Altitude Hold The drone will constantly move to a predetermined height, which facilitates control. Great drone for children and beginners. Battle Drone Fun Compete with the opponent firing the infrared, the drone will land slowly after 4 strokes. Headless mode You do not need to be anxious or confused with the direction of the drone when it flies away. In this mode, the front is in any way that the pilot is watching. Flight time 9 minutes, 3-speed mode, 3D flips, emergency stop, recalibration of a key. A key start / landing The quadcopter is equipped with a key that starts and lands, which makes the drone easier to fly and better to control.
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position.  ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.
Likewise, ensure that your device is equipped with headless mode, which is a cheater mode that allows you to treat any direction that the drone goes as forward so that you don’t have to worry about how to flip it around safely and control it back to your location after completing a flight. With headless mode, all you need to do is just push the joystick in the corresponding direction that you want the device to travel.
Another one of the great drone on this list with the beginner in mind, the UDI 818A HD Drone is electric powered, radio controlled, and equipped with six gyroscopes for stabilization. Although it can take a decent beating, it is recommended that this drone not be flown above asphalt or concrete, as it is still made of plastic, and can break if improperly used.
