The Hover Camera Passport foldable drone made quite the impression when it first launched a little over two years ago, and then it received a major update in April last year, which added a smartphone-free mode that automatically tracks and records its owner. Save for the rumored Snap acquisition deal (which Zero Zero Robotics still denies today), we had barely heard from the drone maker since then, but today it's back with a surprise announcement: The launch of its second selfie drone, Hover 2. As you'd expect, the Hover 2 has inherited all the best bits of the Passport, especially its small foldable form factor, sturdy carbon fibre cage enclosure, Qualcomm Snapdragon processor (model not specified but it's "four times more powerful than" before), 4K 30fps video capture, face tracking and body tracking. The two drones look similar from afar, though the newer model benefits from more than double the original flight time, jumping from a mere 10 minutes to 19 minutes (but maximum flight time is 23 minutes; more on that later). This may explain the heavier weight of 490 grams or about 1.1 pounds -- almost twice as much as before. When switched on, you'll notice a new major feature on the Hover 2: Its swiveling "Optical Radar" that pops out of the top of the body.
