The rotor blades and the electronics are now complete and have been added to the hub.

For now, the prototype will just be operated on battery power. Once the rotor has been tested, and shown to work, then the primary power source will be added.

Two 3.7V LiPo batteries provide the power (and will be the backup source for the final version). The batteries are tied together to provide the 7.4V needed to drive the servos. A voltage regulator is mounted on one half of the hub and provides power for the ESP32 dev board on the other side of the hub.

The hardware is now ready to test all of the capabilities, except for the primary power source. The next step is to develop the Firmware so that more complex testing can begin
