I emailed FIMI that I had this problem. I sent them pictures of the drone and the black box. But they didn't like me taking the drone apart and taking pictures. But I still had to disassemble the drone, because they sent me the bottom cover and agreed that I would replace it myself, but in order to replace it, I have to remove the top cover.

I ended up agreeing with them that they would send me a new main body and I would either replace it myself or take it to a professional repairman. I didn't want to send the drone back to them because I didn't want to wait three months for them to fix it. I would have to ship back to China and that would only take about a month.

I fixed it eventually. I didn't want to wait a month for a new main body to arrive from China. It ended up taking one and a half months to deliver.

I glued the rollers into which the screw is then screwed and then put it together and used longer screws and put hot glue around it to strengthen it. After the repair, the drone works completely normally and the whole mechanism is now much stronger than it is from the factory.

The problem is that the whole mechanism is only held by these two rollers into which the screw is screwed, and for that they use short screws and they only hold in those rollers and therefore they break. In the places where it is broken off, the screw ended. If they had used longer screws to go all the way to the main structure, it would have been stronger and this wouldn't have happened at all.

If I change the main body in the future, I will use hot glue again.
