I forgot to mention a tactic used for improving pitch stick force per G.
Where an elevator rod or wire is connected by a pulley wheel or lever
- a mass on a fore and aft lever arm from the pivot provides a turning
moment which increases with increasing g, so as to increase the reaction
to elevator control force with g. This was the tactic used on the
Spitfire, if I remember....
There's another mass that is not structural like surface balances.

That's called a bobweight, and it's to give the pilot some sense of
the stress he's putting on the airframe. Many current aircraft use it.
Even the Cessna 185, IIRC, has it. See a service bulletin regarding
the bobweight on the Citation:
