Features: - Includes Hold altitude for easier flying. - Indoor and outdoor. - Avanced technology with IOC (headless mode) and backwards button. Specifications: - 2 Li-po battery 3,7v and 380mAh - Product size: 320x320x70mm - Kind Of Transmitter: 2,4ghz - Transmitter Frequency: 2,4ghz - Rc Channels: 4ch - Battery (V) (Ma): Li-Po 3,7 V - 350 Ma - Helicopter Motor: 4 - Rotor Type: Multirotor - Charger Included: Yes - Heli/Airplane Assembly: Rtf Technology: 2,4ghz: - Control Radio stations are widespread in the issuance of the 2.4 GHz frequency, using multiple frequencies under a stipulated order. This frequency works totally different from the old ones using a crystal with a fixed frequency, these latest issue in a wider band called DSS (Dynamic distribution spectrum) The particularity of DSS is not transmitted on a single frequency, but uses multiple frequencies in a controlled manner. The particularity of DSS is not transmitted on a single frequency, but uses multiple frequencies in a controlled manner LI-PO BATTERY: - Lithium polymer battery, rechargeable batteries. generally composed of several identical secondary cells in parallel to increase the capacity of the discharge current, and usually are available in series ´´packs´´ to increase the total voltage available. One element of Li-Po has a nominal voltage, loaded, 3.7 V. Never discharge a battery below 3.0 V per cell. slow loads for longer life cycle is recommended for batteries of more than one item is required balancer charger. If no use in a time period, it is necessary to leave them loaded on 75% capacity. Auto Return: - Also Known as Auto Return, Go Home, Homecoming. Help button once with the Drone in flight, in case of losing control of the Drone, quickly tighten and the machine starts to fly back until the pilot touch either sticks, then automatically deactivates this mode and drone again be controlled from the station normally. In no case will land alone or return to the launch automatically.
