Gottingen 765 Airfoil Micro Drone Propeller (39.61g thrust @ 3V)

thingiverse

The drone propeller has been designed by using the **Gottingen 765** airfoil coordinates (used on the Messerschmitt Me 163 Komet). All tests were done on the **[Drone Propeller Thrust Tester](http://www.thingiverse.com/thing:2302071)** Results can be inspected below. It was printed slowly, by using a **[0.2 extruder nozzle](http://amzn.to/2qQdFvg)** at 0.04mm layer height. The final part was cleaned using a **[Precision Knife](http://amzn.to/2pV1sGA)** After this, I then got to finish the propeller using a **[400 grit sandpaper](http://amzn.to/2pTNwic)**. These are the thrust readings for some voltage values (also visible in the pictures taken): - **1.5V** => **8.45 grams** - **2V** => **11.29 grams** - **2.5V** => **22.59 grams** - **3V** => **39.61 grams** The files I included contain all pictures relevant to the test, with 6 text files that have all the airfoil coordinates used in the build, the STL files and the SLDPRT files. If you want to play with the propeller, make sure you have a couple of **[8520 coreless motors](http://amzn.to/2qPUhi4)**. You should use the SLDPRT files, just in case you want to make your own changes to the drone propeller. **Note:** Airfoil plotted using the matplotlib library in python.
