The inaugural World Drone Racing Championships (aka Drone Worlds) is the culmination of over a year’s anticipation for a truly global, world-leading first-person-view drone racing competition, and expectations were high. The event was held on Kualoa Ranch in Hawaii on the island of O'ahu, the spectacular setting which has served as the famous backdrop for Jurassic Park and many other films. The epic volcanic cliffs, which encircle the race course, create a rather dramatic backdrop.
