Most used props for racing quads, are 5 inches diameter, and the pitch is between 4.2 and 5.2 inches.
Aisak, Thank you! Yes! I was looking at the Azure Power 5045s (5 inch, 4.5 " pitch). The propeller that I am looking to make is 50 mm or smaller. My first practice run was 15 mm diameter, too small for any quadcopter in existence.
