A very simple version of a toroidal propeller for a drone. FDM printed with PETG. The propeller wasnt balanced nor cleaned after the print.
This is not a scientific test. Just a quick DIY approach. Nothing was calculated.
It surely can be optimised a lot.

For people not familiar with this type of drones:
These are selfbuilt.
You cant simply buy it in a store.
Used parts are mostly written in the title.
You dont learn to fly them in a week. It takes months/years.
Researching is a constant part of this hobby.
Im flying them manually in acro mode which means no gps, no self stabilization, etc.
