Specifications

Setup

1. Installation

Mount the FS-GR3E receiver securely in your RC model, ensuring it is protected from vibrations and moisture. Position the antenna wire as straight as possible and away from metal parts or carbon fiber chassis to maximize range and signal quality. Connect your Electronic Speed Controller (ESC) to Channel 2 (throttle), and your steering servo to Channel 1. If using a third channel for auxiliary functions, connect it to Channel 3.

2. Binding the Receiver to the Transmitter

The receiver must be bound to your Flysky transmitter before use. Follow these steps:

1. Ensure your transmitter is powered off.
2. Insert the bind plug (usually included with your transmitter or receiver) into the "BIND" port (Channel 3) on the FS-GR3E receiver.
3. Connect power to the receiver (e.g., via the ESC or a separate battery pack connected to the VCC port). The receiver's LED should start flashing rapidly, indicating it is in binding mode.
4. While holding the bind button on your transmitter (or following its specific binding procedure), power on the transmitter.
5. The receiver's LED should stop flashing and become solid, indicating a successful bind.
6. Turn off the receiver, then turn off the transmitter.
7. Remove the bind plug from the receiver.
8. Power on the transmitter first, then the receiver. Verify that the receiver's LED is solid and that the controls respond correctly.

Note: If binding fails, repeat the steps. Some transmitters may have slightly different binding procedures; refer to your transmitter's manual for specific instructions.

Operating

1. Failsafe Function

The FS-GR3E receiver features a failsafe function on Channel 2 (throttle) to prevent runaway models in case of signal loss. To set the failsafe position:

1. Ensure the receiver is bound to the transmitter and both are powered on.
2. Position the throttle stick on your transmitter to the desired failsafe position (e.g., neutral or brake).
3. Locate the small failsafe button on the receiver. Press and hold this button until the receiver's LED blinks once, then release.
4. The failsafe position is now set. To test, power on the transmitter and receiver, then turn off the transmitter. The throttle should move to the set failsafe position.

It is recommended to set the failsafe to a neutral or brake position for safety.

2. Channel Assignment

The FS-GR3E receiver has 3 channels. Standard assignments are:

• Channel 1: Steering (for RC cars/boats)
• Channel 2: Throttle (for RC cars/boats)
• Channel 3: Auxiliary function (e.g., lights, gear shift, or used as Bind port)

Maintenance

To ensure the longevity and optimal performance of your FS-GR3E receiver, follow these maintenance tips:

• Keep the receiver clean and free from dust, dirt, and debris. Use a soft, dry brush or compressed air for cleaning.
• Avoid exposing the receiver to water or excessive humidity. If it gets wet, disconnect power immediately and allow it to dry completely before re-use.
• Store the receiver in a cool, dry place when not in use.
• Regularly check the antenna wire for any cuts, kinks, or damage. A damaged antenna can significantly reduce range.
• Ensure all connections to the receiver are secure and free from corrosion.
