This project is based on a 1935 patent by Robert Stanley, and was created for a design competition "Mechanical Marvels" on Printables.com

Great. Variablepitch prop show. I take it that a variable pitch prop is basically if the same construction technique.

Bravo ! Quelle complexité ... je n'ai franchement pas compris comment ça marche. On dirait qu'il y a des pertes considérables, mais je viens d'apprendre que le brevet de Stanley a effectivement été appliqué dans des hélices produites en série.

I can´t grasp my mind around how are you able to control the blade pitch angle while the propeller is turning EDIT: I now understand it. It´s incredibly amazing
