TRIM STEP
REV.SW – SERVO REVERSING
A-18
A-19
The Trim Step function adjusts the sensitivity of the
X9503 2.4 trim levers and switches. It allows quick
initial trimming of the aircraft, then makes precise
adjustments to aircraft trim after that. 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! When set to 0 the trim levers cease to
function and cannot change the trim of the aircraft.
When adjusting the digital trims (AILE, ELEV, RUDD,
FLAP, AUXT), the total trim travel does not change. Only
the number of increments (beeps) changes, which makes
for finer or coarser trim movements. When adjusting
the analog throttle 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 you are changing. Use the
Selector
to set a value of 1–10
(1 = finest, 10 = coarsest).
3. Repeat for other trims as desired.
This concludes the SYSTEM Menu portion of the ACRO
mode. Continue with FUNC.LIST to complete the aircraft
setup.
After defining the basic aircraft configuration in the
SYSTEM Menu, use the functions in the Function List
[FUNCT.LIST]
to complete the setup and adjust how
the aircraft flies. We present the functions (to the extent
practical) in the order they should be addressed when
setting up a new aircraft.
The descriptions are general in nature and are intended to
provide enough information to decide whether or not to
use a function and what types of selections and settings
to make.
Press the
LIST
button after the transmitter is powered up
to obtain the
FUNC.LIST

After plugging all servos into their proper channels in the
receiver, the first thing to check is the direction of travel
of each servo’s travel. Move all sticks and switches/levers
while observing each servo to determine if the servos
are moving in the correct directions. Make note of those
channels not traveling in the correct direction and use the
REV.SW function to reverse the direction of travel for these
channels.
1. Highlight and select
REV.SW
in the
FUNC.LIST
to
obtain the servo reversing display.
2. Use the
Selector
to highlight and select those
channels that need to be reversed. Pressing
the
Selector
toggles the channel between
Normal and Reverse.
