3. Specifications

3.1. Transmitter (CT-6B)

*Note: The remote control distance is for reference only, and the actual use will vary according to different environments.

3.2. Receivers (F-Series)

The CT-6B transmitter is compatible with various F-series receivers. Below are the specifications for common models:

*Note: Remote control distance for receivers is typically 300-800m on the ground and 800m in the air. Actual use may vary.

4. Components

The HOTRC CT-6B system typically includes:

• HOTRC CT-6B 8CH Transmitter
• One compatible F-series PWM Receiver (e.g., F-08A, F-08AT, F-01A, F-01AT, F-04A, F-04AT, F-06A, F-06AT)

Please check your package contents against the product description to ensure all components are present.

5. Setup

5.1. Battery Installation (Transmitter)

1. Locate the 18650 battery compartment on the bottom of the transmitter handle.
2. Insert a fully charged 18650 lithium battery (not included) into the compartment, ensuring correct polarity.
3. Close the battery compartment cover securely.

The transmitter can be charged directly via its Type-C interface using a standard USB charger (not included).

5.2. Receiver Connection and Binding

The remote control comes standard with an F-08A eight-channel receiver. Other receiver models can be purchased separately.

1. Connect Servos/ESCs: Connect your model's servos, Electronic Speed Controllers (ESCs), and other components to the corresponding PWM channels on the receiver. Refer to your model's specific wiring diagram for correct connections.
2. Power the Receiver: Provide power to the receiver (DC 3.5V-9V) from your model's power system.
3. Binding Process:
   • Ensure both the transmitter and receiver are powered off.
   • Connect the 'BIND' plug (if provided with your receiver) to the BIND port on the receiver.
   • Power on the receiver. The receiver's LED should indicate it's in binding mode (e.g., flashing rapidly).
   • Turn on the CT-6B transmitter while holding down the binding button (if applicable, otherwise power on normally).
   • The receiver's LED should turn solid, indicating a successful bind.
   • Power off both the transmitter and receiver. Remove the BIND plug from the receiver.
   • Power on the transmitter first, then the receiver. Test controls to confirm successful binding.
4. Voltage Return Line (for F-08A and similar): If your receiver supports voltage return, connect the dedicated return line to the EXT-V port on the receiver and the other end to the battery or voltage source you wish to monitor.

6. Operating Instructions

6.1. Basic Controls

• Power On/Off: Press and hold the power button to turn the transmitter on or off.
• Throttle Trigger: Controls forward/reverse movement or speed.
• Directional Rocker (Steering Wheel): Controls left/right steering.
• Channel Buttons (CH5, CH6, etc.): Use the various buttons and knobs (VRA, VRB) to control auxiliary channels as configured for your model.

6.2. Advanced Functions

• LCD Display Monitoring: The LCD screen displays real-time information such as transmitter battery voltage (T), receiver battery voltage (R), and signal strength.
• Electronic Trim: Use the trim buttons around the directional pad to fine-tune the neutral position of your steering and throttle channels.
• Mixed Control: Access the mixed control settings via the operation panel to configure complex control schemes for your model.
• Lock Function: Engage the lock function to prevent accidental changes to critical settings during operation.
• Stroke Adjustment: Adjust the maximum travel (stroke) for individual channels to match your model's requirements.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or harsh chemicals.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Remove the 18650 battery if storing for extended periods.
• Battery Care: Ensure the 18650 battery is charged regularly, even during storage, to maintain its lifespan.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates for improved performance or new features.

8. Troubleshooting

• No Power: Check the 18650 battery installation and charge level. Ensure the battery is correctly inserted with proper polarity.
• No Control/Loss of Signal:
  • Verify that the transmitter and receiver are properly bound. Re-bind if necessary.
  • Ensure both devices are powered on.
  • Check the remote control distance; operating beyond the specified range (300M ground / 800M air) can lead to signal loss.
  • Minimize interference from other 2.4Ghz devices or large metal objects.
• Runaway Protection: The system includes runaway protection. If your model behaves unexpectedly, ensure all connections are secure and re-check your binding and trim settings.
• Incorrect Channel Response: Check the positive and negative channel settings in the transmitter to ensure servos/ESCs respond in the correct direction.

9. User Tips

• Practice in an Open Area: Before operating your RC model in confined spaces, practice in an open area to get accustomed to the controls.
• Regular Checks: Always perform a pre-flight/pre-run check of all connections, battery levels, and control responses before operating your model.
• Battery Management: Keep spare charged 18650 batteries on hand for extended operation sessions.
• Environmental Awareness: Be mindful of your operating environment. While the FHSS technology provides good anti-interference, extreme conditions or dense urban areas might still affect performance.
