Please read this manual thoroughly before installation and operation to ensure optimal performance and safe use.

2. Safety Warnings

⚠ WARNING: Read this user manual before use.

• The user needs to have relevant professional knowledge while mounting or operating the VTX product. Any illegal use may cause potential danger. Please ensure that you have the skills of operating radio equipment, or operate under the guidance of a professional.
• This product can expose you to chemicals including phthalates (DEHP), which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
• This product is a dedicated video transmitter for FPV drone racing. It is strictly prohibited to use it for illegal radio transmission, peeping, voyeurism, and other illegal activities.
• Before powering up, the user shall ensure the antenna and all other components have been installed properly. The VTX will generate a lot of heat under normal operating conditions. To prevent overheating, provide constant airflow and a well-ventilated environment.
• Do not disassemble or modify the product to avoid potentially damaging the VTX. Contact your local dealer for any technical support.
• The drone power must be turned off during installation and disassembly. Live operation is strictly prohibited to avoid short circuits damaging the drone circuit or VTX.
• Avoid the VTX being subjected to severe collision, extrusion, bending, and do not scratch the surface with sharp objects, otherwise it will cause signal attenuation and damage.
• Do not use it in thunderstorm weather or strong electromagnetic interference environments (such as near high-voltage electricity, radar stations) to avoid signal interference or lightning damage to the equipment.
• When used by minors, it must be operated under adult supervision to avoid equipment damage or personal injury caused by incorrect operation.

3. Product Overview & Features

The RUSHFPV TANK series VTX modules are designed for high-performance FPV applications, offering robust features for competitive racing and freestyle flying.

General Features:

• Lock-on Technology: New designed locked frequency circuit coordinates software optimization, enabling the transmitting frequency to maintain its set point in harsh, high-interference environments. Allows multiple drones to race in the same band without interference.
• Power LUT (Lookup Table): Built-in high-precision power lookup table performs milliwatt power calibration for all channels. Each full band has its own unique power output, ensuring fair and consistent signal for all pilots in multi-pilot flights.
• Silent Setting: The intelligent transmit circuit does not generate any interference signal during VTX switching and setting. With PITMODE, you can set the VTX anytime and anywhere without disturbing others.
• SmartAudio Protocol: Built-in SmartAudio protocol (authorized by TBS) allows VTX information to be set up and viewed via the OSD menu. Can also be set with RGB LED via conventional double buttons.
• PIT Mode: After entering PITMODE, the VTX power is reduced to a minimum. Your video feed is only visible to yourself at close range, preventing interference with other pilots.

5. Installation

Note: Before installation, ensure the drone is completely powered off to avoid short circuits or signal interference. Handle with care to prevent damage to the VTX and drone interface.

5.1. General Installation Steps

1. Interface Matching: Identify the antenna interface type on your drone (SMA/MMCX/UFL) and select the corresponding VTX connector or adapter. Ensure compatibility before proceeding.
2. Polarization Mode Selection: If your VTX supports LHCP/RHCP polarization, select the mode that matches your FPV receiver for optimal signal transmission. The corresponding mode mark is usually on the VTX surface.
3. Mounting: Align the VTX or its adapter with the drone's interface. Gently rotate clockwise to tighten until it is firmly fixed. Do not overtighten to avoid damaging the interface. If using an adapter, secure the adapter to the drone first, then connect the VTX to the adapter.
4. Installation Inspection: After mounting, gently shake the VTX to confirm it is secure. Ensure all connection cables are neatly arranged and clear of propellers, motors, and other moving parts to prevent interference with normal flight.

5.2. Wiring Diagrams

Refer to the specific wiring diagrams for your VTX model. Always ensure correct polarity and voltage to prevent damage.

