Nick,
This right rapid roll is not happening because you forgot to mention the counteracting moment of the lateral left vector of the mainrotor thrust to the CoG. In other words, if you position the Total thrust in the centre of the M/R hub, which is, in my opinion, the right place to put the Total Thrust, and it tilts to the left (as in Arm's picture) you have to consider all the forces that can be vectored from this Total Thrust force and and their arms to the CoG
