And although I broke it for the new year, it's my own fault - I launched it from the balcony and it hit. Hit the wall. There was no external damage. Launched from an extended board). He took off, but he was led and he fell into the snow and hit the metal fence before that. As a result, the "leg" (more precisely, the mount-hinge) broke. I ordered parts. It's a little hard to understand in some places, but overall it's okay. I had to buy a set of screwdrivers - a long hexagon. Plus, for fixing, I had to remember how to use a soldering iron. Inside on the controller, all contacts are soldered. On the Internet there is a detailed video with the disassembly of this unit. After repair, it has been tested several times already. Flies like new.
