5. Configuração
5.1 Instalação da Bateria do Transmissor
- Locate the battery compartment on the handle of the CT-10B transmitter.
- Abra a tampa do compartimento da bateria.
- Insert one 18650 battery (not included) into the compartment, ensuring correct polarity.
- Feche bem a tampa do compartimento da bateria.
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 Conexão do Receptor
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 Emparelhamento do transmissor e do receptor
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:
- Certifique-se de que tanto o transmissor quanto o receptor estejam desligados.
- Connect a bind plug (not included, usually comes with the receiver or ESC) to the BIND/VCC port on the F-10A receiver.
- Power on the receiver. The receiver's LED should flash rapidly, indicating it is in binding mode.
- 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.
- The transmitter's screen should display a binding progress or confirmation message. The receiver's LED should turn solid, indicating successful binding.
- Power off both the transmitter and receiver.
- Remova o plugue de ligação do receptor.
- Power on the transmitter first, then the receiver. Verify that the controls respond correctly.
6. Operação
