Yes that is why a proper equation uses "moment of inertia" not just the mass. That doesn't seem to be properly accounted for in the Supercool version. Because a props mass is closer to the center VS the heavy outer rim of a gyroscope I suspect the Supercool formula exagerates the force by a considerable amount. While the effect is stronger than someone had posted earlier, I don't think it is nearly that strong. The site referanced in SSW is spot on to use the radius of gyration instead of the total radius to figure out the moment of inertia.
