Zero Zero Robotics’ V-Coptr Falcon camera drone has only 2 rotors rather than the normal 4 but that’s not what makes it such a standout. This thing is all about flight time. 50-minutes. About twice what similar competitors can claim. So that’s a big deal. The camera captures 4K video at speeds up to 30fps and video transmission boasts a range of 4.3 miles. Object avoidance, auto-homing—all the features you’d expect and then some.
