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

thingiverse

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#/ This are the best outcome at the moment of an ambitious project of creating some very efficient propeller for 3 inch power drones. Commercially you can't find almost anything. These are not perfect yet but they can totally fly. You can find more details in this post: http://zx-rc.blog/2020/02/12/exciting-first-test-round-up/ If you are using an FDM printer better print them with small nozzles so you don't miss the very thin parts and later polish carefully the surface so you get the best efficiency out of a smoother surface. If you have an SLA printer it would be the ideal. Print them up side down so it's easier to remove the supports from the convex side and polish it. 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
