Well, in response to the reason why the H60's T/R is canted up, it is to help with the CG situtation by supplying 2.5 % of lift of the helicopter at the aft end. And the reason why helos hover left side low (Bell, Sikorsky etc) as opposed to right side low (Russian, French) in a no-wind condition is do the correction applied to counteract translating tendency(to oppose the drift from the tailrotor and torque pushing the helo sideways.
