Hi,

I'm getting my list together for a Hexa copter and need help figuring out which batteries to get and how many.  I will be carrying a gopro2 and want to stay in the air as long as possible. I really have no clue, the 'get it' page links to this as an "inexpensive source": http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...

Here is my order list thus far, do you see anything to watch out for? Do I need anything else to get off the ground (other than batteries)?

ArduCopter Hexa 3DR Frame + Motors Kit (880kv motors)

ArduPilot Mega 2.0 Fully Assembled System (w/o gps)

3DR GPS LEA-6

Turnigy 9X 9Ch Transmitter w/ Module & 8ch Receiver (Mode 2) (v2 Firmware) (USA Warehouse)

Thanks for the assistance!
