3 inch bi-blade propellers for FPV drones with Ø5mm mounting hole - Proto D8b

thingiverse

My campaign on Indiegogo for a high-efficiency 3-inch bi-blade has finally taken off! Please support me and receive your propellers as well: https://www.indiegogo.com/projects/seagull-3-by-zx-rc-high-efficiency-3inch-bi-blade/x/19524017#/ Another prototype propeller from my project is available. These propellers can make your 3-inch drone fly for a long time! I'm sharing this version, which forgives more of the defects of 3D printing. You can find more details in this post: http://zx-rc.blog/2020/02/24/the-best-3d-printed-propellers-in-the-world/ https://youtu.be/e_giGAwieR0. The thickness of this model is optimized for FDM users, and I've added a specific design that can be printed with a 0.4 nozzle without missing the thin parts of the original design. I only uploaded the CCW version, but you can easily mirror it to get the CW version. These propellers are not designed for ultralight 3-inch quads; at least, I haven't tested them yet. If you like this and want more and newer propellers, you can subscribe to my newsletter: http://zx-rc.blog/ I will share most of my designs. Cheers, ZX-RC
