⚠️ I'll say this again, I'm not an engineer and there are probably better ways to do this. The method demonstrated is certainly not as scientific as I would like, but I think it's a fairly accessible way to design a prop and also be able to make small adjustments to refine it. If you want to know more about why the design is the way it is, I also urge you to check out my previous videos on the Toroidal Topic:

⚠️ If you're completely new to Fusion 360, you might want to start with one of my older Fusion 360 tutorials (with much worse audio) before trying to take-on the task of complex lofting to create a toroidal propeller, so have a look here at how to make a duct instead:
