Usually for unusual attitude Sim checks my control input is inversely proportional to the amount of pressure felt through the control yoke - sometimes resulting in the airspeed briefly exceeding Vne prior to coming climbing out of the parabola. The idea in mind is to be gentle and not overstress the airframe, especially above Vma.
If the amount of force applied resulted in disconnection of a quasi "interconnect unit", could this be an indication that excessive force was being applied?
