Yes im stupid aux 1 - 3 questions

lol i must be getting retarded or something but how to i set or remap buttons for aux channels

i have a quadcopter based on the cruis aio pro with a rx802 reciever
i use aux 1 for setting flightmodes these use to be aux 1 but with the new tx firmware i cant get it to work anymore

AUX1 is a receivers channel name. The RX802 should have it at channel 6 (ail=1, elev, thr, rudd, gyro, aux1=6, aux2, aux3) if it is similar to the 801.
So you define channel 6 in the mixer and make it depending on a switch, choose the values and a fixed curve and you're gone.

And it's never stupid to ask - not asking will be!

Ahh thanks for the help Rbe2012
still have to get used to the Deviation firmware
