Hey Guys I am looking at a Air 2 No s, it is only supposed to have 3.18 flight hours and I do not know if unit is unbinded. It is at a Pawnshop and it is fly more Combo So it has three batteries they want $600. But I think I can get it for less. But have No Idea what a Air 2 fly more is worth. Most of the Air 2 are the S model. So What do you think?
