5. Safety Warnings & Disclaimer

⚠️ WARNINGS: Read this user manual before use.

• The user needs to have relevant professional knowledge when operating the VTX product. Any illegal use may cause potential dangers.
• Please pay attention to the relevant laws and regulations on the use of radio equipment, or operate under the guidance of professionals. The user assumes responsibility for any personal injury or property damage resulting from improper use.
• The VTX will generate a lot of heat while normal working. Please ensure adequate airflow to provide a well-ventilated mounting position.
• Ensure all cables and plugs are installed correctly. Before powering up, please ensure the antenna has been installed and firmly connected. Never power on the device without an antenna, as this may damage the VTX or cause a breakdown.
• Do not modify this product without authorization. Contact your dealer for technical support when the VTX breaks down.
• Please follow the local radio regulations. A HAM license is required for operating on HAM channels.
• Please also pay attention to the relevant laws and regulations on the use of drones/planes in your country/area to ensure legal use.

Disclaimer:

For recreation use only. Illegal modification of drones/planes is prohibited. Please also pay attention to the relevant laws and regulations on the use of drones/planes in your country/area to ensure legal use.

6. Preparation Before Installation

Before proceeding with the installation, please confirm the following points:

• Ensure the flight battery voltage matches the product's power requirements.
• Verify that a compatible FPV antenna is available.
• Confirm that the flight controller, camera, and video transmitter are connected correctly according to your setup.
• Ensure the chosen installation area has good ventilation to facilitate heat dissipation.
• Confirm that all mounting accessories are secure to prevent loosening during flight.

7. Installation Method

1. Securely fix the video transmitter to a suitable location on your drone's frame. Prioritize a well-ventilated area to aid in cooling.
2. Connect the power cable, ensuring correct positive and negative polarity. Incorrect connection can damage the unit.
3. Connect the camera's video signal output to the VTX's video input port.
4. If your setup supports remote control adjustment (e.g., SmartAudio), connect the control wire according to your flight controller's wiring diagram and the VTX's product version.
5. Install the FPV antenna and ensure it is firmly connected to the VTX. Crucially, never power on the device without an antenna connected, as this will damage the unit.
6. Before powering on the entire system, carefully check all solder joints and plugs for secure connections and correct wiring.

8. Operating Instructions

1. After completing the installation, double-check that the antenna is properly connected.
2. Power on the device and confirm that the transmission indicator light is working normally.
3. Turn on your FPV receiver and select the same frequency band and channel as set on the VTX.
4. Check if the video image is displayed correctly on your FPV goggles or monitor. If interference is present, try adjusting the channel.
5. It is highly recommended to perform a short ground test before actual flight to ensure stable signal performance and prevent unexpected issues during flight.

9. Channel and Power Adjustment

The RushFPV MAX SOLO supports multiple video transmission channels. Users can switch channels according to the receiver display or OSD menu.

High-power mode is suitable for long-distance FPV flights. However, for ground testing, it is recommended to use low or medium power settings to minimize interference and reduce heat generation.

Note: The specific channel switching method may vary depending on the product version and firmware. Always operate according to the instructions provided with your specific version.

10. Precautions

• Never power on the device without an antenna connected. This can cause irreversible damage to the VTX unit.
• Always disconnect the main power source before performing any installation or adjustment to avoid short circuits.
• Do not exceed the rated operating voltage of the product. Refer to specifications for input voltage range.
• If the device becomes excessively hot during use, improve cooling (e.g., add more airflow) or temporarily cease operation to prevent damage.
• Avoid using the product in wet, high-temperature, or strong electromagnetic interference environments.
• This product is recommended for users who have prior FPV installation and operation experience.
• Always follow local laws and airspace regulations before and during flight.

11. Troubleshooting (FAQ)

1. No video output

• Check if the camera power supply is normal.
• Verify that the video cable is connected correctly between the camera and VTX.
• Ensure the receiver channel matches the VTX channel.
• Confirm that the antenna is installed and tightened securely.

2. Unstable image or interference

• Try switching to a different channel.
• Check if the antenna is damaged and replace if necessary.
• Keep the VTX away from strong electromagnetic interference sources.
• Ensure the power supply is stable; low voltage can cause image problems.

3. The device becomes hot

• High-power operation naturally generates noticeable heat. This is normal.
• It is recommended to improve cooling or ensure adequate ventilation around the VTX.
• Avoid continuous full-power operation during extended ground tests.

12. Maintenance and Storage

• After use, turn off the power and allow the device to cool down completely before handling or storing.
• Regularly check the antenna connector, power plugs, and solder joints for any signs of looseness or damage.
• When not in use for an extended period, store the product in a dry and well-ventilated place.
• Avoid strong impacts or dropping the metal shell, as this can cause internal damage.

13. User Tips

• Antenna Placement: Position your antenna away from other electronics and carbon fiber parts of your drone to minimize signal interference and maximize range.
• Power Output Management: While the VTX offers high power, use the lowest effective power setting for your flight conditions to reduce heat and conserve battery. Only use MAX power when absolutely necessary for long-range flights.
• Cooling is Key: Ensure constant airflow over the VTX, especially during high-power operation. Consider adding a small dedicated fan or optimizing drone layout for better ventilation if overheating is a concern.
• SmartAudio Configuration: Familiarize yourself with SmartAudio for convenient channel and power adjustments directly from your flight controller's OSD.
