The present invention is an electric propulsion motor that can be used to propel air, land, and sea vehicles consisting of a gyroscope's flywheel that has been split into two counter rotating sections, perimeter and hub, each section containing spokes that are shaped to produce thrust when rotated, a stator with individually controlled field coils located on its inside and outside diameters, permanent magnets integrated into the flywheel sections proximate to the stator's field coils, and a bearing system to support each flywheel section. The invention is self-contained needing no external propulsion or drive means, self-stabilizing due to the gyroscopic forces created by its spinning hub and perimeter flywheels, thrust producing because of the shape of the spokes of the two flywheels, and rotational torque cancelling with counter rotating flywheel sections. A Chimara Effect is created that both stabilizes and propels the vehicle.
