The normal S-76 sits at +8 degrees nose up at aft CG, and 0 degrees nose up at forward cg, and of course about 4 degrees at neutral cg.
Add 10 knots of wind from the nose, and all those numbers go up by about 3 to 4 degrees, due to main rotor downwash on the tail.
Floaternorthwest,
The position of the tail rotor has absolutely nothing to do with hover nose up attitude, whoever told you so should get a refund on their aero courses!
The S76 node attitude is due primarily to the 5 degrees of shaft tilt.
