Trying to clarify my understanding:

Static rollover: once CG moves "outside" the pivot point, the restoring moment present when the CG is inside the pivot point becomes a roll moment and over it goes.

Dynamic rollover: rate of roll builds in a non linear way with horizontal thrust component increasing rapidly(function of angle and collective and cyclic application); if roll not stopped before momentum carries the CG beyond the pivot point, over it goes.

In looking at the geometry of the B407 I fly (with low skids) it appears that the angle for static rollover would be extreme, at least with full fuel (1000 lbs, which sits low in the airframe). With light fuel load, CG would be higher an the critical angle would be reached sooner in the roll.
