Copy and pasted from the introduction of above document:
Here I present OpenWheel – my efforts at lowering barriers of entry into the world of high performance flywheels on standard (non-Eclipse) OFP cages. That means working with DC brushed motors, and a 2mm shaft. This project was originally motivated by cost, but through my experimentation I quickly found that I could also get superior performance to commercially available machined wheels.
The results, for those who are as impatient as me: 150 fps through a Morpheus guide on OG Fangs.
Everything is in the document. I can't stand the formatting in forums and uploading each figure individually, otherwise it would be here as well.
