You can engineer some of it out - contra rotating twin rotors is one way. The Wessex and Sea King had something called starboard lateral lead where the output from the mixing unit was proportionally longer to the starboard lateral jack than the port one - as you raise the lever, it tilts the disc slightly to the left for you helping counteract the TR drift.
Various gearbox tilts are another option but ISTR they were mostly forward to reduce mastbending stress in the cruise.
Which conventional helos don't hover one skid low Syd? And the answer isn't 'ALL of them if you leave the ground power connected'
