A sleek new design with magnesium unibody construction, obstacle avoidance sensor, dynamic range enhancing video modes, and a two-point-of-contact gimbal mount are just some the featuresDJIhave introduced with thePhantom 4 Quadcopter. Thanks to improvements in efficiency as well as its intelligent power management system, the quadcopter boasts up to 28 minutes flying time. Its camera shoots DCI 4K (4096 x 2160) video at 24/25 fps and UHD 4K (3480 x 2160) at up to 30 fps. There is also a 120 fps mode in 1080p resolution for slow-motion effects. The camera will also take 12MP still photos in either DNG RAW or JPEG, with single shot, HDR, burst, and time-lapse modes to choose from.
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.
