My campaign on Indiegogo for ultra-efficient 3-inch bi-blade just took off!! Please back me and claim your propellers right away:\r\nhttps://www.indiegogo.com/projects/seagull-3-by-zx-rc-ultra-efficient-3inch-bi-blade/x/19524017#/ \r\n\r\nAchieving top-notch results for this ambitious project to create highly efficient propellers for 3-inch power drones has been a game-changer. You can't find such high-quality products commercially anywhere.\r\nThese prototypes aren't perfect yet, but they fly exceptionally well. \r\nYou'll find more details in this post:\r\nhttp://zx-rc.blog/2020/02/12/exciting-first-test-round-up/\r\n\r\nIf you're using an FDM printer, print them with small nozzles so you don't miss the thin parts and later polish carefully for maximum efficiency. An SLA printer would be ideal.\r\nPrint upside down to make it easier to remove supports from the convex side and then polish.\r\n\r\nWant more cutting-edge propellers?