5.3. Soldering PCB (RUSH TANK III Ultimate Example)

For models like the RUSH TANK III Ultimate, follow these steps for PCB soldering:

1. Step 1: Soldering PCB. Solder the VTX to the expanding board, then connect to Crossfire Nano RX if applicable.
2. Step 2: Check pad soldering. Verify all solder joints for the VTX switch, fixing holes, WS2812 LED, and camera pad.
3. Step 3: Connect to Flight Controller. Wire the VTX to your Flight Controller (FC) as per the diagram, ensuring correct connections for VTX, Camera, SmartAudio, and power.

6. Operation

6.1. Power-On Inspection

Before powering on the drone, confirm the VTX is firmly installed, the interface is not loose, the polarization mode matches the receiver, and there is no large-area metal obstruction around the VTX (metal can interfere with signal transmission).

6.2. VTX Button Operation (RACE2, TANK Tiny, TANK III Ultimate)

The VTX typically features buttons for manual control of channels, bands, and power levels. Refer to the specific model's diagram for button functions.

• Channel Setting: Hold the button to enter setting mode (Red Channel LED blinks). Press the button to cycle through channels 1-8.
• Band Setting: Hold the button to move to the next setting (Blue Band LED blinks). Press the button to cycle through bands 1-6.
• Power Level Setting: Hold the button to move to the next setting (Green Power LED blinks). Press the button to cycle through power levels (e.g., 1-4 PWR levels).
• Save and Exit: Hold the button to save settings and exit.
• PIT Mode ON/OFF: Double-click the button to toggle PIT mode.

6.3. SmartAudio Configuration

RUSH TANK VTX modules feature SmartAudio for convenient configuration via your Flight Controller (FC) and OSD (On-Screen Display).

1. Connect SmartAudio: Connect the SmartAudio port on the VTX to a free UART-TX port on your Flight Controller.
2. BetaFlight Configuration: Open BetaFlight configurator. Go to the Ports tab, find the UART port connected to SmartAudio, and select 'TBS SmartAudio' from the Peripherals dropdown menu. Speed can be left at AUTO. Save the settings.
3. OSD Menu Access: Turn on your radio control. Center the throttle (THR middle), move yaw left, and pitch up to enter the OSD menu.
4. VTX SA Menu: In the Function > VTX SA menu, set the VTX working state. In the CONFIG menu, setting to RACE mode will automatically boot the VTX in PIT mode. Setting to FREE mode will allow the VTX to transmit normally after booting. After switching modes, you need to reconnect power for settings to take effect.

7. Maintenance

7.1. Daily Maintenance

• After each use, wipe the VTX surface and interface with a dry, soft cloth to remove dust and stains.
• Check if the VTX cable is damaged or broken, and if the interface is loose. If any problem is found, stop using it immediately and replace it.

7.2. Storage Method

• When not in use, remove the VTX from the drone and store it in a dry, ventilated, and cool environment.
• Avoid moisture, high temperature, exposure to sunlight, and extrusion.
• Avoid placing it with corrosive substances and sharp objects.

7.3. Regular Inspection

• Check the VTX performance every 1-2 months.
• If signal transmission is unstable, severely attenuated, or the interface is oxidized or loose, replace the VTX or adapter in time.

8. Troubleshooting

• Signal Instability/Attenuation: Check all connections, ensure the antenna is securely attached and undamaged. Verify polarization mode matches the receiver. If issues persist, replace the VTX or antenna.
• Overheating: If the VTX overheats (indicated by orange light flashing quickly), the power level will automatically drop. Allow the VTX to cool down. Ensure adequate airflow and ventilation around the VTX.
• No Video Signal: Check power connections, video input/output connections, and ensure the VTX is not in PIT mode unintentionally.

9. User Tips

• Always perform a range check before flying, especially after any changes to your FPV system.
• Keep your VTX firmware updated if applicable, as manufacturers often release improvements.
• Consider using a small heatsink or active cooling (fan) for higher power settings or in enclosed environments to prevent overheating.
• When flying with multiple pilots, coordinate VTX channels and power levels to minimize interference.
