DJI Phantom 2 V2.0 Quadcopter 

The Phantom 2 Quadcopter v2.0 features a number of notable hardware updates over the previous Phantom 2 model from DJI, including more efficient motors, redesigned self-tightening props, a new transmitter (radio controller) with built-in battery and gimbal control dial, and other improvements. The Phantom 2 - for those who aren't familiar - is a quad-rotor UAV aircraft that can be great fun to fly standalone, but more than anything serves as a platform for capturing aerial shots using a GoPro HERO action camera (gimbal and camera available separately). It features a "Smart Battery" with integrated regulation circuitry that provides up to 25 minutes flying time; which is a substantive improvement over the original Phantom's still respectable 14 minutes.
