The Chinese company DJI is conquering ever new heights in the miniaturization of its drones. A new big step on this path was the folding Mavic Mini weighing just 249 grams, which we all knew about the day before. Due to this weight, he does not even require registration with the US Federal Aviation Administration.
When folded, the device occupies only 140 × 82 × 57 mm (and when unfolded with propellers - 245 × 290 × 55 mm). Despite the miniaturization, the device retained the main features of the more advanced DJI drone - the Mavic Air (it weighs 430 grams), and in some aspects even surpassed it. For example, if Air provided up to 21 minutes of flight, then Mini is able to boast of all 30 minutes.
It is worth mentioning, however, that on the product page there are two Intelligent Flight Battery: lithium-ion weighing 100 g and a capacity of 17.28 Wh; the lithium-polymer weighing 50 g and more than half the capacity - 8.36 Wh . It can be assumed that the weight of 249 g is indicated taking into account a lighter battery, and a flight time of 30 minutes - for a heavier one.
At the same time, a full-fledged 3-axis stabilizer and the ability to fly up to 4 km (in the American FCC mode) or up to 2 km (in the European and, accordingly, Russian MIC / CE mode) migrated to the miniature drone. The camera and sensor also remained almost the same: the Mini can offer a 1 / 2.3 ”CMOS sensor with a resolution of 12 megapixels, a lens with a viewing angle of 83 ° (24 mm in 25 mm equivalent) and an f / 2.8 aperture. Even the focus is not fixed, but variable, from 1 m to infinity. There are collision protection and positioning sensors, as well as a GPS receiver.
There are, however, very noticeable shortcomings: in sports mode, the Mavic Mini can fly at speeds up to 13 m / s against 19 m / s in the Mavic Air; in addition, the maximum video resolution is 2.7K (2720 × 1530 at 30 frames / s) or 1080p (1920 × 1080 at 60 frames / s) with a video stream of only 40 Mbps. For comparison: Air supports 4K / 30p at 100 Mbps. HEVC support could somewhat compensate for the low bit rate, but it is not there either.
DJI also significantly reduced its photo capabilities: for the first time in the Mavic family, the Mavic Mini does not support shooting photos in RAW format - there is only JPEG support. Obviously, the manufacturer is afraid of competition within its own family of quadrocopters and artificially limited the photo and video capabilities of the device, because today even inexpensive smartphones can boast of RAW or 4K video.
Therefore, it is not surprising that DJI focuses on family use and ease of shooting, as well as stickers for painting the body with markers. The DJI Fly mobile application contains various templates that allow you to create great videos with one click (for example, “Droni” (selfie from the drone), “Circle”, “Spiral” and “Rocket”). Even beginners without video editing experience will be able to make workshop videos. And the Fly More kit includes plastic protection for 360 ° propellers, which allows you to safely remove indoors.
A basic set of a drone, a controller and one battery costs $ 399 in the United States, and the Fly More set, which includes 3 batteries, a charger for three batteries, propeller protection and a carrying bag costs $ 499. The company also released a number of accessories.
