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/projects/seagull-3-by-zx-rc-high-efficiency-3inch-bi-blade/x/19524017#/ 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/2020/02/17/fly-test-a-big-success/ Fly video demo: https://www.youtube.com/watch?v=2BCGSPec2GI If you use an SLA printer, print them up side down so it's easier to remove the supports from the convex side and polish it. For who is gonna print them with basic resins, please be advised that they will hold up well 3S battery. For aggressive fly on 4S please use abs like resins or other similarly resistant. For FMD 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. 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 ZX-RC
