Product Description

GoolRC Flysky FGr4D Receiver, 2.4GHz 4CH AFHDS 3 Remote Control Receiver

The FGr4D is a four-channel two-way receiver based on AFHDS 3 protocol. This receiver features dual antennas, PPX6 nano waterproof, compact and lightweight design. It supports 4 Newport function interfaces. The FGr4D can be used as a PWM converter, adaptable to a model car or model boat

Built-in Dual Antennas

Wider signal, stable and full coverage.

FGr4D VS FGr4S

FGr4D receiver control the return communication distance to increase than FGr4S receiver.

PPX6 Nano Waterproof

Resistant to water jets from any direction and can be used with getting wet.

Durable Metal Pin Heade

Gold-plated pin header to improve corrosion resistance and extend service life.

Compatible and Application

2.4GHz 4 channel receiver is compatible with All Transmitters with AFHDS3 Protocol, such as flysky Noble NB4/Noble NB4 Pro/EL18/PL18/PL18 Lite/PL18 EV/PL18 EV Lite RC transmitter, suitable for remote control Car and remote control boat. Receiver Size: 30.3*25.8*20mm

Receiver Installation

The receiver has two built-in antennas. In order to ensure the signal quality and avoid the remote control distance affected, the receiver antenna should be perpendicular to the model body (as shown in the figure) when installing the receiver,

New Port Function: It supports new port function interfaces (New port canbe customized with input or output signal types: i-BUS2/ i-BUS/PWM/S-BUS//PPM).

Binding

The receiver supports two-way binding and one-way binding, and can be set at the transmitter side. The transmitter will display the information returned from the receiver after the two-way binding is completed.

Follow the steps below to bind in two-way binding:

1. Select Two WAY for RF standard of the transmitter, then put the transmitter in bind mode. 2. The receiver supports two ways to enter bind mode: BIND button binding and BIND button binding after power-on.

• BIND button binding: Press and hold the BIND button of the receiver while powering on the receiver, tthe LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button.

• BIND button binding after power-on: The receiver has not been connected to the transmitter when it is powered on. Press and hold the BIND button for 3 seconds, the LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button.

3. When the LED of the receiver is solid on, the binding process should be finished. The transmitter exits the bind mode automaticlly. 4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.

Follow the steps below to bind in one-way binding:

1. Select One WAY for RF standard of the transmitter, then put the transmitter in bind mode. 2. Put the receiver in bind mode ( Refer to the description above for entering bind mode). 3. After the receiver LED becomes slow flashing, then put the transmitter to exit the binding state. At this time, the receiver LED is solid on indicating the binding is successful. 4. Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.

Note: When this receiver is used as a PWM converter, it is necessary to finish configurations at the transmitter side. In this case, if the LED works in Flash-once, ON-once, and OFF-once state, it indicates that no i-BUS2 signal is received; if i-BUS2 signal is received, the LED works in Flash-once and ON-once stat.

Tried several times to bind it to my radio with no success.

From the beginning these worked fine, I saw no difference between the â€œSâ€ version in terms of performance, just the feature differences. Then I noticed the bind button wearing for no reason at all, but it didnâ€™t seem to affect anything. Eventually I needed to swap a receiver from one vehicle to another and the entire bottom of the case pulled apart from the top and broke. This happened a second time with the other â€œDâ€ version I bought after the receiver stopped working. I have 8 other S versions and they have all been flawless, including removal with the case staying intact. No more â€œDâ€ receivers for me until they put it in a better case.
