The world's fastest drone: Incredible footage shows Drone Racing League craft hitting record 179.6mph

Drone racing has become a big budget sport - and its biggest league has revealed the world's fast machine.

Called the RacerX, the craft recently set a Guinness world Record of 179.9mph - despite weighing just 800 grams.

The first prototypes of the drone burst into flames when hitting its highest point of acceleration, but the latest model, flown in Cunningham Park in Queens, New York, hit the record speed.
