I have to ask this:
What is the use of going with a traditional anti-torque rotor placement if you're rewriting the helicopter playbook?
What if, instead of an array of small rotors on the tail as he has now, he had two smaller sets of rotors either side of the aircraft?
He obviously isn't using a large airfoil at the back to induce force when at speed, and isn't using a linkage to the MR/gearbox.
So what benefits to the keeping TR in the traditional location instead of a more compact system, which would even have an added benefit of providing forward/backward thrust and thus reduce the demand on the battery by the MR?
