The Drone Racing League (DRL) has managed to build the fastest drone in the world: the DRL RacerX, which is actually capable of reaching a top speed of 179.6 MPH, has claimed the Guinness World Record at 163 MPH. (The official recorded speed is lower because the organization requires an average of the different speeds documented on the measurement course.) The previous record was 125 MPH. ...the Drone Racing League (DRL), the global leader in professional drone racing, tested the fastest racing drone, and set the Guinness World Records title for the fastest ground speed by a battery-powered remote-controlled quadcopter. Hand-built by DRL's Director of Product, Ryan Gury, and DRL's team of expert drone engineers, the drones fly at unprecedented high speeds. The fastest racing drone, the DRL RacerX, zooms at a never-before-seen top speed of 179.6 miles per hour.
