Plugged in battery and tested. Found a few bugs. Bug one: one of the motors didn’t work. I resoldered all connections and replaced the motor with a working one, but the motor still didn’t spin. So then I uncapped the battery pull from the motor to see if it was a power issue. The motor still didn’t spin. Then I resoldered all connections, but the motor still didn’t spin. Then I came to the conclusion that it was an issue with the connecting bullet plug wires, so I ordered them. I also wrote some of the code for the Python autonomous flight by SSHing into the Raspberry Pi.
