I am selling this for a "friend" so might not be able to answer all your questions.
He said that this hexacopter kind of "just fell in his lap". He has no use for it and is willing to sell it cheap.
From research on line this thing new would go for around $2000.
It has a naza-m v2 gps chip on it (can't tell if it works or not).
Very cool copter. He is going to send pictures for me to post when he has a chance.
So, make your offers here
You know someone had to do this. Might as well be me. ;p
