SASless Question being....if a full right pedal application equals or exceeds the Turning Moment of the Main Rotor system....one could test various techniques to control the spinning of the aircraft.
Check tail rotor blade pitch min. angle of attack acc. AFM
If it's 0° or even negative, I'd say full right pedal would result in zero "counter thrust",
e.g. same "counter torque" as if tail rotor fell off.
