change or after long flight pauses.

sidering your settings are available in the “Tr” column

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
±30 % of total control travel.) The right column displays
trim memory content, currently filled uniformly with 0 %
because values have not yet been stored. Therefore,
the display appears like as follows:
Trim memory
AILE
ELEV
RUDD
+5% 0%
+3%
0%
–7%
POS SET
CH1 0% 0%
0%
normal
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:
Trim memory
AILE
ELEV
RUDD
+5% 0%
+3%
0%
–7%
POS SET
CH1 0% 0%
0%
normal
The trim value is stored in the trim memory when you
press the central SET button of the right-hand four-
way button; the setting is displayed in the right-hand
column:
Trim memory
AILE
ELEV
RUDD
+5% 0%
0%
+3%
–7%
POS SET
CH1 0% 0%

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

RUDD
+5% 0%
0%
+3%
–7%
POS SET
CH1 0% 0%
0%
normal
Simultaneously tap on the or selection keys of
the right four-way button (CLEAR) reset the value field
again back to “0 %”.
Trim memory

However, if you do not erase a trim memo-
ry before storing a new value, the new
value will be added to the stored value.
