TOROIDAL PROPELLER on a DRONE | DIY 3D printed

Nothing was calculated. It surely can be optimised a lot. 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 as comparison 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 aio 35a 6s550 90c Toroidal propeller diameter: 90mm / Drone weight without propeller and battery: Drone weight with 3d printed torodial propeller and without battery: 145g Drone weight with 8 blade propeller and without battery: Toroidal propeller weight: 8 blade propeller weight: Battery weight:
