Goal
To develop a reliable variable-pitch mechanism and propeller that is (mostly) 3D printable.
Eventually I might build a full-fledged quadcopter with this mechanism.
Progress
I’ve started to design a basic rigged mechanism in Onshape. The blades are symmetrical, since I want the propeller to have the same amount of thrust up or down. I’m currently trying to figure out logistics regarding optimum part structure and the drive system.
Here are two prop blades printed with PETG:
MVP
A quick rough build of a mostly 3D printed variable-pitch prop. Version two will have significant improvements.
