Review on Quadcopter 4DRC V4, black by Amit Kumar ᠌

Children's toy, will go for the first drone to understand the principles of control. The battery lasts for 15-20 minutes, so it's good if there are three of them. Single battery is not an option. Then it's hard to find, take the maximum at once. Has pros: Simple control, There are a couple of "chips", for example, "flip", when the copter does a 360-degree roll on the fly. Or following a route drawn on your smartphone. 3 batteries included. Different cons: The camcorder does not connect to the phone. Shooting fails. If the drone flies 50 meters away, it loses connection and flies in an unknown direction. Light, wind interferes with control.
