The number of blades was your issue? So a 2 bladed semi-rigid supersonic helicopter, not so much. But I am guesssing based on your statement that a multi blade fully articulated supersonic helicopter...yes?
And leave the show alone. Neat in concept and based on a great maintenance pig of a helicopter that died a tragic death in EMS if I remember the story. But still cool show with Ernest Borgnine and multiple helicopters in it. Between it, Riptide and Magnum, what more could a kid of the 80's ask for.
