Product Information

• Product Name: FS-R4D-ESC Receiver

Introduction

The FS-R4D-ESC is a 2-in-1 receiver that is compatible with the ANT protocol. It features a compact design, an external single antenna, automatic binding, and a combination of the Electronic Speed Control (ESC) and LED light set control board. The receiver outputs PWM signals and car light control signals, supports two-way transmission, allows for ESC parameter configuration at the transmitter side, and can adapt to a variety of car models.

Receiver Overview
The receiver has multiple interfaces for different functions, including CH1, CH3, CH4 interfaces for control, car light interfaces for different lights, power switch cable, antenna, receiver LED, ESC LED, and CH interface signal pins. The car light interface is a standard 2.54mm*2 Pins.

Product Specification
The product has low/high voltage protection function. The ESC LED flashes slowly and continuously when the voltage is too high. ]When the temperature is normal, the channel resumes output.

The receiver automatically enters the binding state once it is powered on.

1. First put the transmitter into binding mode. (See the transmitter’s user manual for instructions on how to activate binding mode.)
2. Turn on the receiver, and it will wait for 1 second for connection. If without connection, the receiver will enter the binding mode automatically.
3. After the binding is successful, the receiver LED is solid on.
4. Verify that the transmitter and receiver are working properly. If you need to re-bind, repeat the above steps.

Notes

1. Set the transmitter to its binding state first, and then set the receiver to its binding state. If the binding is not finished within 10S, the LED of the receiver will enter its slow flashing state.
2.  If re-binding is successful, all the settings of the car lights will be restored to their default values.

Protection
This receiver has low/high voltage protection function.

• Low Voltage Protection : When the voltage is detected to be low, CH2 has no output and all the car lights flash slowly.
• High Voltage Protection : When the voltage is detected to be high, all channels will not output. All the car lights flash fast.
  • Note: The ESC LED flashes slowly and continuously; When the voltage is normal, then the receiver will exit the protection state.
• The ESC has overheating protection function.
• Overheating Protection : When the internal temperature of the ESC is detected to be too high, CH2 has no output and all the car lights flash fast. When the temperature is normal, the channel resumes output.

This receiver features 6 sets of lights: Left turn signal light(left light), right turn signal light(right light), headlight, tail light, ambient light and roof light. The car light control features four-channel control mode and two-channel control mode. Switching between the two control modes can be implemented by turning on the transmitter, turning the steering wheel clockwise to the maximum travel, and then turning on the receiver at the same time.

There are four modes/states of car light operation: Normal mode, sports mode, gradual mode and sharp flash mode. Quickly press CH4 button twice to switch the modes. By default, it works in normal mode. The state of all the car lights is controlled by the corresponding controls of the transmitter. Take FS-HW-G4P transmitter as an example, related description is as below.

The ambient light and roof light can work in separate or combination modes. You can turn the steering wheel from neutral position for four times clockwise quickly to switch the two modes. By default, it works in separate mode.
In separate mode, the ambient light and the roof light can operate independently without interfering with each other. In combination mode, the ambient light and the roof light can be controlled in a unified manner to work together.

The details are as follows

Troubleshooting

This receiver ESC function supports the settings of battery type, drag brake and running mode (forward/reverse, forward/reverse/brake) at the transmitter side. See the FS-MG11-BS transmitter manual for details.
After the motor is connected, the receiver automatically recognizes the throttle neutral every time it is powered on.

• When the connected battery type is lithium-ion, such as 2S LiPo, the ESC LED flashes twice (three times for 3S LiPo), and the motor fast beeps twice (3 beeps represent 3S LiPo) ; If the battery of ESC is NiMH cells, then the ESC LED flashes quickly once, and the motor fast beeps once.
• After the calibration is successful, the ESC LED flashes once and the motor will give a long beep. If throttle neutral is not recognized, the motor will continue to beep quickly. There is no power output from the motor at this time.

Notes

1. The ESC can be run after completing self-inspection (about 3 seconds) if power on, it may not be able to operate normally.
2. If there is no power output and the red ESC LED flashes quickly after power-on, it means that the throttle trigger of the transmitter is not at the neutral position, move the throttle trigger to the neutral position until the ESC LED does not flash.
3. If you find that the motor steering is not correct during operation, you can set the throttle channel in reverse at the transmitter side.
4. Normally, you must power on the transmitter and then receiver, and power off the receiver and then transmitter.
5. Refer to the relevant sections of the FS-HW-G4P, FS-MG41, FS-G7P or FS-MG7 user manuals for details about battery type, drag brake force and running mode of the ESC.

Description of LED status during normal operation

• The ESC LED is off when the throttle trigger is at the neutral position without any operation, and the motor has no output.
• The ESC LED quickly flashes when the vehicle moves forward, and is solid on when the trigger is at the end position of forward (100% or -100% throttle).
• The ESC LED quickly flashes when reversing or in failsafe state.

The failsafe function is used to output the channel value according to the out-of-control protection value set by the user after the receiver loses its signal and is out-of-control to protect the model and personnel.

• The failsafe setting on CH1, CH3 and CH4 of the receiver can be set at the transmitter side. “Not set” is the default setting.
• The CH2 (ESC), enters the braking state in case of out-of-control.
• If in emergency state, emergency lights keep last state in case of out-of-control. For other car light mode, all lights turn off in case of out-of-control.

Attention

• Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
• Please carefully check each power device and car frame instructions to ensure the power matching is reasonable before use. Avoid damaging power system due to incorrect matching.
• Do not let the external temperature of the system exceed 90℃ /194 ℉ , because high temperature will damage the power system.
• Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so can result out of control. Unreasonable setting of the Failsafe may cause accidents.
• After use, remember to disconnect the battery and the ESC. If the battery isn’t disconnected, the ESC will consume electric energy all the time even if it is off. It will discharge completely if connect the battery for a long time, thus resulting in the failure of the battery or the ESC. We are not responsible for any damage caused by this!
• Make sure the receiver is mounted away from motors or any device that emits excessive electrical noise.
• Keep the receiver’s antenna at least 1cm away from conductive materials such as carbon or metal.
• Do not power on the receiver during the setup process to prevent loss of control.
• If the throttle trim is changed on the transmitter side, the receiver needs to be re-powered to recognize the new throttle neutral. Otherwise, an exception may occur during vehicle reversing.
