The 42 and 90 degree gearboxes were upgraded to the 212 series. I don't
remember whether the tailrotor itself was enlarged but I think it was,
because it was definitely drawing more power.

Thanks for that. I know the tail rotor changed sides.

Question is did it get bigger or broader when you got to the S model.
