Toroidal Propeller Pack

I found the Ultimate Propeller Launcher and got it up and running, but found the propeller underwhelming. There is an option from someone else for a toroidal prop, but there is only one option. I've always wondered about the diminishing returns on blade number and size, so I have a made a ton of sizes to test our what might be these best option.I've got various sizes at 100, 140, 180, 220, and 240 mm widthas well as different blade counts for each, at2, 3, 4, 5, 6, 8, 10, 12, 16, and 20 blades for each size.The blade is 1.2mm thick, so it can be printed at 0.4mm with 3 passes, or 0.6mm with 2 passes.If you do any comparisons, please let us know what you find flies the best!Please do note that I have not tried all of these combinations and don't know which will or will not work well. I've done some of the 140mm 3 and 4 blades and they work well. I just printed a 220mm 6 blade and couldn't get up enough momentum to get any height.
