The X9503 2.4 offers a sophisticated program with easy 
preset trim positions for the elevator, flaps, flaperons 
(and even the aileron and rudder if you choose). The 
system can remain active in flight allowing you to fine-
trim presets in each flight mode or can be locked in so 
they cannot be altered in flight. Flight mode presets are 
automatically selected via the flight mode switch and are 
adjusted with the digital elevator trim, the digital flap trim 
and the digital auxiliary trim (flaperon). While the presets 
are adjusted via the digital trims, their positions are 
recorded in the servo monitor.
To access the servo monitor, in FUNC.LIST highlight 
MONITOR. Press the Selector to access the Monitor 
menu then press the Selector again to access the camber 
digital preset screen. To adjust the presets, move the 
flight mode switch to the land mode (down) position. 
Adjust the preset positions via the flap trim, auxiliary 
trim and elevator trim on the transmitter. The values will 
will display in the screen and then will be memorized for 
that flight mode. If you want these preset values to be 
fixed (not active in flight) once the values are established, 
return to the Trim Step screen in the system mode and 
reduce the value of the desired channel to 0. The preset 
values for all flight modes will be stored and no longer 
accessible with the digital trims. 
In 
FUNC.LIST, highlight D/R & EXP. Press the Selector 
to access the Dual Rate and Exponential menu. Highlight 
the channel (aile, elev or rudd) then press the Selector 
to select the channel you wish to adjust the dual and expo 
rates for. Rotate to select then press the Selector to store 
the desired channel. 
Note that three D/R and EXPO positions (values) are 
available (Pos0, 1 and 2).  
Under AUTO on the right of the screen, highlight LAND 
and press the Selector. Select POS2 as the active 
position for land mode by rotating the Selector and 
pressing the Selector when 
POS2 is highlighted. This 
automatically accesses dual rate and expo values that 
are programmed into position 2 whenever land mode is 
selected. Now rotate the Selector to 
POS2 and depress 
to highlight the D/R values. Rotate the Selector to 
change these values. Displace the aileron stick right or 
left to independently adjust the dual rate in each direction. 
Depress the Selector to store the desired D/R values. 
Rotate the Selector to the 
EXP Pos2 values and adjust 
these values in the same manner. Press the Selector to 
store the desired value. 
Now go back to channel and repeat for the two remaining 
channels. Press the LIST button to return to the Function 
Mode screen.
