The UDI U818A quadcopter comes completely assembled in the box and ready to fly after fully charging the battery, which takes about 2 hours. Flight time after a full charge is approximately 9 minutes, which is reasonably less than other similar beginner quadcopters. That being said, we highly recommend purchasing additional batteries with this drone. In addition, this quadcopter is excellent for the amateur pilot because it’s extremely easy to fly, and is virtually impact resistant – depending on the circumstances, of course.
Additional buttons located on the remote control allow you to perform stunts and difficult maneuvers, such as inversion. Do not attempt this feature until you get a complete grasp of how to operate the drone or you risk damaging your drone.
