What you see above is supposedly the world’s fastest helicopter. Called the Eurocopter X3, this helicopter can travel at upto 430 kph. That’s almost twice the speed of the regular ones. “The X3’s speed milestone was reached on May 12 during stable, level flight – with the hybrid demonstrator maintaining a true airspeed of 232 kts. (430 km./hr.) for several minutes. This occurred during only the third mission after a scheduled upgrade that integrated the X3’s definitive gearboxes, enabling it to operate at full power.”
