The X4 H107C-HD Quadcopter with 720p Video Camera in Royal Blue from Hubsan is a quad-rotor, palm-sized RC helicopter that features a 2.4 GHz, 4-Channel transmitter and a built-in 720p 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 memory card slot below the "tail" section that is activated using a button just to the side of the card slot. It will accommodated microSD/microSDHC/microSDXC cards up to 64GB. 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.How much is this in other site?
