In addition to increasing the available C of G range Canting the Tail Rotor moves the bottom of the tail rotor tip path plane higher from the ground. In view of the additional flight control complexity and resulting icreased weight I wonder what drove the Engineers to adopt this configuration. Was it:
1. Increasing the C of G range,
2. Providing adequate tail rotor authority and still meeting a Design Spec (Mil or other) regarding Tail Rotor/Ground Clearance?
Perhaps John can provide some insight.
