The hardware mounting and software tuning are all done prior to delivery. The Phantom is ready to fly the moment you unpack it, you just need to attach propellers, charge the LiPo and install the transmitter batteries before use. A compact and highly integrated design means that it is easier for you to pack it into your backpack. The streamlined design brilliantly reflects the aesthetics of its industrial design and the fantastic visual effects allows you to become the focus of the crowd. Moreover, you can mount a GoPro or other light and handy cameras on your Phantom to shoot some footage from the air which will bring you a brand new travel experience. INCLUDES REMOTE CONTROL (JUST ADD 4 X AA) Phantom contains a remote controller and receiver, which help the user to completely avoid the inconvenience of purchasing such things. The only thing you need to do is to add TX batteries (4x AA dry cell). The 2.4 G ISM frequency makes the effective control distance up to 300 meters (can be impacted by the specific flight environment). The frequency hopping anti-interference design allows multiple remote controllers to work at the same time, and provides a reliable remote communications link. STABLE, YET AGILE PERFORMANCE, EASY TO FLY Phantom has an integrated flight dynamics system, the Naza-M + GPS multi-rotor autopilot system, as well as the dedicated remote controller and receiver. Flight parameters and functions have been setup before delivery, so you can fly your Phantom the moment you receive it. The proven stability of the Naza-M autopilot system allows you to easily achieve great flight performance. TWO FLIGHT CONTROL MODES, INCLUDING POSITION HOLD With the built-in Naza-M autopilot system plus a GPS module, the Phantom has GPS Attitude and Attitude Control Mode. Pilots can switch between the two modes to achieve a particular flight experience.
