There are two functions in the SYSTEM Menu that 
control some of the more advanced features of the X9503 
2.4 system. They are the Devic. SEL and 
Swash Type functions.
The Devic. SEL function activates and deactivates 2 
additional Flight Modes; changes switch assignments 
from the system defaults; activates and deactivates 
switches/channels, activates/deactivates the Hover 
Throttle, and Hover Pitch levers, and activates/deactivates 
the Governor function.
The Swash Type function indicates the Swashplate type 
(Normal (1 Servo), CCPM 180, 120, 140, and both 3 and 
4 servo 90).
Each of the options in these two functions is described 
below to the extent necessary to determine if they should 
be used for the helicopter being programmed.
The X9503 2.4 offers the pilot up to 6 separate flight 
modes. The X9503 2.4 is factory preset to offer the pilot 4 
separate Flight Modes (N, 1, 2, H). There are 2 additional 
flight modes, numbered 3 and 4, that can be activated 
through the Device Select function.
To Activate 2 Additional Flight Modes 
(Flight Modes 3 and 4)
1. From the SYSTEM Menu highlight and select Devic. 
SEL by using the Rolling Selector.
2. Highlight and select F.MOD Extra using the Rolling 
Selector. When selected, five options appear: AIL 
D/R, ELE D/R, RUD D/R, HOLD SW, and GEAR 
SW. Highlight and select the switch you want to 
access Flight Modes with while flying. The example 
below shows the GEAR switch selected.
Once Flight Modes are activated, two additional sets of 
Throttle and Pitch curves numbered 3 and 4 will appear in 
the Function Mode. 
The Rud Trim function allows the pilot to choose between 
1 set of trim settings for the Rudder channel only in all 
flight modes (COM) or a separate set of trim settings for 
each of the flight modes (FM).
You can toggle the RUD TRIM:COM parameter back and 
forth between COM and FM by pressing the Rolling 
Selector when COM or FM is highlighted. If left in the 
COM mode, the digital trim for rudder is Common or 
shared by the 3 Flight Modes. If you select FM, the X9503 
2.4 keeps track of the digital trims independently for each 
Flight Mode, meaning you can re-trim the rudder using 
the digital trims for each Flight Mode. 
To change one or more switch assignments:
1. From within the Devic.SEL function, use the 
Selector to highlight and select THRO HOLD, PIT 
Trim, GEAR, AUX2, AUX3, or AUX4 along the top 
line of the display.
2. Once you select a switch, a list of available replacement 
switches displays. Highlight and select the desired 
switch with the Selector.
The X9503 2.4 provides the ability to change the 
standard default switch assignments for THRO Hold, 
PIT Trim, GEAR, AUX2, AUX3, and AUX4. Changing the 
assignments may be a matter of preference or to help 
overcome a disability in one hand. In any event, the 
standard switch assignments may be changed in Devic.
SEL function contained in the SYSTEM Menu.
3. Repeat for as many switches as desired.
