5. Setup and Installation
Careful installation is crucial for optimal performance and safety. Always ensure your drone is disconnected from power during installation.
5.1 Physical Installation
- Mounting the Stack: Use the provided M3 screws, nylon nuts, and silicone anti-shake pads to mount the FC and ESC boards onto your drone frame. The silicone pads are essential for isolating the gyroscope from frame vibrations.
- Orientation: Ensure the flight controller is oriented correctly according to your drone's frame and BetaFlight settings.


5.2 Wiring Connections
- Battery Connection: Solder the XT60 power cable to the designated battery pads on the ESC. Ensure correct polarity. The ESC supports 3-8S LiPo input.
- Motor Connections: Solder your drone's motor wires to the corresponding motor pads (M1-M4) on the ESC.
- FC to ESC Connection: Use the provided flight controller adapter cable to connect the FC to the ESC. This typically handles motor signals, telemetry, and power.
- DJI Air Unit: Use the dedicated DJI Air Unit adapter cable for direct plug-and-play connection to your DJI Air Unit.
- Camera: Connect your FPV camera using the provided camera connection cable to the appropriate pads on the FC.
- Receiver: Connect your radio receiver to one of the available UARTs on the FC. Refer to the FC's pinout diagram for specific UART assignments.
- GPS/Other Peripherals: If using additional peripherals like GPS, connect them to available UARTs or I2C pads as required.


5.3 Software Configuration
- Connect to PC: Connect the FC to your computer using a Type-C USB cable.
- BetaFlight Configurator: Open the BetaFlight Configurator software.
- Firmware Flashing: Ensure the correct firmware target (GEPRCF722) is flashed to the FC. For the ESC, the firmware target is B_X_30.
- Initial Setup: Follow the BetaFlight setup wizard to configure your receiver, motors, OSD, and other drone parameters.
- Gyroscope Calibration: Calibrate the accelerometer and gyroscope on a level surface.
- Motor Direction: Verify motor directions in BetaFlight and adjust if necessary.
- Black Box: Configure black box logging settings to utilize the 16M onboard storage for flight analysis.
6. Operating Instructions
Once installed and configured, the GEPRC TAKER F722 BLS 65A V2 STACK is ready for flight.
- Pre-Flight Checks: Always perform thorough pre-flight checks, including battery voltage, propeller security, and control surface response.
- Arming: Arm your drone using the configured switch on your radio transmitter.
- Flight Modes: Utilize various flight modes configured in BetaFlight (e.g., Acro, Angle, Horizon) according to your skill level and flight environment.
- OSD Monitoring: Monitor critical flight data (voltage, current, flight time, RSSI) via the BetaFlight OSD displayed in your FPV goggles.
- Data Analysis: After flights, connect the FC to your PC to download and analyze black box logs for tuning and troubleshooting.
7. Maintenance
- Regular Inspection: Periodically inspect all solder joints, cables, and connectors for signs of wear, corrosion, or damage.
- Cleaning: Keep the boards clean from dust, dirt, and debris. Use compressed air or a soft brush. Avoid using liquids directly on the electronics.
- Firmware Updates: Regularly check for and apply firmware updates for both the FC (BetaFlight) and ESC (BLHeli_S/BLHeli_32) to benefit from performance improvements and bug fixes.
- Component Replacement: If any component is damaged, replace it with an identical or compatible part.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not arm | Throttle too high, arming switch not set, receiver not connected/configured, safety features (e.g., low battery) active. | Ensure throttle is at its lowest point. Check arming switch assignment in BetaFlight. Verify receiver connection and configuration (UART, protocol). Check battery voltage. |
| Motors not spinning or spinning incorrectly | Incorrect motor wiring, ESC calibration issue, wrong motor direction, damaged motor/ESC. | Check motor wiring to ESC. Calibrate ESCs. Reverse motor direction in BLHeliSuite/BetaFlight if needed. Inspect motors and ESC for physical damage. |
| No video feed from FPV camera | Camera not powered, video signal cable disconnected, VTX issue, OSD misconfiguration. | Verify camera power and video signal connections. Check VTX functionality. Ensure OSD is enabled and configured correctly in BetaFlight. |
| Unstable flight / excessive vibrations | Loose propellers, unbalanced motors, soft mounting issues, incorrect PID tuning. | Check propeller tightness and balance. Ensure motors are securely mounted. Verify silicone anti-shake pads are correctly installed. Adjust PID tuning in BetaFlight. Analyze black box logs for vibration sources. |
| FC not connecting to BetaFlight Configurator | Driver issues, faulty USB cable, incorrect COM port selected, FC in DFU mode. | Install correct DFU/VCP drivers. Try a different USB cable. Select the correct COM port. If in DFU mode, flash firmware. |
9. User Tips
- Solder Quality: Always ensure clean and strong solder joints. Cold solder joints are a common cause of intermittent issues and can lead to component failure.
- Cable Management: Route cables neatly and secure them to prevent interference with propellers or other moving parts. Good cable management also aids in troubleshooting and maintenance.
- Heat Shrink: Use heat shrink tubing on exposed solder joints and connections to prevent short circuits and provide mechanical protection.
- Testing: Before maiden flight, perform a "smoke stopper" test to prevent damage in case of a short circuit. Always test motor spin direction and responsiveness with propellers removed.
- Backup Settings: Always save a backup of your BetaFlight configuration (CLI dump) after successful setup and tuning. This allows for quick restoration if settings are lost or corrupted.
