My Aurora 9 transmitter "Channel Function" screen shows the followng:
Ch6 - AUX 1
Ch7 - AUX 2
Ch8 - AUX 3
Ch9 - AUX 4
The Aurora 9 Manual contains no references to "AUX" or "auxilliary".
I assume that these channels are available for various functions to be programmed by the user.
I want to program channel 6 to activate a servo for an engine kill switch. How is this done ?

(or even one of one of the extra trim buttons for controlled short throws.. 
Visit Model Menu [Monitor] and you will see Ch6 is then operative as On/OFF, reverse servo if necessary under the Model Menu [Reverse] window.
