RC Plane Propeller

thingiverse

Here is a printed prop that I designed with a key way so that the pieces slot together easily. Its rough looking but its printable and it works! Due to printing the prop side ways, It has high tensile strength. Although I wouldn't use these props on an expensive easy to break plane! You'll find out very quickly whether or not your print is going to hold or not. Roughly 1 out of 6 of mine exploded,or sheared on take off. But if it can handle take off then your pretty safe to fly! Instructions The tricky part is getting the area and pitch of the blade right to pull it through the air. This would depend allot on what motor setup your running. A Low speed high torque configuration is probably more suited for printed props as they tend to flex and some times shatter at higher speeds under full load e.g. Take off. This creates allot of noise (which actually sounds kinda neat!) You get a buzzing humming bird kind of sound. Its ideal for my 3d plane (its a foamy) as it designed for doing low speed tricks, (Knife edge, Prop hang etc).Also buzzing sound is a great indication as to how much trust I'm giving it in the air. IMPORTANT: A dab of Super glue on the Inside overhang lips once its locked into position is a good idea. At high speed they tend to start tearing away from the center with out any support.
