What the heck is it or does it do?

Good question, but you are not going to get far with posting such little information.

it is a spelling error for Axmouth or in our world more likely Azimuth.

Why are you asking?

Geebax, now, you know it's the thingy hanging from the axis!

Absolutely right.  It's azimuth and it's the set of numbers at the bottom of the Go app.  What is the point of reference -- degrees back to me from the drone, degrees off North,   My map career has me processing an azimuth as the compass direction I am heading and computing a back-azimuth as what I need to do to get back?  

As a Navigator :

Azimuth is the bearing referenced to NORTH of a Celestial Body - usually used for Compass Error determination or position fixing.

Could you be more specific of your main issue? I'll attach a tutorial video of attitude indicator for your reference first.
