Just how the seeds manage to fall so slowly, however, has mystified scientists.
WebTail rotor. The tail rotor is a smaller rotor mounted vertically or near-vertically at the tail of a traditional single-rotor helicopter, where it rotates to generate a propeller -like horizontal thrust in the same direction as the main rotor 's rotation. The tail rotor's position and distance from the helicopter's center of mass allow it to ...
