ArduCopter uses attitude and position controllers as core flight modes. Position control builds on attitude control for three-dimensional movement. Attitude controller converts desired angles to roll and pitch rates. Rate controller uses PID to compute motor commands from angular rates
ESC acts as brain of electric propulsion system, controlling motor speed based on throttle signals. Uses direct current from battery to deliver alternating three-phase current to motor. Throttle controller varies motor speed by modifying switch opening/closing rate
