S-92 Fathawk
The S-92 was initially conceived as an extension of the Blackhawk line. As such, the dynamic components were designed to be back fitted on to improved versions of the Blackhawk. This was, in principle, a sound plan until the empty and all up weights of the S-92 grew to the point where adjustments to the basic rotor designs were required. The S-92 is still a fine aircraft. It is just a like weak in the growth department.
