HAM-STD HS1-404 Airfoil Micro Drone Propeller (41.87g thrust @ 3V)

NOTICE: Very thin airfoil requires great printer calibration skills, so print only if you're confident. I designed the propeller with the HAM-STD HS1-404 airfoil. All tests were conducted on the [Micro Drone Propeller Thrust Testing Jig](http://www.thingiverse.com/thing:2302071) (results are below). I printed this part using a slow setting, aided by a 0.2mm nozzle at 0.04mm height per layer. I cleaned the final part using a [Precision Knife](http://amzn.to/2pV1sGA). Next, I sanded it with a 400 grit sandpaper. Here are the thrust readings for several voltage presets (also visible in the pictures taken): - **1.5V** produces **11.91 grams** - **2V** results in **22.46 grams** - **2.5V** yields **33.47 grams** - **3V** produces **41.87 grams** The files available for download include all shots taken during the test, along with six txt files containing airfoil coordinates, STL files, and SLDPRT files. If you want to have fun with this propeller, consider getting a [8520 coreless motor](http://amzn.to/2qPUhi4). Use the SLDPRT files if you'd like to make your own changes to the drone propeller. **Note:** The airfoil was plotted using the matplotlib library in python.
