5. Setup

5.1 Mounting

1. Ensure the drone frame has appropriate mounting holes for a 57mm x 56mm stack.
2. Use vibration-damping standoffs if available, or secure the stack firmly to the frame using the provided hardware.
3. Orient the flight controller correctly according to your drone's flight direction. Refer to the flight controller's specific documentation for orientation settings in Betaflight/INAV.

5.2 Wiring

• Motor Connections: Connect the motor wires to the corresponding solder pads (M1, M2, M3, M4, etc.) on the ESC board. Ensure correct motor rotation direction will be set in software.
• Power Input: Solder the main battery lead (XT60/XT90 connector) to the large positive (+) and negative (-) pads on the ESC. Double-check polarity.
• Flight Controller to ESC: The stack is pre-connected. If separated, ensure the ribbon cable or pin headers connecting the FC to the ESC are securely seated.
• Receiver Connection: Connect your radio receiver (e.g., SBUS, CRSF, ELRS) to the appropriate UART port on the flight controller. Refer to the FC pinout diagram.
• Video Transmitter (VTX) & Camera: Connect the VTX and FPV camera to the designated pads/connectors on the flight controller, ensuring correct voltage and signal connections.
• GPS/Other Peripherals: Connect any additional peripherals (GPS, LED, Buzzer) to their respective UARTs or pads as per the flight controller's pinout.

5.3 Initial Configuration

1. Firmware: Connect the flight controller to your computer via a USB cable. Use Betaflight Configurator (or INAV Configurator, depending on FC firmware) to flash the latest stable firmware for your F722 or F405 board.
2. ESC Firmware: The ESC comes with Q_H_40_24_V0.19.2 firmware. If updating, use BLHeli_32 Configurator.
3. Basic Setup: Configure accelerometer calibration, receiver protocol, motor protocols (e.g., DShot600), and PID settings.
4. Motor Direction: Verify motor direction in the configurator's motor tab. Adjust as necessary.
5. Fail-safe: Configure fail-safe settings to ensure the drone lands safely in case of signal loss.

6. Operating Instructions

• Pre-Flight Check: Before each flight, inspect all connections, propeller integrity, and battery charge level.
• Arming: Arm the drone using the configured switch on your radio transmitter. Ensure propellers are clear before arming.
• Flight: Operate the drone responsibly. Start with gentle maneuvers to verify stability and control response.
• Disarming: Disarm the drone immediately after landing or in an emergency.
• Battery Management: Monitor battery voltage during flight and land before the voltage drops too low to prevent battery damage or unexpected power loss.

7. Maintenance

• Regularly inspect solder joints and wire connections for signs of wear or damage.
• Keep the flight controller clean and free from dust, dirt, and moisture. Use compressed air or a soft brush for cleaning.
• Check for firmware updates periodically to benefit from performance improvements and bug fixes.
• Store the drone and its components in a dry, cool environment when not in use.

8. Troubleshooting

8.1 No Power to Flight Controller

• Check main battery connection and polarity.
• Inspect for short circuits on the power distribution board or ESC.
• Verify USB cable connection if powering via USB.

8.2 Motors Not Spinning

• Ensure the drone is armed.
• Check motor wiring connections to the ESC.
• Verify motor protocol settings in the flight controller configurator.
• Calibrate ESCs if necessary (though DShot protocols typically do not require this).

8.3 Unstable Flight

• Check propeller balance and ensure they are undamaged.
• Verify flight controller mounting for excessive vibrations.
• Review PID tuning settings. Start with default settings if custom tuning is causing issues.
• Ensure correct flight controller orientation is set in the configurator.
