5. Setup and Installation

Careful installation is crucial for the proper functioning of your flight controller. Follow these general guidelines:

1. Mounting: Secure the flight controller to your drone frame using the provided M3 screws. Ensure proper isolation from vibrations. The mounting hole pattern is 30.5mm x 30.5mm.
2. Wiring: Connect the flight controller to your Electronic Speed Controllers (ESCs), receiver, VTX (Video Transmitter), camera, and other peripherals using the included cables. Refer to the wiring diagram below for specific connections. The modular plug-in system simplifies this process.
3. Power Connection: Connect your LiPo battery (2-6S) to the main power input of your ESCs, which will then power the flight controller.
4. Firmware Flashing: Connect the flight controller to your computer via USB. Use the Betaflight Configurator software to flash the HGLRCF722 MINI firmware. Ensure you select the correct target.
5. Initial Configuration: After flashing, perform initial configuration in Betaflight Configurator. This includes setting up your receiver, ESC protocol, OSD, modes, and PID tuning.

6. Operating Instructions

Once the flight controller is installed and configured, follow these steps for operation:

1. Pre-Flight Checks: Before each flight, ensure all connections are secure, propellers are correctly installed, and battery is fully charged. Verify that your radio transmitter is powered on and bound to the receiver.
2. Arming the Drone: With the drone on a stable, level surface, arm the motors using the designated switch on your radio transmitter. Ensure no obstacles are near the propellers.
3. Flight Control: Use your radio transmitter to control the drone. The F722 Pro's MPU6000 gyroscope and STM32F722 processor provide stable and responsive flight characteristics.
4. OSD Monitoring: Monitor flight data such as battery voltage, current, flight time, and RSSI through the On-Screen Display (OSD) in your FPV goggles or monitor.
5. Disarming: After landing, disarm the motors using the designated switch on your radio transmitter.
6. Black Box Data: After flights, you can download and analyze the 16MB black box data using Betaflight Blackbox Explorer for performance review and tuning adjustments.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your flight controller:

• Visual Inspection: Periodically inspect the flight controller for any signs of physical damage, loose connections, or debris.
• Cleaning: Gently clean the board with a soft brush or compressed air to remove dust and dirt. Avoid using liquids directly on the board.
• Connection Integrity: Ensure all plug-in connections are firm and secure.
• Firmware Updates: Check the official HGLRC website or Betaflight resources for any available firmware updates. Update only if necessary and follow instructions carefully.
• Storage: When not in use, store the flight controller in a dry, anti-static environment.

8. Troubleshooting

If you encounter issues with your HGLRC SPECTER F722 Pro Flight Controller, consider the following troubleshooting steps:

• No Power:
  • Check battery connection and voltage.
  • Verify continuity of power cables.
  • Inspect for short circuits on the board.
• No Connection to Betaflight Configurator:
  • Ensure correct USB cable is used (data cable, not just charging).
  • Install necessary VCP (Virtual COM Port) drivers.
  • Try a different USB port or computer.
• Motors Not Arming:
  • Check Betaflight 'Modes' tab for correct arming switch setup.
  • Verify receiver input in Betaflight 'Receiver' tab.
  • Check for pre-arm conditions (e.g., accelerometer calibration, low battery warning, motor protocol errors).
• Unstable Flight:
  • Ensure flight controller is mounted securely and isolated from vibrations.
  • Perform accelerometer calibration in Betaflight.
  • Review PID tuning settings.
  • Check for bent or damaged propellers.
• OSD Not Displaying:
  • Verify OSD settings in Betaflight.
  • Check VTX and camera connections.

For more advanced troubleshooting, consult online FPV communities or the official HGLRC support channels.
