TOROIDAL PROPELLER on a DRONE, DIY 3 D printed

A very simplified 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 nor optimised. The design was a quick 5min design. It has just the basic shape of a toroidal propeller and was formed in a way so it can easily be 3d printed. It wasnt expected that the 3d printed propeller would survive a flight test. Because of the designs simplicity, it cant serve for a realistic comparison between toroidal and conventional propellers in terms of performance, acoustics, efficiency, etc. 0:00 Design 0:10 Slicing 0:15 3D Printing 0:36 Close up of the finished drone 1:04 Flight with 3d printed toroidal propeller 2:52 Flight with 8 blade propeller Drone setup: 3d printed toroidal propeller: movr5tpr1 fm2004t 1800kv toroidal propeller fettec aio 35a 6s550 90, 95c 8 blade propeller: movr5tpr1 fm2104m 1800kv 76mmx8 hqprop fettec
