Aerial footage from the final day of the Rip Curl Pro was recorded using GoPro cameras attached to remote control quadrocopters. The video includes shots of Kelly Slater, Mick Fanning, and others. Quadrotors, also known as quadrotor helicopters or quadrocopters, are remote control aircrafts that are propelled using four separate rotors. Congrats to my boy Parko on the Bells Beach win.
