Trim:com (Flight Modes; D/R:sw (Flight Modes - JR X9303 2.4 Instruction And Programming Manual

TRIM:COM (Flight Modes)

The TRIM:COM parameter can be toggled back and
forth between COM and FM by pressing the Selector
when COM or FM is highlighted. If left in the COM
mode, the digital trims for Elevator, Ailerons, and Rudder
are Common or shared by the 3 Flight Modes. If FM
is selected, the X9303 2.4 keeps track of the digital
trims independently for each Flight Mode, which means
the pilot can re-trim the aircraft using the digital trims
for each Flight Mode. This is a very useful feature if
switching between Flight Modes causes the aircraft's trim
to change, such as when flaps are deployed by one of
the Flight Modes causing a slight roll. In this case, the
pilot can simply use the Aileron digital trim to trim the
Ailerons, eliminating the roll tendency when that Flight
Mode is selected. Selecting other Flight Modes brings in
a corresponding set of trims, ensuring the aircraft stays
in trim as the pilot changes between the 3 Flight Modes
during flight.

D/R:SW (Flight Modes)

The D/R:SW parameter may be toggled between SW
and FM by pressing the Selector when SW or FM is
highlighted. If left in the SW mode, then the 3 Dual Rate
switches will be used to select Dual Rates and Exponential
settings for Elevator, Ailerons, and Rudder and there
will only be 2 sets of Dual Rates/Expo settings for each
control. If FM is selected, the Flight Mode switch will
be used to select Dual Rates/Expo settings for all three
controls at once (Elev, Aile, Rudd - D/R settings ganged
together on the Flight Mode switch) and there will be 3
sets of D/R/Expo values available for each control.

If Flight Modes are only going to be used to switch
between 3 sets of Dual Rates/Exponential settings, then
leave the TRIM parameter set to COM. If other functions
are to be controlled by Flight Modes which may have a
tendency to cause the aircraft trim to change, then select
FM for the TRIM parameter. The example below shows
FM selected, meaning that each Flight Mode has its own
set of trims. The setting can be changed at any time by
returning to this display.
Note: When trims are set to FM, be especially
careful during the first flight of an aircraft to
remember that the aircraft will need to be trimmed
using the digital trims for Aileron, Elevator and
Rudder for each Flight Mode selected during flight.
If the aircraft is badly out of trim, it will probably be
badly out of trim for each Flight Mode selected. If the
out-of-trim condition is very severe, it might be wise
to land after trimming the first Flight Mode and then
note the trim settings. Switch to the other 2 Flight
Modes and match the trims to these settings before
flying again.

If individual D/R switches (3 switches) to control only 2
sets of rates and curves for Elevator, Ailerons and Rudder
are desired, set this parameter to SW. If 3 sets of rates and
curves that are selectable by a single Flight Mode switch
are desired, then set this parameter to FM. This setting
may be changed at any time by returning to this display.
