WHITESIGNAL WIRES: AUX3 CH Function 1

[AUX4 and AUX4 CH Function] YELLOWSIGNAL WIRES: AUX4 CH Function 2

Built-InUltra-High-Voltage BEC

Output voltage supports 6-14V

Supports fine adjustment in precise 0.1V increments

Maximum output current is up to 35A

The industry-leading BEC provides ample power for standard, high-voltage and ultra-high-voltage servos, as well as accessories such as lighting systems and winches.

Important: Most receivers are rated for a maximum input voltage of 9V or less. Before setting the BEC output above 8.4V, always confirm that your receiver supports the selected voltage. Excessive voltage may damage the receiver.

FOC Sensored Technology forSmooth Powerful andNearly Silent Performance

FOC technology delivers exceptional low-speed torque for demanding crawling applications. Even at extremely low speeds, power delivery remains smooth and precise, while operating noise is significantly reduced compared with conventional drive systems. The result is greater control and a quieter, more immersive crawling experience.

Intelligent Torque Control

When the car is going uphill: The ESC automatically increases torque to overcome resistance and maintain momentum.

When descending: It reduces torque and regulates the vehicle’s speed for greater stability and control.

Smart Cooling,Quieter Operation

The cooling fan remains off at low ESC temperatures and automatically switches on when the preset temperature is reached. This intelligent system reduces noise and power consumption while maintaining an optimal operating temperature.

Note: The automatic fan function can be disabled.

IP67-Rated Protection

The ESC is IP67 rated for excellent water and dust resistance, delivering reliable performance across demanding outdoor environments, varied terrain and changing weather conditions.

Note: Under normal operating conditions, the IP67 rating provides protection against splashes, temporary water exposure and dust. Protection may diminish over time due to wear and ageing. Prolonged submersion may damage the product and should be avoided.

Built-In Bluetooth withDirect App Connectivity

The ESC features built-in Bluetooth, allowing it to connect directly to the HW Link app without any additional devices. Adjust settings, view operating data and update the firmware quickly and conveniently from your smartphone.

Real-Time PerformanceMonitoring

Connect the ESC to the HW Link app to view key operating data in real time, including throttle input, voltage, current, temperature and motor speed, giving you a clear overview of the power system’s status at a glance.

Note: The effective Bluetooth range is approximately 5 metres.

Four Versatile Driving Modes

Choose from four driving modes to suit a wide range of applications:

Forward/Reverse

Forward/Reverse with Brake

Hybrid Mode

Forward with Brake

Supports Real-time Telemetryand ESC Tuning with Flysky NB4Series Remote Control

It supports the FlySky NB4 series remote control, enabling real-time monitoring of key data such as battery voltage, motor RPM, operating current, and ESC/motor temperatures. It also allows for real-time adjustment of ESC parameters directly from the remote control making tuning more intuitive and convenient.

Note: This feature requires a firmware update for the FlySky remote control. The actual support date is subject to the FlySky firmware release schedule.

Extensive Tuning Options

With 22 adjustable parameters and up to 24° of Turbo timing, the ESC can be precisely configured for different vehicles, terrain and driving preferences. When conditions allow, Turbo timing unleashes maximum motor speed at full throttle.

Motor Info.

High-Power Motor for Large Scale Crawler
Designed specifically for 1/5 and 1/6 crawlers, the XeRun AXE 4987 R3S delivers unparalleled torque, ultra smooth low speed control, and amazing drivability. Zero cogging and powerful response allow even the most demanding large scale builds to tackle the toughest terrain.
 
More Power in the Perfect Size
Sized at 49mm diameter and 87mm can length, the AXE 4987 fits into tighter builds and still provides more power and torque than motors in this segment. Improved acceleration, more efficiency all adds up to better overall performance.

Perfectly Matched with the XeRun AXE Plus R3 ESC
When paired with the XeRun AXE Plus R3 ESC, the AXE 4987 R3S motor delivers incredibly smooth low-speed operation and tremendous low-end torque, providing a level of control and driving feel that far exceeds conventional sensored power system.

Ready to take on Any Trail Condition
Rated at IP66, you can rest assured that your rig will survive even the messiest of trails. Rain, Snow, Mud, Sand or water, the AXE R3S will take it.
