Function
Flight controller is soldered at top of ESC board. Its CPU runs Real-Time Operating System which acquires readings from all sensors and sends control signals to ESC units which control motors. Inertial Measurement Unit is the most important set of sensors, which informs the FC about the craft rotation and acceleration.
