Drone racing exists in some still-being-defined space between eSports and motorsport: those are real vehicles zipping through real space at blinding speed – it’s just that the pilots are sitting somewhere else, in chairs and wearing video goggles. From its hobby days, when enthusiasts actually developed some of the key technology that makes the racing possible, it has suddenly become a sport with rules, international competitions and even a few pro players. It’s also rapidly evolving, with the debut of the new X Class category offering metre-wide drones that spectators can more easily see (and hear). There’s no X Class in the Drone Champions League leg at Lake Zurich in Switzerland, but there will be, for the first time, a separate contest between robo-drones, which fly the course autonomously. If you want a look at it all, there’s live coverage from Zurich on Sky Sport 1 from 6am on Sunday.
