Setup and Installation
Proper installation is crucial for the performance and longevity of your GEPRC Taker F722 BT Stack. Follow these general guidelines:
- Mounting the Stack:
Use the provided silicone anti-shake pads and nylon nuts to mount the Flight Controller (FC) and Electronic Speed Controller (ESC) boards. The mounting holes are 30.5x30.5mm. The silicone rings reduce vibrations, ensuring stable gyroscope performance. Ensure the FC is oriented correctly as per your flight control software (e.g., BetaFlight) settings.

Connect the XT60 (or XT90, depending on your specific ESC variant) power cable to your LiPo battery. Ensure correct polarity. The stack supports 3-6S LiPo input voltage (3-8S for 65A ESC variant).
- Motor Connections:
Connect your drone's motors to the ESC board. The ESC supports Dshot 150/300/600 protocols. Refer to the ESC board layout for M1, M2, M3, M4 motor pads. Proper soldering is essential for reliable motor operation.

Utilize the provided connection cables for various peripherals:
- DJI Air Unit: The FC directly plugs into the DJI Air Unit using the dedicated adapter cable for video and control integration.
- Camera: Connect your FPV camera using the camera connection cable to the designated camera input.
- VTX (Video Transmitter): Connect your VTX using the VTX connection cable for video signal transmission.
- Receiver: Connect your radio receiver to the appropriate UART on the FC. The FC has 5 UART groups (UART4 is fixed for Bluetooth).
- O3 3-in-1 Connection Cable: Use this for integrated connections if applicable to simplify wiring.
- Initial Configuration:
Connect the FC to your computer via the Type-C USB interface. Use BetaFlight Configurator (or similar flight control software) to load the appropriate firmware (target: GEPRCF722_BT_HD_V3) and configure settings such as motor direction, PID tuning, and OSD elements. The ESCs come pre-installed with BL32 test firmware (for 50A variant) or are compatible with B_X_30 target firmware (for 60A/65A variants). Always back up your configuration before making major changes or flashing new firmware.
Operating Instructions
- Powering On:
Ensure all connections are secure and propellers are removed for safety before connecting the LiPo battery. The FC will power on and initialize. Listen for the ESC startup tones, indicating successful initialization.
- Pre-Flight Checks:
Before each flight, perform a visual inspection of all components and connections. Verify that the propellers are correctly installed and tightened. Check flight control software for any error messages or warnings, and confirm battery voltage and signal strength.
- Bluetooth Parameter Tuning:
The FC supports Bluetooth for wireless parameter tuning. Use a compatible mobile application (e.g., SpeedyBee App) to connect to the FC and adjust settings without needing a USB cable. This feature is highly convenient for field adjustments and quick tweaks.
- Flight Data Recording (Black Box):
The 512M onboard black box automatically records detailed flight data. This data can be downloaded via the USB interface after your flight and analyzed using tools like Blackbox Explorer to diagnose flight performance issues, optimize PID tunes, or review flight characteristics.
- OSD (On-Screen Display):
The integrated BetaFlight OSD will display critical flight information (e.g., battery voltage, flight mode, RSSI, current draw) directly on your FPV video feed. Configure the OSD layout and displayed elements within BetaFlight Configurator to suit your preferences.
Maintenance
Regular maintenance helps ensure the reliability and performance of your GEPRC Taker F722 BT Stack:
- Cleaning: Periodically clean the boards to remove dust, dirt, or debris. Use a soft brush or compressed air. Avoid using liquids directly on the electronics.
- Inspection: Regularly inspect all solder joints and connections for signs of damage, corrosion, or loose wires. Check for any physical damage to the boards or components, especially after crashes.
- Firmware Updates: Keep your FC and ESC firmware updated to the latest stable versions. This can improve performance, add new features, and fix bugs. Always back up your configuration before updating firmware.
- Shock Absorbers: Inspect the silicone anti-shake pads for wear or damage. Replace them if they appear degraded to maintain optimal gyroscope performance and reduce vibrations transmitted to the FC.
Troubleshooting
If you encounter issues with your GEPRC Taker F722 BT Stack, consider the following troubleshooting steps:
- No Power/No Lights:
- Check battery connection and voltage.
- Inspect power cable (XT60/XT90) for damage or incorrect polarity.
- Verify solder joints for the main power input on the ESC.
- Motors Not Spinning/Incorrectly:
- Ensure motor connections to the ESC are secure and correct.
- Check motor direction in BetaFlight Configurator and adjust if necessary.
- Verify ESC calibration (if applicable) and firmware.
- Confirm Dshot protocol settings match your ESC in BetaFlight.
- No FPV Feed/OSD Issues:
- Check camera and VTX connections for continuity and correct wiring.
- Verify VTX power and channel settings match your FPV goggles/monitor.
- Ensure OSD is enabled and configured correctly in BetaFlight.
- Unstable Flight/Oscillations:
- Check for loose mounting or damaged silicone pads, which can cause vibration.
- Review PID tuning settings in BetaFlight; default PIDs may need adjustment for your specific frame and motors.
- Inspect propellers for damage or imbalance.
- Analyze black box logs for insights into flight behavior and potential issues.
- Bluetooth Connection Issues:
- Ensure Bluetooth is enabled on your mobile device and the app has necessary permissions.
- Verify the FC's Bluetooth module is active (UART4 is typically dedicated).
- Try restarting both the FC (by unplugging/replugging battery) and your mobile device.
- USB Connection Problems:
- Try a different Type-C USB cable, as some cables are charge-only.
- Ensure BetaFlight Configurator is up-to-date.
- Check device manager for proper driver installation (e.g., STM32 Virtual COM Port Driver).
User Tips
- Always perform a "dry run" (without propellers) after any significant changes to wiring or configuration to ensure motors spin correctly and safely.
- When updating firmware, always save a full backup of your current configuration (using `diff all` or `dump` commands in the CLI) in BetaFlight Configurator. This allows you to restore settings easily.
- Utilize the Bluetooth tuning feature for quick adjustments at the field, but for major configuration changes or initial setup, a wired USB connection is often more reliable and provides full access.
- Pay close attention to the mounting of the FC; proper vibration isolation is key for optimal flight performance, especially for the gyroscope. Ensure screws are snug but not overtightened.
