How do I bind the remote control to the vehicle?

Turn on the transmitter, then press the bind button on the receiver. The LED should change to solid green when bound.

What type of battery should I use?

Use a 7.2V NiMH or 11.1V LiPo battery with a T-plug connector. Ensure the battery is compatible with the ESC.

How long does the battery last?

Depending on driving style and battery capacity, runtime is typically 10-20 minutes. Allow the motor to cool before recharging.

Why does my car not move?

Check the battery charge, ensure the transmitter is turned on and bound, and inspect the ESC for error beeps. Refer to the manual for beep codes.

Can I use the car in wet conditions?

The WP-SC8 ESC is waterproof, but other electronics may not be. Avoid water puddles and clean the car after damp runs.

How do I adjust the steering trim?

Use the trim dial on the transmitter labeled 'ST TRIM' to adjust the neutral position of the steering servo.

What is the maximum speed?

Approximately 50 km/h with a 3S LiPo battery, depending on gearing and terrain.

The motor makes a strange noise. What should I do?

Check for debris in the drivetrain, ensure all gears are meshed properly, and inspect the motor bearings. Lubricate if necessary.

Can I upgrade the car?

Yes, Hobbywing offers various ESCs, motors, and other accessories. Many third-party parts also fit.

USER MANUAL 30850000 Hobbywing

Electronic Power Switch

Thank you for purchasing this HOBBYWING product! Devices used on RC models can be dangerous, any improper use may cause personal injury and damage to devices, so please make sure to read through this manual before use. In that we have no control over the use, installation and maintenance of this product or other related electronics, no liability may be assumed nor will be accepted for any damages, losses or costs resulting from the use of the product. Besides, we don't shoulder any responsibility for any losses caused by unauthorized modifications to our product. The last but not least, we have the right to change the product design, appearance, features and operating requirements without notice.

01 Introduction

This Electronic Power Switch features multiple functions like battery capacity indication, low-voltage indication, over-current protection, short-circuit protection and thermal protection; it can control the ON/OFF of current flow to the receiver, and it is operated by only one button, this helped to solve problems like bad contact caused by vibration or oxidation of contacts conventional mechanical switches have. As its case is made of plastic, it can be easily mounted at any place via the double-faced adhesive tape. Besides, the waterproof design makes it applicable for all weather conditions.

02 Begin to Use the Electronic Power Switch

Please connect the JR female connector (Input end) to the receiver battery and plug the JR male connector (Output end) into the Battery channel or any other unoccupied channel on the receiver according to the following diagram.

Specifications

Battery Type LiPo / LiFe / NiMH

Input Voltage 2S LiPo / 2S LiFe / 5S NiMH

Max. Current 12A

Size 26.5X19.7X10.5mm (LxWxH)

Weight 7.5g

03 Switching On/Off & Setting

1 Switching On/Off

Switching On:

Please press the power (/RED) button to turn on the electronic switch after connecting it to the battery; then both the POWER LED and the BATT TYPE LED will come solid on. (For detailed explanation about LED status, please check the two forms below)

Press the power button, then both LEDs will turn solid on.

Switching Off:

After turning on the electronic switch, press the power button again for about 0.5 second can turn off the switch and make both LEDs go out.

Press the button for about 0.5 second, both LEDs will turn off.

2 Setting (Battery Type)

It's important to set the battery type properly. If not, then the battery capacity indicator and low-voltage indicator will function abnormally. Therefore, when the first time you turn on this switch and find the color of the BATT TYPE LED doesn't match with the actual battery type, please set it again. And you also need to reset the battery type after changing another type of battery. The following part explains how to set the battery type: Keep pressing the POWER button after turning on the electronic switch, then the BATT TYPE LED will blink, about 3 seconds later the switch will enter the battery type selection mode and the LED will flash Green/Blue/Red circularly; release the button, then you can select the corresponding battery type to the color. (Please check the "BATT TYPE LED" form below for reference.)

04 Explanations for Different LED Status

BATT TYPE LED: Different LED color indicates different battery type.

BATT TYPE LED	Green	Blue	Red
Battery Type	LiPo	LiFe	NiMH

POWER LED: For battery capacity indication.

POWER LED	Solid Green	Solid Orange	Solid Red	Blinking Red
Remaining Capacity	80%~100%	60%~80%	30%~60%	0%~30%

05 Other Protections & Indications

Low-voltage Indication

When the battery voltage goes below the following threshold value for about 2 seconds, the POWER LED will blink RED slowly in this way "☆,☆,☆", but the electronic switch won't cut off its power output. Threshold Voltage of Different Batteries are listed below:

For a 2S LiPo: 6.0V;

For a 2S LiFe: 4.0V;

For a 5cells Ni-MH: 4.5V;

Thermal / Overheat Protection

1. Threshold "Temperature": 100°C (212°F);

2. When the internal temperature of the electronic switch goes above 100^ C ( 212^ F) for about 2 seconds, the POWER LED will flash RED in the following way "☆☆☆, ☆☆☆, ☆☆☆", but the switch will continue outputting power.

Over-current / Short-circuit Protection

1. Trigger condition of the over-current protection: The current is between 20\~39Amp and that lasts for about 500ms;

Trigger condition of the short-circuit protection: The current is over 40Amp and that lasts for about 500 s.

1. When the over-current/short-circuit protection is activated, the electronic switch will automatically CUT OFF the output and enter the protection; and the POWER LED will blink RED in this way "☆☆, ☆☆, ☆☆".

Battery Polarity Reversal Protection

(Note: It only works when no load is connected to the switch)

1. If it's not connected to any load, the electronic switch will trigger this protection to stop itself from starting up when detected the battery polarity at the input end is reversed.

2. If it's connected to some load and the battery polarity is wrong, the receiver and other connected devices will get damaged as they get the polarity-reversed voltage from the electronic power switch.

Either over-current protection or short-circuit protection can cause the receiver to lose power supply, so please ensure the current draw of all the devices connected to the receiver is below 12Amp (12 Amp is the maximum output current this switch can stand).

For avoiding possible damages caused by battery reversal, we strongly recommend disconnecting the JR male connector (Output end) from your receiver before connecting this electronic power switch to the battery; After connecting to the battery, try to turn on the electronic switch first; if you can turn it on normally, then you can plug the JR male connector (Output end) into the receiver.
