Setup

Proper installation and calibration are crucial for the optimal performance of your Spektrum GPS Module. Follow these steps carefully:

1. Physical Installation: Secure the GPS module within your aircraft. For models like the Carbon Cub, it typically fits into a designated notch. Ensure it is firmly secured to prevent dislodgement during flight. Users often use tape for additional security.
2. Connection: Connect the GPS module to the flight controller. Be mindful of the port location and ensure a secure connection, as wires can easily be pulled out.
3. Initial GPS Lock: Power on your transmitter first, then your aircraft. The aircraft will enter GPS seeking mode, indicated by the elevator wagging slowly. Once a GPS lock is acquired, the elevator will wag faster.
4. Compass Calibration: After GPS lock, the aircraft will enter compass calibration mode. Follow the specific instructions provided with your aircraft for this process. A common method involves holding the aircraft nose downward for approximately five seconds, then flipping it nose over nose, and finally rolling it horizontally. Ensure the transmitter is turned off first, then the receiver, for the calibration to be accepted.

Operating Instructions

The Spektrum GPS Module enhances your flying experience with several intelligent features:

• Setting Home Position: Once the aircraft has achieved GPS lock and is ready for takeoff, hold down the bind button on your transmitter. The aircraft's control surfaces will wag to confirm the home position has been set. Ensure the aircraft is pointed straight down the runway for accurate autoland functionality.
• Virtual Fence: This feature prevents the aircraft from flying too far away. If the aircraft approaches the boundary of the virtual fence, it will automatically turn back. The airplane will rock its wings to indicate that you have regained control.
• Holding Pattern: Pause your flight by pushing a designated button on your transmitter. The aircraft will enter a holding pattern at a safe altitude (e.g., 120 feet). Push the button again to cancel the command and resume manual control.
• Autoland: To initiate autoland, push and hold the designated button on your transmitter. The aircraft will automatically land near the takeoff location. The accuracy of the landing depends on the precisely set home position.

Maintenance

To ensure the longevity and reliable performance of your Spektrum GPS Module, consider the following maintenance guidelines:

• Keep Dry: Protect the module from moisture and extreme humidity.
• Clean Connections: Periodically inspect and clean all electrical connections to prevent corrosion and ensure optimal signal transmission.
• Inspect for Damage: Regularly check the module and its wiring for any signs of physical damage, such as cracks, frayed wires, or loose components.
• Secure Mounting: Verify that the module remains securely mounted within the aircraft to prevent vibrations or impacts from affecting its performance.

Troubleshooting

If you encounter issues with your Spektrum GPS Module, consider these troubleshooting steps:

• No GPS Lock: Ensure the aircraft has a clear view of the sky and is not obstructed by buildings or dense foliage. Allow sufficient time for initial GPS acquisition.
• Inaccurate Calibration: Re-perform the compass calibration procedure carefully, ensuring all steps are followed in the correct order, especially the transmitter and receiver power-off sequence.
• Module Malfunction: If the module stops working or exhibits erratic behavior, check all connections for looseness or damage. If issues persist, contact customer support.
• Interference: Ensure the module is not placed too close to other electronic components that might cause signal interference.
