4. Setup and Assembly
The CADDXFPV gimbal is designed for quick and straightforward assembly. Follow these general steps for installation:
- Mounting the Gimbal: Securely attach the gimbal to your FPV platform (UAV, fixed-wing, or RC car) using appropriate mounting hardware (not included, or specific to your platform). Ensure it is firmly fixed to prevent vibrations.
- Camera Installation: Insert your compatible 19mm FPV camera into the gimbal's camera slot. Ensure it is seated correctly and secured.
- VTX Connection: Connect the gimbal to a compatible VTX (Video Transmitter) using the provided coaxial cable. This connection is crucial for enabling head tracking functionality. Refer to your VTX and flight controller manuals for specific wiring diagrams if needed.
- Power Connection: Connect the gimbal to a power source within the specified voltage range (7-26V).
- Initial Calibration (if applicable): After power-up, the gimbal may perform an initial self-calibration. Ensure the gimbal is on a stable, level surface during this process.
5. Operation
Once the gimbal is set up, you can begin operating it to enhance your FPV experience.
5.1 Head Tracking Functionality
When paired with Avatar HD goggles, the gimbal utilizes head tracking. This means the camera's movement will synchronize with your head movements, providing an intuitive and immersive control experience. Look left, and the camera pans left; look up, and it tilts up, creating a feeling of being directly in the cockpit.
5.2 Control Modes and Sensitivity
You can manage the gimbal's modes and sensitivity through two primary methods:
- Avatar Goggles Menu: Access the settings menu within your Avatar HD goggles to adjust gimbal parameters. This allows for on-the-fly adjustments to suit your flying style and environmental conditions.
- PWM Controls: For advanced users, the gimbal supports PWM (Pulse Width Modulation) controls, allowing integration with your flight controller or remote control system for precise manual adjustments of gimbal behavior. Refer to your flight controller documentation for PWM setup.
6. Maintenance
To ensure the longevity and optimal performance of your CADDXFPV gimbal, follow these maintenance guidelines:
- Cleaning: Regularly clean the gimbal and camera lens with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Inspection: Periodically inspect all connections, cables, and mounting points for any signs of wear, damage, or looseness.
- Storage: Store the gimbal in a dry, dust-free environment when not in use. Protect it from extreme temperatures and direct sunlight.
- Avoid Impact: Gimbals are precision instruments. Avoid dropping or subjecting the gimbal to strong impacts, as this can affect its calibration and functionality.
7. Troubleshooting
7.1 Gimbal Not Functioning / Head Tracking Issues
- Check VTX Compatibility: Ensure your VTX is compatible with the GM series gimbals.
- Compatible VTX: V2 VTX, V2 VTX Dual, Moonlight VTX.
- Incompatible VTX: V1 VTX, Mini 1s, Nano V3, GT VTX.
- Verify Connections: Double-check all cable connections between the gimbal, camera, VTX, and power source. Ensure they are secure and correctly oriented.
- Power Supply: Confirm the gimbal is receiving adequate power within the 7-26V range.
- Goggles Pairing: Ensure your Avatar HD goggles are correctly paired and configured for head tracking.
7.2 Unstable or Jerky Footage
- Secure Mounting: Ensure the gimbal is securely mounted to your platform and there is no excessive vibration from the platform itself.
- Gimbal Calibration: If available, perform a gimbal calibration through the Avatar goggles menu or dedicated software.
- Environmental Factors: Strong winds or extreme maneuvers can sometimes exceed the gimbal's stabilization capabilities. Adjust flying style accordingly.
