Electronic Speed Controller (ESC) Board
The ESC contains the MOSFETs and microprocessors required to drive the brushless motors. A status error indicates the onboard logic has failed its power-on self-test (POST) or the communication bus is unresponsive due to a hardware short. Replacing the board restores the switching logic and communication link to the flight controller.

Brushless Propulsion Motor
If a motor winding is partially shorted or has high internal resistance, the ESC will detect an abnormal current draw during the initial startup phase. To prevent a catastrophic thermal event, the ESC will trigger a propulsion error and refuse to arm. Replacing the motor ensures the ESC sees a nominal load.

ESC Signal Ribbon Cable
The flight controller communicates with the ESC via a high-density signal cable. Vibration or impact can cause micro-fractures in these traces or loosen the ZIF connectors, leading to a 'Status Error' because the flight controller cannot receive telemetry from the ESC microcontroller.
