Computerized flight control is nothing new, but the Phantom 4 is the first Phantom to be given a pair of eyes. Among other features, these front-facing visual sensors enable obstacle avoidance during automatic return home and allow it to track a subject. It also features Vision Position, a carryover from the Phantom 3 Professional and Advanced, which provides navigation for times when GPS is unavailable and the quadcopter is close to the ground.
One area where fixed-wing planes have traditionally held an advantage over multi-rotors is performance. The Phantom 4 aims to shake off this stigma. With its Sport Mode, the quadcopter can achieve a top speed of 44.7mph. That's enough speed to take to the races or follow fast-moving subjects, such as a vehicle or skier hurling down the slopes. Since you may need to slow down in a hurry, Active Braking brings to the quadcopter to a halt much faster than drag alone otherwise would.
