Starspinner is a project that allows to modify the 84 RPM goBILDA Yellow Jacket Planetary motor to create either 4200 RPM or 8000 RPM. The entire conversion happens inside the planetary housing, allowing you to mount the motor as you would with a standard goBILDA motor. It works by reversing the effect of some stages inside the planetary gearbox.
