I ordered on aliexpress * ss. Satisfied with the set. Gave about 9 (3 batteries, 2 sets of screws, protection, 4k camera). We managed tocomnnect to the camera thanks to the application of the camera manufacturer (the name is written in the instructions). The quality of the 4k camera is excellent. It flies fast enough (my firstcompter, so I share purely personal feelings). At a height of up to 20m and a distance of up to 30m - manageable. But if it happens that there is a wind at the top, then it spontaneously gains maximum height and flies away wherever the wind wants. To resist is useless. Keep the number of the aerial platform with you, even at a distance of 200m from the trees. The first day I learned to land, sometimes thecompter fell, but he was not afraid of anything! On the second day, the wind in the upper layers carried thecompter to the poplar at a distance of 200 meters from the flight site. On a tree, the screws caught on small branches. I had to call an aerial platform under the enthusiastic views of the residents of nearby high-rise buildings. Stripped off. Gone into the wilderness. Decided not to go too high. But the 1-2m/s hurricane lifted thecompter again and took it to another tall tree, where it is impossible to fit the aerial platform. I have been waiting for a week for a normal wind that will shake the branches of a tree and I hope that thecompter will fall (fortunately, it is not afraid of falling). But in general, I do not recommend thecompter: it is not clear what emotions it brings. Either the joy of flying and video, or regret about the thousands thrown out on thecompter and aerial platforms. It was not possible to feel that you reallycomntrol it, although it was launched withcommplete calm below. - After uploading to youtube, the video lost a lot of quality, but the original source is of really good quality!
To give you a better perspective of the product, I have added some photos to my review.
