Here I’ll tell you in more detail, in short, the seller sent a drone, but from the very start there was a marriage, I was only able to determine it today. Please note that the drone visited their "service", where they did not determine my problem and said that there was no marriage, as a result, they did not wait for a return. As a result, after my checks in the kit, the power adapter was not in working order, I tried to connect another adapter and it all worked, the hub started charging. In general, the toy is good, but the seller did not do well.
