5. Setup

5.1 Transmitter Battery Installation

1. Locate the battery compartment on the handle of the CT-10B transmitter.
2. Open the battery compartment cover.
3. Insert one 18650 battery (not included) into the compartment, ensuring correct polarity.
4. Close the battery compartment cover securely.

The transmitter supports charging via the USB port using the provided charging cable. Connect the charging cable to the transmitter's charging port and a suitable USB power source.

5.2 Receiver Connection

Connect the F-10A receiver to your model's electronic speed controller (ESC), servos, and other components according to your model's specific wiring diagram. Ensure correct polarity for all connections.

• Connect the ESC to Channel 2 (throttle).
• Connect the steering servo to Channel 1.
• Connect other servos or accessories to Channels 3-10 as required.
• If using the feedback function, connect the provided voltage cable to the receiver's feedback port and to the main battery of your model.

5.3 Binding the Transmitter and Receiver

The CT-10B transmitter and F-10A receiver are typically pre-bound from the factory. If re-binding is necessary or if you are using a new receiver, follow these steps:

1. Ensure both the transmitter and receiver are powered off.
2. Connect a bind plug (not included, usually comes with the receiver or ESC) to the BIND/VCC port on the F-10A receiver.
3. Power on the receiver. The receiver's LED should flash rapidly, indicating it is in binding mode.
4. While holding down the BIND button on the CT-10B transmitter (refer to the diagram for location, usually near the power button or on the side), power on the transmitter.
5. The transmitter's screen should display a binding progress or confirmation message. The receiver's LED should turn solid, indicating successful binding.
6. Power off both the transmitter and receiver.
7. Remove the bind plug from the receiver.
8. Power on the transmitter first, then the receiver. Verify that the controls respond correctly.

6. Operation

6.1 Power On/Off

• To Power On: Long press the Power button on the transmitter until the screen illuminates.
• To Power Off: Long press the Power button until the screen shuts down.

6.2 Basic Controls

• Steering: Use the direction joystick (steering wheel) to control the left/right movement of your model.
• Throttle: Use the throttle trigger to control forward and reverse movement. Pull the trigger for forward, push for reverse/brake.
• Auxiliary Channels: Use the VRB, VRA potentiometers and SWB, SWA switches to control auxiliary functions on your model, such as lights, winches, or gear shifts, depending on your model's setup.

6.3 Menu Navigation and Settings

The CT-10B features a user-friendly interface for adjusting parameters. Use the scroll wheel button and the A, B, C, D buttons to navigate and modify settings.

• Scroll Wheel Button: Rotate to scroll through menu options. Press to select an option or confirm a setting.
• Power Button (Short Press): Acts as a "Return" or "Exit" button in menus.
• A, B, C, D Buttons: These are programmable buttons. Their functions may vary depending on the selected menu or model profile. Refer to the on-screen prompts for their current assignments.

The UI allows for real-time adjustment of parameters such as channel endpoints, sub-trim, reverse, and mixing functions. The screen displays real-time feedback like receiver voltage and signal strength.

6.4 Advanced Functions

• Trainer Function: The CT-10B supports a trainer mode, allowing two transmitters to control one model. This is ideal for teaching new users. A data connection line (not included) is required to link two CT-10B transmitters.
• Speed Cruise Function: Enables a constant speed setting for your model, reducing the need for continuous throttle input. Activate and adjust via the menu.
• Fail-Safe Function: Configures the receiver to move servos to a pre-set position (e.g., throttle to neutral, steering straight) in case of signal loss, preventing runaway models. Set fail-safe positions through the transmitter menu.
• Receiver Feedback Function: The F-10A receiver can transmit battery voltage and signal strength back to the transmitter, displayed on the screen. The feedback alarm voltage can be set in the transmitter's menu.
• Gyro Stabilization: For models requiring gyro stabilization, pair the CT-10B with a compatible receiver like the F-08AT (sold separately) for enhanced handling.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or abrasive cleaners.
• Storage: Store the product in a cool, dry place away from direct sunlight and extreme temperatures. Remove the 18650 battery from the transmitter if storing for extended periods.
• Battery Care: Ensure the 18650 battery is charged regularly, even during storage, to maintain its lifespan. Do not overcharge or deep discharge the battery.
• Firmware Updates: Check the manufacturer's website for any available firmware updates for improved performance or new features.

8. Troubleshooting

• No Power to Transmitter:
  • Ensure the 18650 battery is correctly installed with proper polarity.
  • Check if the battery is charged. Connect the charging cable and attempt to power on.

  • Verify that the transmitter and receiver are properly bound. Re-bind if necessary (refer to Section 5.3).
  • Check all connections between the receiver, ESC, and servos.
  • Ensure both the transmitter and receiver are powered on.
  • Check the receiver's LED indicator; it should be solid after binding.
  • Confirm the model's battery is charged and connected.
• Short Control Range or Signal Interference:
  • Ensure the transmitter antenna is not obstructed.
  • Avoid operating in areas with strong electromagnetic interference.
  • Check for physical obstructions between the transmitter and receiver.
  • Ensure the receiver antenna is properly positioned and not damaged.
• Incorrect Channel Response:
  • Check channel assignments and reverse settings in the transmitter menu.
  • Ensure servos are connected to the correct receiver ports.
