RUSH TANK MAX SOLO 5.8GHz VTX User Manual

1. Introduction

The RUSH TANK MAX SOLO is a high-power 5.8GHz Video Transmitter (VTX) designed for RC FPV long-range fixed-wing drones and DIY projects. It features a compact design with active cooling to ensure full performance, LOCK-ON technology for stable transmission, and factory power consistency calibration.

Important Warnings

• The user needs to have relevant professional knowledge while mounting or operating the VTX product. Improper use may cause severe damage to the product and even personal injury.
• Before operating the VTX, you must install the antenna and ensure you review the local regulations.
• The VTX will generate a lot of heat during normal operation. Ensure adequate airflow to dissipate heat.
• All cables and plugs must be installed correctly before powering up.
• Ensure the antenna has been installed before powering up, otherwise the amplifier will burn out.
• Do not disassemble, repair, or modify this product personally. Contact your dealer for technical support.

4. Setup and Wiring

Proper wiring is crucial for the safe and effective operation of your RUSH TANK MAX SOLO VTX. Refer to the diagram below for connection details.

Wiring Connections:

• Power Input: Connect DC 7-36V (6S LIPO) to the VTX power input.
• Video Input: Connect your camera's video output to the 'VIDEO IN' pad on the VTX.
• Audio Input: Connect your microphone's audio output to the 'AUDIO' pad on the VTX.
• 5V Output: The '5V OUT' provides up to 500mA for camera use only. Do not connect this to the power input or battery, as it will damage the VTX.
• SmartAudio: Connect the 'DATA' pad on the VTX to a free UART-TX pad on your Flight Controller for external control.
• Antenna: Connect the MMCX antenna to the VTX. Ensure the antenna is securely installed before powering on the VTX to prevent damage to the RF amplifier.

5. Operating Instructions

Manual Button Operation:

• Channel/Band Button:
  • Press briefly to set the channel.
  • Press and hold to set the band.
• Power Button:
  • Press briefly to set the power level.
  • Press and hold to toggle ON/OFF mode.

SmartAudio Setup and Operation:

SmartAudio allows for convenient VTX control via your flight controller and OSD.

1. Connect SmartAudio: Connect the 'DATA' port of the VTX to a free UART-TX pad on your flight controller.
2. BetaFlight Configuration:
   • Open the BetaFlight configurator.
   • Navigate to the 'Ports' tab.
   • Under 'Peripherals' next to the UART connected to the VTX's RX pad (which is the 'DATA' line from the VTX), select 'TBS SmartAudio'. The speed can typically be left at <auto>.
   • Save the settings.
3. OSD Menu Access:
   • Turn on your radio control.
   • Move the throttle to the middle, yaw left, and pitch up to enter the OSD menu.
4. VTX SA Menu:
   • In the OSD, navigate to the 'Function' > 'VTX SA' menu to set the VTX working state.
   • Config Menu:
     • If set to 'RACE' mode, the VTX will automatically enter PIT mode after rebooting.
     • If set to 'FREE' mode, the VTX will only transmit after booting.
     • After switching the working mode, you need to reconnect the power to apply the new settings.

6. Maintenance

• Cooling: The VTX generates significant heat. Always ensure it is installed in a location with adequate airflow to prevent overheating and ensure optimal performance. Do not block the airflow duct of the high-efficiency cooling fan.
• Antenna Care: The RF amplifier is highly sensitive to Standing Wave Ratio (SWR), especially at high power outputs. Always ensure the antenna is properly installed and in good condition. Damaged antennas or coaxial cables can lead to amplifier failure.
• Cable Integrity: Regularly inspect all power and signal cables for wear, damage, or loose connections.

7. Troubleshooting

• VTX Amplifier Burn Out: This typically occurs if the VTX is powered on without an antenna connected, especially at high power. Always ensure the antenna is securely attached before applying power.
• Low Power Output: If the VTX is not connected to SmartAudio, it will default to the lowest power output even if it starts. Ensure SmartAudio is correctly configured if you require higher power levels.
• No Video Signal: Check all video input and output connections. Verify the camera is powered and functioning. Ensure the VTX is powered correctly.
• Interference/Poor Video Quality: Check for proper cooling, as overheating can degrade performance. Ensure all cables are shielded and properly routed away from noise sources. Verify antenna condition and connection.

8. User Tips

• The RUSH TANK MAX SOLO is praised for its compact size (40x24x10.5mm) and durable composite material construction, making it suitable for various drone builds.
• Its primary functions include remote control and video transmission, essential for FPV flying.
• Leverage the active cooling design by ensuring good airflow around the VTX, especially during high-power operation, to maintain optimal performance and longevity.
