A flying control mass balance weight
- keeps the control surface C of G as close to the trailing edge as possible.
- tends to move the control surface C of G close to the hinge line.
- tends to move the control surface C of G forward of the hinge line.
Explanation
Mass balancing adds weight forward of the hinge to shift the control surface's centre of gravity toward (onto) the hinge line. This prevents inertial coupling between bending/twisting of the structure and the control surface, which is the cause of flutter. Leaving the C of G aft of the hinge would leave the surface prone to flutter.

why? shouldn't be C?

I think C. tends to move the control surface C of G forward of the hinge line.
it is correct.
it is correct.
