5. Operating Instructions
5.1 Firmware and Configuration
The flight controller comes pre-flashed with HGLRCF722 MINI firmware. For advanced configuration and tuning, connect the flight controller to your computer and use Betaflight Configurator software. Ensure you are using a compatible version of Betaflight.
5.2 Camera Switching
The SPECTER F722 Pro is equipped with two sets of camera signal outputs. You can switch between the front and rear cameras through the Betaflight setting mode. Refer to the Betaflight documentation for specific instructions on configuring camera switching.
5.3 Black Box Functionality
The flight controller includes a 16MB large-capacity black box. This feature ensures sufficient recording of flight data, which is invaluable for analyzing flight performance, tuning, and troubleshooting any issues. Data can be downloaded and analyzed using Betaflight Blackbox Explorer.
5.4 10V Electronic Switch
An integrated 10V electronic switch allows you to set its opening/off mode through Betaflight. This can be used to control various accessories that require a 10V power supply.

6. Maintenance
To ensure the longevity and optimal performance of your HGLRC SPECTER F722 Pro Flight Controller, follow these maintenance guidelines:
- Keep Clean: Regularly inspect the flight controller for dust, dirt, or debris. Use a soft brush or compressed air to gently clean the board.
- Inspect Connections: Periodically check all cable connections to ensure they are secure and free from damage. Loose connections can lead to intermittent issues or component failure.
- Avoid Physical Damage: Protect the flight controller from impacts and excessive vibrations. Consider using appropriate dampening mounts.
- Storage: When not in use, store the flight controller in a dry, anti-static environment, away from extreme temperatures.
- Firmware Updates: Keep the flight controller firmware updated to the latest stable version to benefit from performance improvements and bug fixes. Always back up your configuration before updating.
7. Troubleshooting
If you encounter issues with your HGLRC SPECTER F722 Pro Flight Controller, consider the following troubleshooting steps:
- No Power:
- Check all power connections from the battery to the ESC and then to the flight controller.
- Verify battery voltage is within the supported 2-6S LIPO range.
- Inspect for any visible damage to power traces or components.
- No Signal from Receiver:
- Ensure the receiver is correctly wired to the flight controller's designated receiver port.
- Check that the receiver is bound to your radio transmitter.
- Verify the correct serial protocol (e.g., SBUS, IBUS, CRSF) is selected in Betaflight.
- No Video Output:
- Confirm camera and VTX connections are correct according to the wiring diagram.
- Check VTX power and channel settings.
- Ensure the correct camera input is selected in Betaflight if using multiple cameras.
- Unstable Flight / Drifting:
- Calibrate the accelerometer and gyroscope in Betaflight.
- Check for excessive vibrations reaching the flight controller; consider soft mounting.
- Review PID settings in Betaflight; default settings may need minor adjustments for your specific drone build.
- Connection Issues with Betaflight Configurator:
- Ensure the correct USB drivers are installed for your flight controller.
- Try a different USB cable or port.
- Make sure no other software is using the COM port.
8. User Tips
While no specific user reviews or Q&A were provided, general tips for FPV flight controllers include:
- Start with Defaults: For initial setup, use the default Betaflight settings and only make small, incremental changes.
- Backup Configuration: Always save a backup of your Betaflight configuration (CLI dump) before making significant changes or firmware updates.
- Cable Management: Proper cable management is crucial to prevent wires from interfering with propellers or getting damaged during crashes.
- Heat Shrink/Conformal Coating: Consider applying heat shrink or conformal coating to exposed electronics for added protection against moisture and short circuits, especially in outdoor environments.
