RC Plane Propeller

thingiverse

Designed with a key way, this printed prop easily slots together and boasts high tensile strength due to printing sideways. However, it may not be suitable for expensive planes that are easily broken. Roughly 1 in 6 of your props could fail during take-off, but if they survive, you can expect smooth flight. The key is getting the blade area and pitch right depending on motor setup. A low speed, high torque configuration is ideal for printed props as they tend to flex and break at higher speeds. This creates a buzzing sound that indicates trust in the air. Don't forget to apply super glue inside overhang lips for support at high speeds.
