With $500 million in reported sales in 2014, DJI sits at the top of an industry that shows no signs of slowing down. Now that the US FAA has opened up drones more for industry, DJI has launched a pesticide-spraying model along with a FLIR infrared camera. We may see commercial drone deliveries arriving soon as well, though many folks see that as unrealistic. At any rate, DJI has built the ultimate shrine for the flying robots, so you can visit it if you happen to be in Shenzhen -- you might want to bring earplugs, though.
