3.1 Component Connections
- Magt: Connect the main power source to the designated POWER port.
- ESC (Electronic Speed Controller): Connect ESCs to the PWM output pins (1-10) for motor control.
- Receiver (RC IN): Connect your receiver (PPM/SBUS compatible) to the RC IN port.
- GPS/I2C: Connect a GPS module (e.g., TS100 GPS) to the GPS/I2C port for navigation and position hold functions.
- OSD: The OSD module is integrated. No external connection is needed for basic OSD functionality.
- TELEMETRY (TELE1, TELE2): Connect telemetry modules for real-time data transmission.
- USB: Use the USB port for connecting to a computer for configuration and firmware updates.
- Summer: Connect an external buzzer to the BUZZER port for audible alerts.
- Valgfrit periferiudstyr: Connect other sensors such as obstacle avoidance, optical flow, or FPV cameras as per the connection guide.
3.2 Softwarekonfiguration
The CrossFlight V1.1 can be configured using several mission planner software options:
- Radiolink Mission Planner (Recommended for firmware updates)
- ArduPilot Mission Planner
- QGC Mission Planner (QGroundControl)
Connect the flight controller to your computer via the USB port and launch your preferred mission planner software to calibrate sensors, configure flight modes, and set parameters.

5. Vedligeholdelse
5.1 Generel pleje
- Keep the flight controller clean and free from dust and moisture.
- Undgå at udsætte enheden for ekstreme temperaturer eller direkte sollys i længere perioder.
- Regularly inspect all connections for secure fit and signs of wear.
- Ensure proper ventilation when the unit is in operation to prevent overheating.
5.2 firmwareopdateringer
Firmware updates for the CrossFlight V1.1 can only be performed using the Radiolink Mission Planner software and firmware provided directly by Radiolink. Attempting to use other mission planners or unofficial firmware may lead to unexpected behavior or render the device inoperable.
6. Fejlfinding
- Forbindelsesproblemer: If the flight controller is not recognized by the mission planner, ensure the USB cable is securely connected and try a different USB port. Verify that the correct drivers are installed.
- Firmwareopdateringsfejl: Ensure you are using the official Radiolink Mission Planner and the correct firmware file from Radiolink. Do not interrupt the update process. If an update fails, attempt to re-flash the firmware carefully.
- Unstable Flight/Altitude Hold: Check all sensor calibrations (accelerometer, gyroscope, compass, barometer). Ensure the flight controller is securely mounted and isolated from vibrations. Verify that the air pressure vent is clear.
- OSD Not Displaying Data: Confirm that the OSD settings are correctly configured in the mission planner. Check video connections if using an external display.
- ArduPilot Compatibility: Note that while the CrossFlight V1.1 can be configured with ArduPilot Mission Planner, the ArduPilot Development Team has expressed concerns regarding source code compliance. For firmware updates, only use Radiolink's dedicated tools and firmware.
