4. Installation and Setup

4.1 Mounting

The GEP-TAKER G4 35A AIO is designed for flexible mounting with hole patterns of 25.5-26.5mm and a diameter of Φ3.05mm. Ensure the flight controller is securely mounted to your drone frame using appropriate standoffs and screws to prevent vibration interference.

4.2 Wiring

The power supply and motor wire pads have been optimized for easier welding. Carefully connect your motors, receiver, VTX, camera, and other peripherals to the designated UART ports (R1 T1 / R2 T2 / R4 T4 / R5 T5) and other connection points on the board. For detailed wiring diagrams and connection instructions, please refer to the official user manual PDF available at: GEPRC GEP-TAKER G4 35A AIO User Manual (PDF).

4.3 Software Configuration

The flight controller runs on Betaflight firmware with a target of TAKERG4AIO. Connect the board to your computer via the Type-C USB port and use the Betaflight Configurator software to flash the correct firmware, configure OSD settings (AT7456Ev), calibrate sensors, set up motor outputs (supporting Dshot600, Oneshot, Multishot), and configure your receiver and flight modes. Ensure you are using the latest stable version of Betaflight Configurator for optimal performance and compatibility.

5. Operating Instructions

The GEP-TAKER G4 35A AIO operates with a 2~4S LIPO battery input voltage. Once properly installed and configured in Betaflight, the flight controller manages your drone's flight characteristics. The integrated OSD (On-Screen Display) provides real-time flight data directly to your FPV goggles or monitor. The board includes support for a buzzer and LED indicators, which can be configured in Betaflight for various alerts and status indications.

• Power On: Connect a 2-4S LIPO battery to the drone. The flight controller will initialize.
• Arming: Arm the drone using your configured switch on the remote controller. Ensure propellers are clear before arming.
• OSD: Monitor flight data such as battery voltage, flight time, and RSSI through the Betaflight OSD.
• Buzzer/LED: Utilize the buzzer for low battery warnings or lost model alarms, and LEDs for status indication, as configured in Betaflight.

6. Maintenance

To ensure the longevity and reliable performance of your GEP-TAKER G4 35A AIO flight controller, follow these maintenance guidelines:

• Regular Inspection: Periodically check all solder joints and connections for looseness or damage.
• Cleanliness: Keep the board free from dust, dirt, and moisture. Use compressed air or a soft brush for cleaning.
• Physical Damage: Inspect for any cracks, bent pins, or other physical damage, especially after a crash.
• Firmware Updates: Keep your Betaflight firmware updated to the latest stable version to benefit from bug fixes and new features.

7. Troubleshooting

If you encounter issues with your flight controller, consider the following troubleshooting steps:

• No Power: Check battery connections, power leads, and ensure the BEC output is functioning (5V@3A).
• No Signal to Motors: Verify ESC connections, motor protocols (Dshot600, Oneshot, Multishot) in Betaflight, and motor calibration.
• Connection Issues (USB): Ensure you have the correct drivers installed for the STM32 MCU. Try a different Type-C USB cable or port.
• Unstable Flight: Re-check mounting for vibrations, recalibrate accelerometers and gyroscopes in Betaflight, and review PID settings.
• OSD Not Displaying: Confirm OSD settings in Betaflight Configurator and check camera/VTX connections.

8. User Tips

• Solder Quality: Good soldering is crucial for reliable performance. Use a quality soldering iron and appropriate solder.
• Component Protection: Consider applying conformal coating to protect the board from moisture and environmental elements, especially for outdoor FPV flying.
• Backup Settings: Always save a backup of your Betaflight configuration before making significant changes or firmware updates.
• Start Simple: If you are new to FPV, start with basic configurations and gradually introduce more advanced features.

9. Compliance and Safety Information

⚠️ Disclaimer: For recreation use only. Illegal modification of drones/planes is prohibited. Please also pay attention to the relevant laws and regulations on the use of drones/planes in your country/area to ensure legal use.
