The Turnigy transmitter has a three position switch labeled F.MODE, AUX3,MIX. I would like to use this switch to select the flight mode on my quad. Using the menu system, I can go to [AUX-CH]. Here I find the AUX-CH channels listed 5 through 9.  When I try to find the F. MOD switch I cannot do so. Is there a trick here I do not know? I am trying to use the F MOD switch to select the flight mode on my Revo.

I wonder if it needs to be set up as AUX.  Maybe F.MODE changes something in the transmitter, but doesn't actually control a channel.  AUX sounds like it would control a channel.
