The X4 H107C-HD Quadcopter with 2MP Video Camera in black and red from Hubsan is a quad-rotor, palm-sized RC helicopter that features a 2.4 GHz, 4-Channel transmitter and a built-in 2MP resolution HD camera. The most notable feature of this quadcopter is its size, even with a prop-to-prop wingspan of just 5.75" it sill has room for a camera. To record video there is a MicroSD/MicroSDHC memory card slot below the "tail" section that is activated using a button just to the side of the card slot. Finally, a 3.7V, 380 mAh lithium-polymer battery tucks away inside the body providing up to 7 minutes flying time.

The transmitter (TX) supports both Mode 1 and Mode 2 stick configurations. Mode 2 is typically preferred in the U.S. as many argue it more closely simulates actual aircraft controls, however some international users may be more accustomed to Mode 1.
