6. Operating Instructions

6.1 Firmware Configuration

The Borg F7 Mini Flight Controller supports Betaflight and INAV firmware. The recommended firmware targets are:

• Betaflight Firmware Target: IFLIGHT_BLITZ_F722
• INAV Firmware Target: IFLIGHT_BLITZ_F722

The Borg 60 Mini ESC uses BL32 (32bit ESC) firmware. The recommended target is:

• ESC Firmware Target: IFLIGHT_BLITZ_G3 32.9

Connect your flight controller to a computer via USB and use the respective configurator software (Betaflight Configurator or INAV Configurator) to flash the firmware and configure settings according to your drone build and preferences.

6.2 VTX ON/OFF Mode Command

To enable VTX ON/OFF functionality, use the following commands in the Betaflight CLI (Command Line Interface):

resource PINIO 1 PC0
set pinio_config = 1,1,1,1
set pinio_box = 40,41,255,255
set box_user_1_name = VTX_ON_OFF
aux 0 40 8 900 2100 0 0
save
            

After entering these commands, save the configuration. This will allow you to control the VTX power via a switch on your remote controller, configured in the Modes tab of Betaflight Configurator.

7. User Tips

• Always double-check motor rotation direction in the configurator before flying.
• Ensure proper heat dissipation for the ESC, especially during aggressive flying.
• Regularly inspect all solder joints and connections for wear or damage.
• Keep your firmware updated to the latest stable versions for optimal performance and bug fixes.

8. Maintenance

• Cleaning: Gently clean the boards with a soft brush or compressed air to remove dust and debris. Avoid using liquids.
• Inspection: Periodically inspect for any signs of physical damage, loose connections, or burnt components.
• Storage: Store the components in a dry, cool environment, away from direct sunlight and static electricity.

9. Troubleshooting

• No Power: Check battery connection, polarity, and ensure no short circuits. Verify power cables are securely soldered.
• Motors Not Spinning: Ensure ESCs are armed, motor wires are correctly connected, and motor protocols are configured in the FC firmware. Check for continuity in motor windings.
• Intermittent Signal: Check receiver connections, antenna placement, and ensure no interference from other electronic components.
• Unstable Flight: Verify PID settings, motor balance, and propeller condition. Ensure the flight controller is mounted securely and isolated from vibrations.
• VTX Issues: Check VTX power supply, antenna connection, and ensure VTX protocol is correctly configured in the FC.
