Updated the top post with Spin Brush results.
I also took that Plasma Dash armature that I rewound with 35 turns of 28Ga, and put into a shiny new Yeah Racing ball bearing motor can with some Yeah Racing thin Neo magnets. Sounds
really nice. Need to test it in a car.
Current draw on that one is only 0.58A, same as a stock stage 2, but I'm thinking it won't be performing like one.
