1. Introducció
The Flysky FS-TH9X is a 2.4GHz 9-channel transmitter designed for RC helicopters, airplanes, and gliders. It utilizes the Automatic Frequency Hopping Digital System (AFHDS) developed by Flysky, offering robust anti-jamming capabilities, low power consumption, and high receiver sensitivity. Operating at 2.4 GHz, this system minimizes interference from other electronic components in your RC model, ensuring reliable control.
This manual provides essential information for setting up, operating, and maintaining your FS-TH9X transmitter and its accompanying 8-channel receiver (R9B).

3. Configuració
3.1 Powering the Transmitter
- Locate the battery compartment on the back of the FS-TH9X transmitter.
- Insert eight (8) 1.5V AA batteries, ensuring correct polarity. The transmitter requires 12V DC power.
- Tanqueu el compartiment de la bateria de manera segura.
- The transmitter also features a charger port for use with compatible rechargeable batteries and chargers (charger not always included).

3.2 Binding the Receiver (R9B)
Binding is the process of electronically linking the transmitter to the receiver, allowing them to communicate. This procedure typically needs to be performed only once per receiver.
- Assegureu-vos que el transmissor estigui apagat.
- Connect the binding plug to the B/VCC port on the R9B receiver.
- Apply power to the receiver (e.g., connect it to an ESC with BEC or a separate receiver battery). The receiver's LED should flash rapidly, indicating it is in binding mode.
- While holding down the "BIND" button (if present, or follow specific power-on sequence for binding) on the transmitter, power on the transmitter.
- The receiver's LED should stop flashing and remain solid, indicating successful binding.
- Apagueu tant l'emissor com el receptor.
- Remove the binding plug from the receiver.
- Power on the transmitter first, then the receiver. The receiver's LED should illuminate solid, confirming the link.

3.3 DSC Port
The DSC (Direct Servo Control) port allows for connection to flight simulators or other external devices for training or configuration purposes. Refer to your simulator's manual for specific connection instructions.
4. Operating the Transmitter
4.1 Controls bàsics i pantalla
The FS-TH9X features a 128x64 dot LCD screen for displaying settings and telemetry data. Navigation through menus is typically done using the scroll-pad and selection buttons.
The transmitter provides 9 channels for controlling various functions of your RC model. The modulation type is GFSK (Gaussian Frequency Shift Keying), and it operates with a sensitivity of 1024.
4.2 Funcions avançades
The FS-TH9X offers a comprehensive suite of programmable functions to fine-tune your model's performance:
- Throttle Curves: Adjust the throttle response at different stick positions.
- Pitch Curves: Modify the pitch response for helicopters.
- Endpoint Adjustments: Estableix el recorregut màxim per a cada servo.
- Subtalla: Make fine adjustments to servo neutral positions.
- Swash AFR Mixes: Advanced mixing for helicopter swashplate control.
- Inversió del servo: Change the direction of servo travel.
- Temporitzador: Built-in timer for flight duration tracking.
- Tarifa dual: Adjust the sensitivity of control surfaces (e.g., aileron, elevator, rudder) for different flight conditions.
- Exponencial: Soften the control response around the center stick position.
- Flaperons: Mix aileron and flap functions for enhanced control.
- V-Tail Mixing: Mix elevator and rudder for V-tail aircraft.
- Elevons: Mix elevator and aileron for delta wing aircraft.
Detailed instructions for configuring these functions can be found within the transmitter's menu system. Refer to the on-screen prompts and the included manual for specific navigation.
5. Manteniment
5.1 Atenció general
- Mantingueu el transmissor net i lliure de pols i humitat. Utilitzeu un drap suau i sec per netejar-lo.
- Avoid exposing the transmitter to extreme temperatures or direct sunlight for prolonged periods.
- Store the transmitter in a safe place to prevent physical damage.
5.2 Gestió de la bateria
- Always remove batteries from the transmitter if it will not be used for an extended period to prevent leakage.
- The transmitter features a low voltage warning system. When the battery voltage drops below a safe operating level, an alert will be displayed on the LCD screen. Replace or recharge batteries immediately when this warning appears to avoid loss of control.
- Use only high-quality 1.5V AA batteries or a compatible rechargeable battery pack with the correct voltage.
6. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El transmissor no s'encén. | Incorrect battery installation, dead batteries. | Comproveu la polaritat de la bateria. Substituïu-la per bateries noves. |
| Receiver LED not solid after binding. | Binding failed, transmitter/receiver too far apart, interference. | Repeat the binding procedure carefully. Ensure transmitter and receiver are close during binding. Check for strong interference sources. |
| Loss of control during operation. | Low transmitter battery, excessive range, strong interference. | Check transmitter battery voltage. Operate within recommended range. The AFHDS system provides strong anti-jamming, but extreme interference can still affect performance. |
| Controls are reversed or incorrect. | Incorrect servo reversing settings, wrong model type selected. | Adjust servo reversing in the transmitter menu. Verify the correct model type (helicopter, airplane, glider) is selected. |
| LCD screen is dim or unreadable. | Low battery, contrast setting. | Check transmitter battery. Adjust LCD contrast settings in the menu. |
