Most PCBs, even really cheap ones, are made from FR-4, which is a very robust fibreglass. It’s would be a pretty decent choice for drone components in general.
Not drones, but Carl Bugeja on YouTube makes some fascinating machines almost entirely out of PCBs (although he uses a lot of flex PCBs, not just FR-4).
Is PCB as the structure a new thing or has that always been a thing?
There are a few PCB drones out there.

I’ve seen some of his videos and thought it was a relatively new service offered by these custom pcb companies.
