Sikorsky X2 Powers up Propulsor

As you can clearly see, after a few months of testing with the aircraft powering just the coaxial rotors, they are not ramping up power to the tail propulsor.

The plan is to put drag-reducing fairings on the rotor, and then slowly transition to higher speeds, which would put more and more power toward the tail thruster, with the retreating blade stall being handled by offloading the blade as it moves aft.

They want to hit about 250kts by year's end.
