3 inch bi-blade propellers for FPV drones with Ø5mm mounting hole - Proto D5

thingiverse

My campaign on Indiegogo for high-efficiency 3-inch bi-blade is now live! 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 has been completed. These propellers will make your 3-inch drone fly longer! I'm sharing this version, which is more forgiving of defects in 3D printing. You can find more details about the propeller in this post: http://zx-rc.blog/2020/02/17/fly-test-a-big-success/ A fly video demo is available at https://www.youtube.com/watch?v=2BCGSPec2GI If you're using an SLA printer, print the propellers upside down to make it easier to remove supports from the convex side and polish them. For those printing with basic resins, please note that they will hold up well to 3S batteries. For aggressive flight on 4S batteries, use ABS-like resins or other similarly resistant materials. I've also added a specific design for FMD users that can be printed with a 0.4 nozzle and won't miss the thin parts of the original design. If you like this propeller and want to get more and newer designs, subscribe to my newsletter: http://zx-rc.blog/ I'll be sharing most of my designs. Best regards, ZX-RC
