Describe your use case
When the balanced reaction wheel model is used, the wheels' constant mass and inertia contributions are ignored under the assumption that they are absorbed into the hub's mass properties. Therefore, it is up to the user to augment the hub's mass and inertia with the reaction wheel's mass properties. This is subtle and can often be missed because, even if the user sets the mass of the wheels as non-zero, they will never get used.
Describe alternatives solutions you've considered
The current model is valid but can be misleading due to how subtle the assumptions are included. From a coding perspective, standardizing this behavior would be preferable and lead to less confusion.
