2. Wiring Connections

Connect the flight controller to the 4in1 ESC using the provided ribbon cable or individual wires, ensuring correct pin alignment for power, ground, and signal lines (e.g., DShot).

• Power Input: Connect your LiPo battery (3-8S for FC, 3-6S for ESC) to the main power pads on the ESC. Ensure correct polarity.
• Motors: Connect motor wires to the corresponding pads on the 4in1 ESC.
• Receiver: Connect your receiver (ELRS, TBS, SBUS, IBUS, DSM2, DSMX) to the appropriate UART on the flight controller. Refer to the FC pinout for specific UART assignments.
• FPV Camera/VTX: Utilize the 5V or 10V BEC outputs for powering your FPV camera and video transmitter.
• Peripherals: Connect other peripherals like GPS, LED strips, or buzzers to their designated pads.

3. Firmware Flashing and Configuration

• Connect the flight controller to your computer via the USB Type-C port.
• Open Betaflight Configurator (or similar flight control software).
• Flash the recommended firmware (Betaflight 4.3.1 JHEF7DUAL.HEX) if necessary.
• Configure your receiver, motors, ESC protocols (DShot600 recommended), OSD, and other settings according to your drone build and preferences.
• Calibrate the accelerometer and gyroscope.

Operating Instructions

Pre-Flight Checks:

1. Ensure all connections are secure and free from shorts.
2. Verify propeller direction and motor spin direction in Betaflight.
3. Check battery voltage and ensure it is within the safe operating range.
4. Confirm radio control functionality and arming switch.

First Flight:

• Perform the first flight in an open, safe area away from people and obstacles.
• Start with gentle throttle inputs and observe drone behavior.
• Land immediately if any unusual behavior is observed.

Maintenance

• Regular Inspection: Periodically check for loose connections, damaged wires, or signs of overheating on the FC and ESC.
• Cleaning: Keep the boards free from dust, dirt, and moisture. Use compressed air or a soft brush for cleaning.
• Firmware Updates: Check for new firmware releases for Betaflight and BLHeli-S to benefit from performance improvements and bug fixes.
• Heat Management: Ensure adequate airflow around the stack, especially the ESC, to prevent overheating during aggressive flight.

Troubleshooting

Drone not arming:

Check Betaflight configurator for arming flags (e.g., NO_GYRO, RX_LOSS, FAILSAFE). Ensure your radio is connected and calibrated, and the arming switch is correctly assigned.

Motors not spinning correctly:

Verify motor direction in Betaflight. Check ESC protocol settings (DShot, Multishot). Ensure motor wires are securely connected and not shorted.

No OSD display:

Confirm OSD is enabled in Betaflight. Check video signal connections between camera, FC, and VTX. Ensure correct NTSC/PAL setting.

Intermittent power issues:

Inspect all power connections, especially the main battery lead and capacitor. Check for cold solder joints or damaged wires. Ensure battery voltage is sufficient.

Safety Information

• Always remove propellers before connecting the battery for configuration or testing.
• Never operate your drone near people, animals, or property.
• Be aware of local regulations regarding drone operation.
• Use appropriate safety gear, such as safety glasses, when working with soldering irons or power tools.
• Ensure proper ventilation when soldering.
