In general....I would agree with MagPlug about the differences between small and large Helicopters when we talk of Tail Rotor failures.
The forces generated by the Rotor systems on large aircraft create a real design problem for the Engineers designing the aircraft.
How much Tail Fin area does it take to facilitate adequate weather vane effect for those large helicopters?
My trusty old Huey did pretty well.....the Huey Cobra derived from the Huey.....did not.
I would bet my other trusty steed, the Sikorsky S-58T, was far better than the Sikorsky S-61 or CH-53.
As in some other things in life....Size does matter along with technique.
