On May 25, 2016, Xiaomi released the millet drone on the Xiaomi live broadcasting platform and also conducted a test flight on the drone. The millet drone was built by Feimi Technology, a subsidiary of Xiaomi's ecological chain. From the perspective of price allocation, the millet drone is still a cost-effective route. The 4K version is only priced at 2,999 yuan and the 1080P version is priced at 2,499 yuan.
What we got this time was the 1080P version of the millet drone. The packaging box of the millet drone was very large. After opening, we could see a main body of a millet drone, a 1080P drone PTZ camera, and a Drone remote control, a USB data cable (Android), 8 self-tightening propellers, 4 drone protection frames, a battery, a charger, a wrench, a screwdriver, and 9 screws.
The aircraft of the UAV drone has a white color scheme as a whole, the top of the aircraft is very simple, the traces of screws are not visible, and the center is a logo of a millet that can be loaded with four self-tightening propellers (two positive + two reverse). Compared to the top, the bottom of the aircraft is covered with screw holes, and the bottom central buckle is used to mount the drone PTZ camera, using a 4x Cortex-A7 CPU. The left and right landing gear can rotate more than 60°.

Aircraft parameters:
Wheelbase: 434 mm; flight limit distance: 500 m; flight limit height: 120 m; flight time: 27 minutes; wind resistance rating: ≤ 4; maximum ascent speed: 6 m/s (novice mode 4 m/s); Falling speed: 1.5 m / s;
In fact, the installation process of the millet drone is not complicated. Put the battery and drone camera into the buckle of the aircraft, and then screw on the four self-tightening propellers, and finally fix the four drones with screws. Shelter can be. The whole process of installation is very short. Even a beginner of a drone can complete the installation in 10 minutes.
After installing the millet drone, due to more self-tightening propellers and drone protection frames, the size of the whole machine will appear larger.
remote control
The shape of the remote control is similar to most drones. It is equipped with a PCB array antenna, a dual antenna design, a built-in mobile phone holder, which can be folded into the remote control and supports Android/iOS devices.
Remote control parameters:
Operating frequency: 2426.5 MHz ~ 2461 MHz; Control distance: 1000 m; Transmitting power: < 20 dBm; Sensitivity: -101 ± 2dBm;
Drone camera
The design of the head camera of the millet drone is integrated. The head and the camera are closely integrated and cannot be disassembled.
PTZ camera for the three-axis image stabilization design, self-stabilizing angle: pitch -120 ~ 35; roll -35 ~ 35; orientation -65 ~ 65;
Parameters of the camera (1080P version): Lens angle of view: 104°; aperture: F/2.6; camera focal length: 4.2 mm (23 mm equivalent); sensor: 1/2.3; camera pixel: 163.5 million; ISO range: 100 - 3200 (Video); 100 - 1600 (photo); Shutter speed: 1 / 6 seconds ~ 1 / 8000 seconds; Video: 1920 x 1080p 60fps; 1280 x 720p 120fps; Memory Card Type: Micro Card (Supports Class10/U1 or more) 8 ~ 64G; Support working frequency band: 5GHz;
Charger and battery
The charger and battery use skin-like materials and the surface is smooth. The battery can be easily placed into the aircraft. The millet drone has a battery capacity of 5100 mAh / 77.52 Wh and weighs 450g. The output specification of the charger is 16V/2.9A, and the rated power is 46.4W; the wiring of the charger is very thick, similar to the wiring of the computer power supply.

Protection rack
Propeller and protection frame
The self-tightening propeller has a length of 10 inches and a pitch of 4.6 inches . There are two types of self-tightening propellers . The two positive and negative propellers are located on the diagonal of the aircraft. The self-tightening propeller knob is made of metal.
The protection frame is made of plastic material and has a certain elasticity. The single weight is 22.66 g and can be protected by 140° of the outer ring.
Screwdrivers and Wrenches
Finally, let's take a look at the comparison of the parameters of the UAV drone and other UAVs. In the follow-up, we will conduct horizontal reviews on several drones including the Xiaomi drone and the Dajiang Elf4. Interested friends please pay attention. Our follow-up report.
