Claim 0:
1. A flying machine, comprising:
a body;
at least one robotic arm extending from the body, said at least one robotic arm comprising an end effector, said at least one robotic arm terminating in the end effector;
one or more main rotor assemblies:
a variable length tail positioned on the opposite side of the body with respect to said it least one robotic arm, and a plurality of linked battery cells spaced parallel to each other throughout the variable length tail, wherein the variable length tail is configurable with varying length by rolling-in and rolling out;
a motor to regulate the length of the variable length tail by rolling-in and rolling out the variable length tail; and
a controller linked to the motor, wherein the controller is configured to maintain the center of mass of the flying machine in response to changes in payload carried by the end effector by causing the motor to roll-in and roll out the variable length tail.
