In the first version of WinDIY I installed a pitch actuator. With this it was possible to adjust the angle of attack of the wings.

Unfortunately, the build was very complex and large. (You can find more information here: )

So I want to use a different system for the new version. I'm currently working on a 3d printed worm gear. Three of these should then be installed in the hub of the turbine in order to adjust the blades directly.

You can see the working prototype in the video below. This construction has several advantages:

Here is the promised video and a few pictures. :)
