4. Setup and Installation
The Electric Slip Ring is designed for integration into Henglong TK7.0 edition 1/16 RC Tanks. Installation typically involves connecting the slip ring to the tank's main control board and the turret's electrical components.
4.1. Preparation
- Ensure your RC tank is powered off and the battery is disconnected.
- Carefully open the tank's chassis to access the main control board and turret wiring. Refer to your tank's specific manual for disassembly instructions.
4.2. Connection Guide
The slip ring features a main connector board with labeled ports for various tank functions. Identify the corresponding ports on your Henglong TK7.0 control board.

Figure 4.1: Labeled connection points on the slip ring board.
Connect the slip ring's cables to the appropriate ports on your tank's control system. The common connections are:
- CN4: Barrel Lifting Gearbox
- CN10: BB Shooting Unit
- CN6: Tank Recoil
- CN16: Infrared Receiver
- CN15: Infrared Emitting Lamp
- LED5: Machine Gun Light
- FPV: First Person View Camera (if applicable)

Ensure each connector is firmly seated. The slip ring itself should be mounted in a position that allows for free 360-degree rotation without obstruction or excessive tension on the wires.
4.3. Post-Installation Check
- Before reassembling the tank, perform a preliminary test. Reconnect the battery and power on the tank.
- Test the turret's rotation and all connected functions (e.g., barrel lift, BB firing, lights) to ensure they operate correctly and smoothly through a full 360-degree rotation.
- If all functions work as expected, carefully reassemble your RC tank.
5. Operating the Slip Ring
The Electric Slip Ring operates passively, providing a continuous electrical pathway for signals and power as the RC tank's turret rotates. Once correctly installed, it requires no direct user interaction for its function. Its purpose is to enable the 360-degree rotation capability of your tank's turret without tangling or breaking wires.
6. Maintenance
The Electric Slip Ring is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Keep Clean: Periodically inspect the slip ring and its connections for dust, dirt, or debris. Use a soft, dry brush or compressed air to gently clean the component.
- Avoid Moisture: Protect the slip ring from water and high humidity, which can cause corrosion and electrical shorts.
- Inspect Wires: Regularly check the wires and connectors for any signs of wear, fraying, or damage. Replace the slip ring if significant damage is observed.
- Gentle Handling: Avoid applying excessive force or bending the wires sharply during installation or maintenance.
7. Troubleshooting
If you encounter issues after installing the slip ring, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Turret does not rotate 360 degrees or functions intermittently. | Incorrect or loose connections. Obstruction preventing full rotation. Damaged slip ring. | Verify all connections are secure and correctly plugged into the designated ports. Check for any physical obstructions within the tank's chassis. Inspect the slip ring for visible damage. |
| Specific turret functions (e.g., barrel lift, BB firing) are not working. | Incorrect connection for that specific function. Faulty component. | Refer to Figure 4.1 and ensure the specific function's connector (e.g., CN4 for barrel lift) is correctly attached. Test the individual component if possible. |
| No power to turret or connected components. | Main power issue. Slip ring not properly installed. | Ensure the tank's battery is charged and properly connected. Double-check all main power connections to and from the slip ring. |
If problems persist after following these steps, please contact TOUCAN RC HOBBY customer support.
