Digital trim with visible and audible indicators
Both sticks are equipped for digital trimming. By de-
fault, turning trim wheels will offset the stick's neutral
position by 4 increments (out of a possible 100 steps
per side). This offset is also reported acoustically. A
brief press on the trim wheel will reset an existing
trim offset back to "0". Any other "zero points" can be
specified with the help of the »Trim memory« menu.
If flight phases have been created and each assigned
with a fitting name in the »Phase settings« (page
154) and »Phase assignment« (page 160) menus,
then these names will appear at the bottom left in the
»Trim memory« menu (page 240 to 242) and their
trim values will be stored on a flight-phase specific
basis.
The default 4-steps per click increment range placed
in every new model memory upon initialization can
be changed at any time in the »Stick mode« menu,
page 114 or 116, separately for each stick plane, in a
range of 1 … 10 for fixed-wing models and in a range
of 0 … 10 for helicopter models. (A trim function can
be deactivated by selecting "0" steps, which can be
advantageous in helicopters with certain gyro sys-
tems.)
Current trim values are automatically stored when a
model memory change is made. Furthermore, – ex-
cept for the trim of the throttle/airbrake stick, the
so-called "C1"(channel 1) control function – digital trim
can be set to operate globally or on a flight-phase
specific basis within a memory location. This choice
is made, separate for each stick plane, in the second
column of the »Stick mode« menu, page 114 or 116.
Notes:
•
Finding the mid-point position during a
ight is easy and can be done without
even looking at the display. A brief press
on the trim wheel will reset trim to "0" or, in the
»Trim memory« menu, will reset a stored ight-
phase specic trim value.
• The "cut-off trim" function, known from other
Graupner remote control systems in the mc and
mx series, and typically described in this section
can be realized with the help of the "Thr. CutOff"
option in the »Basic settings, model« menu,
see page 90 and 101.
