What exactly doesn't work? More details are needed to figure out exactly what is wrong.
If you have the spektrum subsystem loaded in the firmware section of the airframe file, it should be working, assuming you bind the satellite to the transmitter.
Note that the spektrum subsystem does NOT use a radio control xml file (but you still need one in the conf.xml, you can use spektrum.xml or dummy.xml or something).
If you want to set up two two-way switches to get three modes (i.e. one switch manual/auto, the other auto1/auto2 depending on the state of the first switch), that is certainly possible, like bullet 1 here:
Hopefully that helps.
