What is the "main wing" referrence I see currently?
Is it to clearify it is not the "little wing" on the rear of the craft?
Or is it a carry over from "main gear and tail gear?"
Yes you've got it, the term "main wing" is just to clarify that's not the "little wing" on the rear, which may be also called horizontal stabiliser or stab.
