In principle the all of the dynamic components on the S-92 were designed with the capability for being back fitted onto Blackhawk models. Operating RPM was increased 5% from the Blackhawk’s 258 rpm to allow for some portion of the increase in required ESHP. Other configuration changes were required to accommodate the relocation of primary servos. Some changes were required as a result of the S-92’s weight growth from its proposed 1993 MGW of 22220 lbs. to it present gross weight of 26500 lbs.
