The Trim Step function provides for adjusting the
sensitivity of the trim levers. It is useful during and after
initial trimming of the aircraft, in order to trim the aircraft
quickly at first and then make precise adjustments to
aircraft trim. When adjusting the digital trims (AILE,
ELEV, RUDD, FPRN, FLAP), the total trim travel does not
change—only the number of increments (beeps) allowing
finer or coarser trim movements. The digital trims
may have a setting of 0–10 with 10 being the coarsest
adjustment. When the value is set to 10, there are only
10 trim increments from center to each end. When set to
5, there are 20 trim increments from center to each end.
When set to 4 there are 25 increments. When set to 3
there are 34 increments and when set to 1 there are 100
trim increments. At 0 the trim levers cease to function and
can no longer be used to change the trim of the aircraft.
When adjusting the analog spoiler trim, however, the
total trim travel is actually reduced when set to less than
100%.
Use a fairly coarse setting such as 4–6 when test flying an
aircraft in order to trim the aircraft quickly, then use a finer
setting such as 3–1 for final precision trimming.
1. Highlight and select
TRIM STEP
in the
SYSTEM
Menu
to acquire the
TRIM STEP
display.
2. Highlight and select the trim and use the Selector to
set a value of 1–10 (1 = finest, 10 = coarsest).
3. Repeat for other trims as desired.
Use the device select screen to select the following:
• To assign/activate flight modes to a variety
of switches
• To assign the motor function to spoiler the stick,
levers or switches
• To program the digital aileron and rudder
trims so they are common or separate in
each flight mode
• To assign the flap (camber) adjustment to one of
the two available side levers
• To assign aux 2 channel to various levers,
switches or sticks
• To assign aux 3 channel to various levers,
switches, buttons or sticks
• To assign aux 4 channel to various levers,
switches, buttons or sticks
• To activate or inhibit the motor, aux 2, aux 3 and/or
aux 4 channels
• To determine the direction of the flight mode switch
Flight Modes allow you to program and select nearly all
of the parameters (e.g. dual rates, camber adjust values,
preset trims, all types of mixing, etc.) in flight via a
switch(es). The X9503 2.4 offers up to 5 flight modes that
include Launch, Land, Cruise, Speed and Thermal. Flight
modes allow a sailplane’s programming to be optimized
for up to five tasks.
As an example, typically in launch mode:
• The flaps and flaperons are preset with positive
camber to give more lift.
• An elevator preset trim position giving the best
climb is programmed.
• A high rudder rate with reduced exponential to
give authoritative steering control on launch is
programmed, while the elevator and aileron rates
are set to give a medium response.
• Aileron-to-rudder mix is turned off, as are
landing flaps and elevator-to-flap mix. Camber
adjustment of the side lever is programmed to
give proportional camber changes allowing for last
minute adjustments based on wind and launching
conditions.
• Aileron differential is set at 50%.
You can select these programming parameters and many
more by moving one switch. At the top of the launch you
prepare to zoom by switching to the cruise mode. A single
flip of the switch neutralizes the trailing edge while giving
the correct elevator trim for cruise. Rudder-to-elevator
and elevator-to-flap mixes automatically turn on the
programmed values and the aileron differential is now at a
much higher 75% for more coordinated thermal turns. At
the flip of a single switch you’re ready for a zoom launch
and for hunting thermals! And there are 3 more flight
modes available. Once you start using flight modes, you’ll
wonder how you ever flew without them.
