The Flight Controller (FC) is the central intelligence of a drone, responsible for control, stability, and real-time flight data processing. Acting as the drone’s nervous system, it collects and analyzes data from various sensors, including gyroscopes, accelerometers, and barometers, making instant adjustments to ensure smooth and stable flight.
 

As a critical component, the FC ensures precise altitude control, stability, and responsiveness to pilot commands, making it essential for both professional and recreational drone applications.
