Maybe, the jet-tip concepts can be a solution for not having a tail rotor cause the main blades are not producing torque to make the helicopter turn separately to the rotors' rotation. In this case, the rear wings of this helicopter concept turn the helicopter in directions like an airplane, but when it comes to rotating itself while hovering, its little wings attached to main fuselage of the helicopter will help.

I hope you like it^^
