ABSTRACT:
A helicopter moving device has a lever arm, a helicopter support arm to attach to a helicopter, and a wheel mounted to the lever arm, such that applying downward pressure to the lever arm causes a corresponding upward movement of the helicopter support arm about a pivot point. In this manner, the helicopter may be moved from place to place along the ground. The helicopter moving device is lightweight, capable of being disassembled, self propelled (does not require external power source) and portable.
