It is amusing insight to human perception that some of the pilots were not happy when the RAE did address the Longitudinal Instability of the early marques. Some pilots actually felt the bob weights took away the maneuverability.
All they did was increase the stick force gradient to make the longitudinal control heavier. Bob weights do not effect the dynamic pressure acting on the control surface or even the hinge coefficients.
Bob weight force is simply added to the force gradient already present to achieve a higher stick force per G resulting in the perceived stick forces achieving the minimum standards.
