What is the difference between multi-rotor drones and other drones?

 Usually the number of rotors of a drone is positively related to its stability.

  • Dual-rotor drone

Disadvantages: The flight stability is low, and it is easily affected by the weather, and the reliability is relatively low.

And can only fly in two directions towards the motor, giving the control algorithm more reliance.

The structural layout of the UAV needs to be more rigorous, the distribution range of the center of gravity should be more accurate (it needs to be located in the center of the connection between the two motors), and the modification is relatively difficult.

Advantages: Longer battery life and higher efficiency since only two motors are required.

  • Tri-rotor drone

Disadvantages: In the outdoors, due to the wind, the stability is still not enough, the reliability is still not high; and the speed and performance are lacking.

Advantages: It can control more directions of flight than dual-rotor UAVs and can withstand larger loads.

  • Quadcopter drone

One of the most common drones on the market.

It achieves a better balance of price, performance, stability and flight time.

There is a greater demand for geographic mapping, aerial photography or toy drone industries.

  • Hexacopter drone or above

Disadvantages: More rotors lead to higher power consumption, shorter battery life, and larger size than other drones.

Advantages: more stable, with a larger load capacity, high safety.

Generally used in the agricultural field, it can be used to carry and spray pesticides in large areas; it is also a new development trend in the field of express delivery.

MEANING OF TOYS

Growing up in a city world-renowned for making toys , toys used to be segmented in my eyes. On the one hand, as a child, those brightly colored little things that can move, sing and dance attract the eyes to the eyes; on the other hand, seeing the toy factories that can be seen everywhere, people make and sell toys, and make a living from it. Now, as an individual who has stepped into the toy industry and intends to stay in, toys show me another side of it. It is no longer a simple cute little thing, nor is it a component on a cold assembly line, but the beauty of the adult world, adding imagination, adding perfect eye-catching colors, and showing them to children.  Children are attracted by these fun and cute things. Through these toys, they will initially touch and explore life in the adult world, which will be the best beginning or learning stage of their life. Of course, for now, toys are not just a proper noun for children. Various adult decompression toys, models and motorized to

BUZZ KIDS DRONES F188

Image
 As a brand focusing on the field of toy drones, BUZZ KIDS DRONE is undoubtedly at the forefront of exploration and development in the field of toy drones.  The F188 series drones are already comparable to professional drone products, and are recommended for customers with sufficient budget and higher photography requirements. The drone is claimed to have 6K-level pixels, which has attracted consumers looking for an entry-level photography camera drone focused on personal use. Because compared with DJI's professional-grade expensive drone products, if your positioning is only for shooting works that are not very difficult, this drone can fully meet your needs. In addition, it has other features: (1) Using GPS and optical flow positioning makes the UAV not easy to yaw. (2) GPS intelligent return, low battery and out-of-control return add a guarantee to the safe flight of the drone. (3) Recognition and taking pictures, intelligent follow-up, etc. are completely satisfied with the fun
