I've purchased a hero 3+ black edition and hope to video pro sized RC helicopters. I will mount the camera on my hat and want to be able to later analyze the flight. The average size of the helicopter is 36 inches long and 12 inches tall with a rotor disc of five feet. For safety, distance from camera is 30 feet and greater. I am now learning the settings available, any suggestions to get the best video would be appreciated.
