stall and spin (7):

Feedback loop on yaw rate for flat spin.
|
|
Accelerates the yaw rate when stalled, up to a self-maintained flat spin (like a dead leaf).
|
|
r-aero-rad_sec with non-zero coefficients mainly sets the max yawing rate, if attained.
|
|
The coefficients set the yaw moment, thus the speed too, and the flatness of the spin.
|
|
Too great coefficients give an divergent effect and a non-recoverable spin.
