Which part of the drone is responsible for stabilizing flight?

The flight controller is the central component that stabilizes the drone during flight. It processes data from various sensors, including gyroscopes and accelerometers, to determine the drone's orientation and position. By constantly adjusting the speeds of the propellers, the flight controller maintains balance, ensures stable flight, and enables smooth maneuvers. This is crucial for safe operation, especially in windy conditions or when executing complex movements.

In contrast, propellers generate lift and allow the drone to move, but they do not inherently stabilize flight on their own. The battery serves as the power source, providing energy to all components but not affecting flight stability directly. The GPS module assists with navigation and positioning but does not stabilize flight; it can play a role in maintaining altitude through features such as GPS hold, but the primary stabilization function lies with the flight controller. This makes the flight controller the key element for maintaining flight stability in a drone.
