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.
Overall you can’t go wrong if you’re looking for in the toy drone section with something for a camera to play with. The HD 720p camera takes great video and pictures. The price is right at under $130.00 amazon, and really the customer service is the kicker. No other drone company we’ve spoken to has displayed such dedication to making sure their customers are happy.

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.
