Thinking about it, we must apply some reverse aileron to stop the roll. We don't just let go of the stick. It will not be hard to test!

Now it makes sense to me that the low inertia makes for the very crisp axial roll maneuvers. It also makes the term roll damping make sense. The damping, in a basic physics sense, would control our ability to stop the roll without overshooting or oscillating about the stop point.

Is "roll damping" used in a generic sense to refer to aerodynamic drag in a roll direction?
