Wind-powered recharging for a weight-shifting coaxial helicopter

A helicopter comprising:

• a propulsion system comprising:
• a first rotor assembly comprising a first motor coupled to a first rotor, the first rotor comprising a plurality of first fixed-pitch blades;
• and
• a second rotor assembly comprising a second motor coupled to a second rotor, the second rotor comprising a plurality of second fixed-pitch blades, the second rotor being coaxial to the first rotor;
• a fuselage comprising:
• a power source;
• and
• a controller;
• and
• a gimbal assembly coupling the fuselage to the propulsion system, the gimbal assembly comprising a first gimbal motor and a second gimbal motor, the first and second gimbal motors being in stacked assembly and configured to weight-shift the helicopter;
• wherein the controller is communicably coupled to the first and second gimbal motors and is configured to provide instructions to at least one of the first or second gimbal motors in order to orient the plurality of first and second fixed-pitch blades into a position that permits wind to rotate the first and second fixed-pitch blades and thereby charge the power source.

A controller that is communicably coupled to a first gimbal motor and second gimbal motor of a helicopter, the controller configured to:

• provide instructions to at least one of the first gimbal motor or the second gimbal motor in order to orient a plurality of first fixed-pitch blades and second fixed-pitch blades into a position that permits wind to rotate the first and second fixed-pitch blades and thereby charge a power source;
• and
• wherein:
• the first gimbal motor is positioned along a first axis;
• the second gimbal motor is positioned along a second axis in stacked assembly with the first gimbal motor;
• and
• the second axis is perpendicular to the first axis.
