4. Setup

4.1. Transmitter Battery Installation

1. Locate the battery compartment on the back of the FS-i4 transmitter.
2. Press the release tab and slide open the battery cover.
3. Insert four (4) AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery cover until it clicks securely into place.

4.2. Receiver Connection

Connect the FS-A6 receiver to your RC model's electronic speed controller (ESC) and servos according to your model's specific wiring diagram. Refer to Image 3.3 for a general connection overview.

• Connect the ESC (providing power and throttle signal) to the 'THR' (Throttle) channel on the receiver.
• Connect servos for Aileron, Elevator, and Rudder to their respective channels (AIL, ELE, RUD).
• Ensure all connections are secure and correctly oriented.

4.3. Binding Procedure

Binding is the process of linking the transmitter and receiver so they can communicate. This procedure is typically done once per transmitter-receiver pair.

1. Ensure the transmitter is OFF.
2. Connect the bind plug (included with the receiver) to the 'BIND' port on the FS-A6 receiver.
3. Power on the receiver (e.g., by connecting the ESC to the battery). The receiver's LED should flash rapidly.
4. While holding down the 'BIND KEY' button on the FS-i4 transmitter, turn on the transmitter.
5. Release the 'BIND KEY' button after the transmitter powers on. The receiver's LED should now be solid, indicating successful binding.
6. Turn off both the transmitter and receiver.
7. Remove the bind plug from the receiver.
8. Power on the transmitter first, then the receiver. The receiver's LED should be solid, confirming the link.

5. Operating Instructions

5.1. Basic Controls

The FS-i4 transmitter features two primary control sticks (gimbals) and various switches for controlling your RC model.

• Left Gimbal: Typically controls throttle (vertical movement) and rudder (horizontal movement).
• Right Gimbal: Typically controls elevator (vertical movement) and aileron (horizontal movement).
• Trims: Small sliders or buttons near each gimbal used for fine-tuning the neutral position of the control surfaces. Adjust trims to ensure the model flies straight and level without stick input.
• Reverse Switches: Located on the front panel, these switches (V-MIX, RUD, THR, ELE, AIL) allow you to reverse the direction of a specific channel's output if a control surface moves in the opposite direction desired.

5.2. Powering On/Off

1. To Power On: Always turn on the transmitter first. Ensure the throttle stick is at its lowest position.
2. To Power Off: Always turn off the receiver/model first, then turn off the transmitter. This prevents accidental runaway of the model.

6. Maintenance

Proper maintenance will ensure the longevity and reliable operation of your radio system.

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Do not use solvents or abrasive cleaners.
• Storage: Store the radio system in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if storing for extended periods.
• Inspection: Periodically inspect all cables, connectors, and the antenna for any signs of wear or damage. Replace damaged components immediately.
