The UH60 was a helicopter out of my Father's generation. I had pretty much been indoctrinated to be part of the Sikorsky family as he always talked shop with me. My understanding of the canted tail rotor is they did it for the "free" lift. Years later Sikorsky and Boeing were team mates on Comanche and my dad was discussing the competition with his colleagues at Boeing. The Boeing UTTAS entry was about 400lbs short of the lift spec requirement. Their smart people did an analysis of the Sikorsky entry and figured we were short too. They neglected the canted tail rotor which added about 400 lbs of lift at max gross weight.

The lift was not totally free as it mucked up some of the handling qualities. But, that made for some interesting work for him as he was a flight controls guy.
