How It All Works Together
-
The Battery provides power to the system.
-
The Flight Controller receives commands from the remote control.
-
It instructs ESCs to spin the motors at specific speeds.
-
Propellers push air down, creating lift and thrust.
-
Sensors (like gyroscope and accelerometer) report balance data back to the flight controller.
-
The GPS and receiver keep the drone stable and responsive to the pilot’s controls.
It’s like a team of specialists — each part plays a unique role to make flight possible.
