The Blackhawk tail rotor is canted 20 degrees. At 20 degrees, a full 34% of the thrust go to lift while only a 6% reduction in anti torque thrust is realized. The Blackhawk literally holds up its own butt. This provides for an increase in longitudinal CG range. The H-53E Tail rotor is also canted 20 degrees. On a negative note, canting the tail increases the complexity of the flight control system as revealed by a quick peek at the Blackhawks flight control mixer unit.
