Just wondering---some tall skyscrapers have spring dampened sliding weights
on the top floor to null out swaying motion caused by wind forces. A form of
yaw control.
Could an added weight in the rear used for traction enhancement be similarly
used for yaw control if it was allowed to oscillate side-to-side
(constrained by springs) at a certain frequency ?
A "damper" of this type would not require any power input. Design weight and
springs for a resonant frequency related to yaw rate?
