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

My campaign on Indiegogo for high efficiency 3 inch bi-blade finally started!! Please support me and receive your propellers too: https://www.indiegogo.com/proj...

Another prototype propeller from my project. These propeller can make your 3 inch drone fly long! I share this version which are those which forgives more 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/

The thickness of this model is optimized for FDM users, I added a specific design that can be printed with 0.4 nozzle and it will not miss the thin parts of the original design. I uploaded only CCW version but you can just mirror it to have CW version.

These propellers are not intended to fly with ultralight 3inch quads. At least I didn't test them yet.

If you like it and you want to get more and newer propellers you can subscribe to my newsletter: http://zx-rc.blog/

I will share most of my designs. Cheers
