Eurocopter X3 reaches speed of 255 knots
Twin 2000 HP turbines drive the main rotor as well as the two propellers. There must be some fancy mechanicals in there because the props are driven at different speeds (the right hand prop runs faster because it also acts as the anti-torque reactor), and the main rotor speed is independent of the prop speed.
