range is about
SET
±30 % of total control travel.) The right column dis-
plays trim memory content, currently filled uniformly
with 0 % because values have not yet been stored.
Therefore, the display appears like as follows:
0%
0%
0%
CH1

AILE

ELEV

Now use the selection keys on the left or right four-
way button to move to the line where a trim value is
to be written into trim memory, e. g. the elevator trim
value:
CH1
AILE
ELEV
RUDD
The trim value is stored in the trim memory when you
press the central
way button; the setting is displayed in the right-hand
column:

Now, if desired, change the flight phase and repeat
the procedure. Perform the same procedure for the
other control functions, as necessary.
Erasing stored trim positions
Use the selection keys on the left or right four-way
button to move to the line where a trim value is to be
erased from trim memory, e. g.:
Trim memory
CH1
0%
AILE
+5%
ELEV
0%
RUDD
–7%
nor mal
POS
Simultaneously tap on the or selection keys
of the right four-way button (CLEAR) reset the value
field again back to "0 %".

However, if you do not erase a trim memory be-
fore storing a new value, the new value will be
added to the stored value.
Although this an "elegant" way to effectively offset
servo throw beyond the normal trim range of about
±30 %, do keep in mind that excessive offsets for
servo travel can lead to anomalies including one-
