4. Setup
4.1 Connecting to Mission Planner
To configure your Mini PIX Flight Controller, you will need to connect it to a computer running Mission Planner software. Mission Planner can be downloaded from the Radiolink official website.
- Connect the Mini PIX to your computer using the provided USB cable.
- Ensure the yellow LED on the Mini PIX flashes, indicating it's recognized.
- In Mission Planner, select the correct COM port (e.g., COM5 for Crossflight) and set the baud rate to 115200 for USB connection.
- Click 'Connect' to establish communication.
4.2 Accelerometer Calibration
Accurate accelerometer calibration is crucial for stable flight. This process is performed within Mission Planner.
- After connecting to Mission Planner, navigate to the 'Setup' section, then 'Mandatory Hardware', and select 'Accel Calibration'.
- Follow the on-screen prompts to place the flight controller in various orientations (level, left, right, nose down, nose up, back).
- For each orientation, ensure the flight controller is stable and click the corresponding 'Click when done' button.
- Once all orientations are calibrated, the software will indicate 'Calibration successful'.
- Verify the calibration by observing the attitude indicator in Mission Planner; it should accurately reflect the physical orientation of the flight controller.

4.3 Firmware Installation
The firmware for the Mini PIX Flight Controller can be installed or updated using Mission Planner. Note that only Radiolink firmware is supported for installation via Radiolink Mission Planner.
- Connect the Mini PIX to your computer via the USB cable. Do not install firmware by wireless data transmission.
- In Mission Planner, navigate to 'Setup' and then 'Install Firmware'.
- Ensure the flight controller is recognized (status will show 'Found board type'). If not, unplug and re-plug the USB cable.
- Select the desired firmware type (e.g., 'Copter' for multirotors, 'Plane' for fixed-wing, 'Heli' for helicopters) by clicking the corresponding icon.
- Confirm the firmware upload when prompted. The progress bar will show the installation status.
- Once the upload is complete, the firmware is successfully installed.

5. Operating Modes
The Mini PIX Flight Controller supports several flight modes to accommodate different skill levels and operational requirements:
- PosHold Mode: Maintains the vehicle's position and altitude automatically. Ideal for beginners or when precise hovering is required.
- Stabilize Mode: Automatically levels the aircraft when control sticks are released, providing a stable platform while allowing manual control over movement.
- Acro Mode: Provides direct control over the aircraft's angular rates, allowing for advanced maneuvers and acrobatic flight. This mode requires more pilot skill.
These modes can be switched at any time during flight, offering flexibility for both novice and experienced pilots.
