3.3. Firmware Flashing

The F405-WING-V2 supports two main firmware options:

ArduPilot: Use MatekF405-Wing target (ArduPlane 4.4 or newer).
INAV: Use MATEKF405SE target (INAV 6.0 or newer).

Connect the flight controller to your computer via the USB Type-C port. Use the respective configurator software (Mission Planner for ArduPilot, INAV Configurator for INAV) to flash the desired firmware and perform initial configuration. Follow the detailed instructions provided by the ArduPilot or INAV communities for specific setup procedures.

4. Operation

4.1. Pre-Flight Checks

Before each flight, ensure all connections are secure, propellers are correctly installed, and the battery is fully charged. Verify that the flight controller is properly calibrated and all control surfaces respond correctly to transmitter inputs.

4.2. Flight Modes

Configure flight modes in your chosen firmware (ArduPilot or INAV) according to your preferences and aircraft type. Common modes include Manual, Stabilize, RTH (Return to Home), and Auto. Understand the function of each mode before flight.

4.3. Data Logging

The integrated MicroSD card slot allows for blackbox logging of flight data. This data is crucial for analyzing flight performance, tuning PID values, and troubleshooting any issues. Ensure a MicroSD card is inserted before flight to record data.

5. Maintenance

5.1. Regular Inspection

Periodically inspect the flight controller and its connections for any signs of wear, damage, or loose wires. Check for dust or debris accumulation, especially around the barometer and IMU.

5.2. Firmware Updates

Keep your flight controller firmware updated to the latest stable version. Firmware updates often include bug fixes, performance improvements, and new features. Always back up your configuration before performing a firmware update.

5.3. Cleaning

Gently clean the board with a soft brush or compressed air to remove dust. Avoid using liquids or harsh chemicals. Ensure the USB port is free of debris.

6. Troubleshooting

No Power: Check battery connection, input voltage range (9-30V), and ensure no short circuits. Verify BEC outputs with a multimeter.
No Sensor Data (IMU/Baro): Ensure the flight controller is powered correctly. Re-flash firmware if necessary. Check for physical damage to the sensors.
Receiver Not Responding: Verify receiver wiring to the SBUS port. Ensure the receiver is bound to the transmitter and powered correctly. Check SBUS inverter settings in firmware.
OSD Not Displaying: Check OSD wiring to VTX/Camera. Ensure OSD is enabled and configured in the firmware.
Flight Instability: Review PID tuning parameters. Check for vibrations affecting the IMU. Ensure correct motor/servo direction and calibration.
Blackbox Not Logging: Ensure a formatted MicroSD card is inserted. Verify blackbox logging is enabled in the firmware settings.

For more detailed troubleshooting, consult the official ArduPilot or INAV documentation and community forums.
