This past weekend, 145 competitors from around the world gathered on New York City’s Governors Island for the second annual U.S. National Drone Racing Championships. The winner was Zach Thayer from Laguna Niguel, California, of Team Big Whoop. But the biggest news was the presence of ESPN, which streamed the competition live—a first for the country’s leading sports broadcaster.

Racing drones are small, highly maneuverable multirotors capable of exceeding 80mph (and, thus, drain their batteries in two or three minutes). The sport has experienced a significant spike in interest and investment in the past two years. On August 5, MarketWatch reported that there is “money pouring into drone racing”—not only from ESPN, but also corporate sponsors such as Pepsi, GoPro, accounting firm Ernst & Young and insurer AIG. The Drone Sports Association, the organizer of the U.S. National Championship, now hosts drone racing events in over 40 countries, according to its website. A new 24/7 digital channel, Drone TV, was launched in July; in addition to around-the-clock highlights, it will include 10 new one-hour programs each week. Drone racing specials have recently aired on the Science Channel and Discovery Channel, introducing the broad public to unmanned aerial systems technology. The attention is set to continue to grow as several race leagues emerge and compete for fans and investment. Here’s what you need to know.

Technical Fundamentals

The drone racing boom has been enabled by four recent technical advances:

History

  • Serious organized drone racing is a very recent phenomenon, but FPV technology, the key enabler for the sport, has a longer history. In a 2011 article, Smithsonian’s Air & Space magazine traces the birth of FPV remote control aircraft to the late 1990s, when cameras and transmitters became light enough to fit on small unmanned aircraft. The first high-profile use of fast, agile FPV-equipped drones similar to those used in drone racing today was a series of flights by Raphael “Trappy” Pirker and his Team Black Sheep, who gained widespread acclaim and notoriety for flying around the Statue of Liberty in New York, among other places. In 2014, an RC flying club in eastern France posted a video of a “Star Wars-style” race in a local forest that attracted more than 3 million views on YouTube.

  • The first U.S. National Drone Racing Championships, organized by Rotor Sports, was held in July 2015 in Sacramento, California, drawing more than 100 competitors. Chad Nowak, an Australian drone-racing pioneer known as FinalGlideAUS, won every event: the race, freestyle and team competitions.
  • In March 2016, a custom-built track and $1 million in prize money drew more than 150 racers to Dubai for the World Drone Prix, which is not affiliated with the Drone Racing Championships. The first prize, $250,000, went to 15-year-old Luke Bannister of England, who also took the top spot in a drone race the following month at London’s iconic Wembley Stadium.

How it works

  • Drone racing puts a premium on both speed and maneuverability. Races are generally short, often lasting under a minute. Crashes are common. The most popular format has a group of pilots race at the same time over a course with multiple gates or other obstacles. The first drone to arrive at the finish line after a set number of laps wins.
  • During races, pilots use FPV goggles that display a live feed from a camera mounted on the front of the machine. Pilots rely on a real-time transmission from the drone: even brief lapses or slight jumps in latency can result in a crash.
  • Unlike most consumer quadcopters, which have their four rotors arranged in an X-shape configuration, many racing drones feature an H-shape layout. They are also generally smaller than popular drones like the DJI Phantom or 3DR Solo. A typical racing drone is about 250mm wide, measured diagonally, compared to the 350mm of a DJI Phantom 4. Crucially, these systems are much faster than consumer drones. Racing drones can reach speeds of over 80 mph, compared with the Phantom 4’s listed top speed of 45 mph. (See a breakdown of the technology in the Drone Racing League’s Racer2, and a comparison with typical consumer drones, here.) In other leagues, most racers build their own machines, but some hobby drone suppliers, including Horizon Hobby, have begun offering off-the-shelf racing drone kits.

The Landscape of Drone Racing

  • With interest from ESPN, GoPro, Mountain Dew and major investors, several leagues are vying for supremacy. The Drone Racing League has so far received more than $8 million in funding, including a $1 million investment from RSE Ventures, a firm run by Miami Dolphins owner Stephen Ross. The DRL’s first race, in February 2016, was held at Dolphins’ New Miami Stadium. A second race was filmed in March but has not yet been posted online. The league did debut a new site in early August, droneracingsafety.org, that offers detailed advice on organizing a drone race.
  • The Drone Sports Association, which hosted the 2016 U.S. National Championship, will host a World Championship in Hawaii in October. The event will also be broadcast by ESPN. The DSA was formed in July of this year, following an aborted merger between its predecessor, RotorSports (which organized the 2015 National Championship), and the International Drone Racing Association (IDRA).
  • The IDRA was a partner in the World Drone Prix in Dubai and signed the initial broadcast agreement with ESPN when IDRA was set to organize the 2016 U.S. National Championship. After that event came under the auspices of the Drone Sports Association, the IDRA sanctioned the GiGA Drone Racing World Masters in South Korea—that event occurred on the same weekend as the U.S. National Championships. The association’s future plans are not yet clear.
  • The new DR1 race series, which launched this summer with a race at Sepulveda Dam in Los Angeles, is sponsored by Mountain Dew and streams live on Twitch. DR1 is perhaps the most prolific content producer among the rival leagues, with its inaugural DR1 Invitational featured on the Discovery Channel and the Science Channel, in addition to online streams.
  • DR1 has also established a partnership with the MultiGP Drone Racing League, which claims more than 700 chapters worldwide and nearly 10,000 pilots. MultiGP is taking an explicitly grassroots approach for its 2016 Drone Racing Championship, featuring open regional knockout competitions leading up to the final on Labor Day weekend at the Academy of Model Aeronautics headquarters in Muncie, Indiana.
  • There have been many drone racing events organized by regional entities. One notable example is Las Vegas’ Xtreme Drone Circuit, which includes flaming hoops as obstacles. It is scheduled to host its third $10,000 tournament on Sept. 9.

Regulations and Drone Racing

  • Several regulatory questions hover around drone racing in the U.S., starting with the cornerstone enabling technology of the sport: FPV. A June 2014 FAA interpretation of the Special Rule for Model Aircraft states that these regulations “preclude the use of vision-enhancing devices” including “goggles designed to provide a ‘first-person view’ from the model.” Under the long-awaited Part 107 rules, which take effect August 29, commercial drone operators are required to maintain a direct, unaided visual line of sight with the drone, a requirement that potentially precludes the use of FPV systems by pilots. Part 107 rules also prohibit the use of drones over people who are not involved in the drone operation.
  • But more broadly, it is unclear whether drone racing, which is organized by for-profit businesses, counts as a “hobby or recreational” use of drones according to Public Law 112-95, Section 336(c), which exempts model aircraft flights from new FAA rules.
  • Events that are held indoors are not subject to FAA airspace regulations. The Drone Racing League’s events so far have been held inside buildings such as abandoned shopping malls. The FAA has demonstrated interest in drone racing; according to an August 2015 article in IEEE Spectrum, two of the agency’s representatives attended the 2015 National Drone Racing Championship.

The Future of the Field

  • Drone racing could be ideal content as virtual reality hits the mainstream. Matt Higgins of RSE Ventures told ESPN that drone racing “has all the makings of a modern-day sport: Twitch meets Formula One.… and first-person viewing lends itself to an amazing spectator experience with virtual reality.” The problem is, current technology still isn’t good enough to transmit first-person footage in HD — and even pilots say it takes a while to get over the nausea brought on by all that high-speed motion.
  • Eventually, human pilots might be able to ditch their handheld controllers. This April, engineering students at the University of Florida held the first brain-controlled drone race. Contestants directed DJI Phantoms in a slow-motion sprint over a 10-yard course.
