A dogfight in the world of drones was about to begin. It was November 2016, and Da-Jiang Innovations Science and Technology, better known as DJI, was preparing to launch its killer new product: the Mavic Pro. Weighing just 1.6 pounds, the Mavic was compact enough to fit into a book bag and featured a four-mile flight range and a built-in camera capable of shooting pin-sharp 4K video from hundreds of feet up. Though priced below $1,000, the Mavic sported sophisticated gimbals to stabilize the camera and cutting-edge software enabling it to lock on subjects and follow them around, detect and avoid midair obstacles, and automatically return to its launch point before running out of power.
