- Underestimate of reaction wheel mass: The maximum revolution rate underestimates the angular momentum the wheel needs to remove from the rocket.
- Overestimate of reaction wheel mass: The mass ratio (intentionally) overestimates the necessary inertia ratio, as described.
- Underestimate of reaction wheel mass: The radii of the wheel and rocket are assumed to be equal; however, the wheel's radius is necessarily smaller.
Currently, "Big Red" is the expected test vehicle (being 6" diameter), with a wet mass of 21 pounds.
