S4094 E-flite UMX ASK-21 Airfoil Micro Drone Propeller (39.17g thrust @ 3V)

thingiverse

I designed a micro drone propeller by utilizing the S4094 E-flite UMX ASK-21 airfoil, which underwent rigorous testing on the Drone Propeller Thrust Tester. The part was printed at a slow speed with a 0.2mm nozzle at 0.04 layer height and then thoroughly cleaned using an X-ACTO Knife. Next, it was carefully sanded with 500 grit sandpaper to achieve a smooth finish. Below are the thrust readings for various voltage values: - At 1.5V, the thrust reading was 13.59 grams. - At 2V, the thrust reading soared to 20.44 grams. - At 2.5V, the thrust reading climbed to an impressive 31.19 grams. - At 3V, the thrust reading reached a remarkable 39.17 grams. The accompanying files include all the shots taken during the test, along with six text files containing airfoil coordinates used in the build, STL files, and SLDPRT files for making custom changes to the propeller. For those looking to have some fun with this propeller, acquiring a set of 8520 coreless motors would be an excellent idea. To make modifications or create new designs, users should utilize the SLDPRT files.
