It's a sport of the future, but could it be over in the United States before it even takes off?
Participants describe drone racing like NASCAR but with flying robots equipped with cameras.
Here's how it works. Pilots fly the drones around a course using a remote control. Typically, racers wear large goggles, broadcasting live, standard definition video from a camera mounted on the drone.
Races can take place in large open fields but experts say that could soon change as the sport grows in popularity.
Race organizers are already considering conducting races in abandoned buildings and forests.
New York based Drone Racing League already held several races last year. It plans on making a big splash in 2016. Miami Dolphins owner Stephen Ross has invested $1 million in the company.
Meanwhile, the airline industry fears the safety implications of the sport.
The Federal Aviation Administration has created a drone task force. New rules require drone users to register their device with the FAA, similar to the way it's done in Canada.
