Most Common Switch for Arming?

[PTMC]

I’m working on setting up my first real mini quad a Nazgul Evoque after spending just about a year flying the DJI FPV. Using the TBS Tango for a radio and the DJI goggles. Anyway, I’m sure its personal preference but is there a preferred side left/right to assign the arm/disarm switch? I’m also conidering interlocking the arm step with one of the momentary switches. Thanks

I use the two position on the upper back left. The SF switch on my TX16s. It's the only two position switch. I believe the F switch on your Tango 2 is a momentary switch so I would use the A button which is a two position switch.
