frame, Provides the main structure of the quadcopter. It typically has four arms for the motors and a body that holds the other components., motor, Produces rotation and works together with the propeller as part of the drone’s powertrain., propeller, Is attached to the motor and produces thrust when it rotates. Its size is normally specified by its diameter, while its pitch refers to the blade angle., ESC (Electronic Speed Controller), Controls the power sent to each motor so that the motors can spin at precise rates needed to maintain stability., flight controller (FC), Acts as the main control hub or “brain” of the quadcopter. It controls the ESCs and is connected to the FPV system and receiver., flight stack, Refers to the ESC and flight-controller boards mounted together, one on top of the other., battery, Supplies electrical power to the drone. Its number of cells is directly linked to its voltage., connector, Connects the battery to the drone. The battery and drone need matching types of this component., receiver (Rx), Receives the control signal from the transmitter and is connected to the flight controller as part of the radio link., FPV system, Provides the pilot with a first-person view of where the drone is flying., goggles, Display the video feed from the drone so that the pilot can see where the drone is flying., transmitter / radio / controller, Sends commands to the drone and is also referred to as a radio, remote or controller., beeper /buzzer, Produces a loud sound and can also flash an LED, helping the pilot locate a drone that has gone down., Betaflight firmware, Is the software that runs on the flight controller., Betaflight configurator, Is an app used to adjust the drone’s settings., power distribution board (PDB), A circuit board that distributes electrical power from the battery to the drone’s electronic components
