Hobbywing Combo XR8 Plus & XERUN-4274SD-2250KV-G3

XR8 Plus ESC

High Reliability & Durability

Built with the most rugged and high-quality components and coupled with cutting-edge firmware, the XR8 PLUS is able to deliver unmatched power and performance for even the most hardcore of racing applications, but is also responsive enough to protect itself from damage due to overloading due to physical abuse, overuse or even human error.

Great Flexibility & Versatility

With strong torque and excellent output, the XR8 PLUS can definitely cater for all the power hungry requirements that professional drivers need. The highly adjustable parameters of the ESC will allow drivers to enjoy smooth throttle response when the throttle/brake linearity is utmost required.

High Voltage Built-in BEC

The XR8 PLUS is the world’s first 1/8th ESC that integrates a HV built-in BEC with an output current of up to 15 Amp and a switchable output voltage of 6V-7.4V. The high voltage BEC is designed to handle today’s high voltage servos on demand used by 1/8th scale vehicles.

Ultra-Reliable Cooling System

HOBBYWING’s patented cooling technology utilizes proprietary heat-conductive copper bars to rapidly and
effectively transfer all internal heat from the MOSFET board to the integrated CNC machined billet aluminum heatsink housing. The cooling fan adopts a shockproof mounting which effectively reduces the possibility of fan damage due to vehicle’s frequent jumps.


The XR8 PLUS provides an exceptionally smooth off-throttle coasting function (patent pending), which simulates the feeling of inertia and momentum of a large-scale car driving experience. This can greatly improve the performance of builds utilizing large, high-powered motors as electromagnetic drag becomes a substantial factor in sudden deceleration when in the off-throttle position, adversely affecting driving performance and overall maneuvering.

Advanced and Secure Electronic Switch

The XR8 PLUS features an electronic switch with a lifespan of over 50000 on/off cycles, housed in a completely waterproof, dust-proof and shock-resistant design.

Virtually Maintenance Free Operation

Because of the exceptional thought and design put into the XR8 PLUS, users can expect a virtually maintenance free operating experience, due to advanced error sensing and thermal protection, an exceptionally rugged housing, the ultimate in heat-dissipation technology and a special shockproof fan mounting able to withstand anything that a racer can throw at it.

High Performance Dynamic Timing Algorithm

The world’s first 1/8th scale competition ESC which has adopted dynamic timing technology, which has had great successes in 1/10th scale touring car competitions for a long time now, will greatly expand the adjustable power output range of the ESC while still maintaining the overall system
efficiency and smoothness.


XERUN-4274SD-2250KV-G3 brushless motor

1/8thpower System of pure sensor mode
Built-in chip for being easily identified by ESC when pairing with Hobbywing XeRun XR8 sériés of ESC, the motor can work in the "Sensored" mode at ail times, providing better manipulating performance and délicate feel.

1/8th Power System & Turbo Timing Technology

When this motor pairing with Hobbywing XERUN XR8 séries of ESC can start Turbo Timing technology which succeeded in 1/10th On-Road contest. The motor can release maximum power instantly. The maximum speed can be promoted by 50%. Easily win your rival.

The mechanical turbo timing of motor can be accurately adjusted in both directions (CW/CCW)
The mechanical turbo timing can be adjusted between 20-40°. It is convenient for driver to calibrate accurately output power of motor and meet power requirements of various application.

The efficiency is improved greatly, effectively reduce the température rise.
Compared with XERUN 4268/4274 G2, the motor structure is greatly optimized, the efficiency is improved by 6% or so, which reduce the motor température rise effectively (Reduce heating)

Safe and reliable 1/8th motor Hall sensor System
The motor adopts the patent technology of "error-free" Hall sensor System, the independent high-speed and high-precision encoder always outputs pure rotor position signal, which effectively avoids the interférence of sensor signal and makes the motor work stably in sensor State.

Excellent dustproof performance
The Off-Road motor is IP5X. Its excellent dustproof performance can easy to overcome various Off-Road dusty track environment.

Light weight
The design of 4268 SD G3 is optimized which reduce the weight of motor. The weight of 1900KV/ 2200KV is 315g/285g respectively. And the weight of 4268 motor is 330g, 1900kv/ 2200kv is 20g / 45g lighter than peers. The light motor is convenient for the driver to adjust the balance performance of vehicle.

Low Cogging Torque
The motor has low cogging effect and small torque puise.
It is very smooth at low speed and has superb manipulating performance.

Advanced material in the industry and outstanding product design

  • It was made of a single piece of aluminum bar processed by CNC precisely. There isn't any gap or a screw on the surface of the body. There is a silicone dustproof seal ring surrounds the sensor base. The details show originality.
  • The front cover contains two pairs of M3 and two pairs of M4 screw holes, which are suitable for various mounting bases.
  • The outlet terminal uses widened U-shaped gold-plated curved copper bar, which has very low internai résistance and is easier to weld.
  • The R-class insulation material at 240 ° C, the spécial high-strength adhesive at 340 ° C, and international top brand bearing can easily cope with the fïerce contest.
  • Various spécifications and models, covering 1/8th various applications
