The real test on whether or not that design is the “Cat’s Meow” is how fast Bell and Sakorski have copied it...... NOT.
Sorry to burst your bubble, but 'Sakorski' has copied the compound blade concept.
They called it the X2, but cleverly hid their involvement in the project by calling it a 'Sikorsky'.
And it is the fastest damned helicopter in the world.
You mean like Sikorsky's S-97?
