Sky has invested $1m (£750,000) in the Drone Racing League (DRL) in a deal to broadcast the thrilling US competition on Sky Sports Mix.

Broadcast as 10 one-hour episodes starting in October, the series will feature five races from the 2016 DRL season and a winner-takes-all World Championship which will crown the year's best drone pilot.

The high-octane races, in which competitors fly the radio controlled machines through futuristic obstacle courses at speeds reaching 80mph, have been compared to bringing video games to life.
