DJI on Thursday unveiled its Spark drone that is designed to be flown by anyone. DJI”s other drone products are typically popular among professionals, such as photographers and videographers, who are willing to spend big bucks on high-end equipment. The Spark, by contrast, will cost just $499, requires little training and can fit in the palm of your hand, the company said. DJI said the Spark can be controlled by gestures, using different hand movements to move the drone around you and even capture images with the drone”s built-in camera that”s capable of recording 1080p HD video. Using GPS, it can quickly return home.
