The Hobbywing Xerun XR8 Plus Brushless ESC/Motor Combo includes the awesome 4268SD G2 - 1900kV sensored motor to deliver unmatched power, performance and reliability for demanding 1/8 scale racing applications. Built with high quality components and loaded with cutting edge firmware, the XR8 Plus is responsive enough to protect itself from damage due to abuse, overuse, or even human error. With it's incredible power output and adjustable parameters, the XR8 Plus will deliver the smooth throttle response and linear throttle/brake qualities that discriminating drivers demand. Combine this incredible ESC with the Hobbywing 4268SD G2 Sensored Brushless Motor and you have an incredible combo package for 1/8 Off-Road Buggy applications.


  • ESC:
    • Built In High Voltage BEC: The XR8 Plus is the first 1/8 ESC that includes an integrated HV BEC with 15 Amp output current, and adjustable output voltage from 6 to 7.2V. This BEC is designed to handle power hungry servos with ease.
    • Reliable Cooling System: 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 utilizes a shock proof mounting system that reduces the possibility of fan damage due to the repeated shock of landing jumps in an 1/8 scale off road environment.
    • Coasting: The XR8 Plus provides exceptionally smooth off throttle coasting function (patent pending), which simulates the feeling of inertia and momentum of a large scale car driving experience. This greatly improves the performance of builds that utilize large high powered motors, as electromagnetic drag becomes a substantial factor in sudden deceleration when in the off throttle position, adversely affecting race performance and handling.
    • Advanced and Secure Electronic Switch: The XR8 Plus features an electronic switch that has been rated with a lifespan of over 50,000 on/off cycles. The switch is completely waterproof, dust proof and shock resistant.
    • Virtually Maintenance Free: Thanks to the well thought out design, the XR8 Plus is virtually maintenance free. Advanced error sensing and thermal protection, an exceptionally rugged housing, the ultimate in heat dissipation technology and shock proof fan mounting make this ESC able to withstand anything a racer can throw at it.
    • High Performance Dynamic Timing Algorithm: The XR8 is the worlds first competition level 1/8 scale ESC that has dynamic timing technology. This expands the adjustable power output range of the ESC while still maintaining system efficiency and smoothness.
    • Included Accessories: Includes 10awg wire, and mounting hardware. Does not include programming box.
  • Motor:
    • Full-Sensored Mode:The first motor (in the world) with a built-in chip which helps the ESC identify it's a Hobbywing motor (when pairing with XERUN XR8/XR8 Plus) and form a power system which can work in the "Full-Sensored" mode to provide users with improved performance and smoother control. Note: this motor is also applicable to other ESCs, but it cannot work in the Sensored mode at all times.
    • Turbo Timing Technology: When pairing this motor with HW XERUN XR8 series of ESCs, the Turbo Timing, which is widely adopted in 1/10th scale on-road racing, can be enabled and unleash the utmost power of the motor.
    • Bi-Directional Adjustable Timing: The bi-directional adjustable mechanical timing, can meet the different power demands of various applications. Bi-Direction refers to CW and CCW operation of the motor.
    • Advanced Hall Sensing System: The first "error-free" Hall sensing system adopted by this motor guarantees users the steady operation in the "Full-Sensored" mode. A separate high-speed high precision encoder always output the clean signals (indicate the rotor) and not be affected by other signal interference.
    • Low Cogging Torque: The first motor adopted the innovative 4-pole 8-magnet "staggered pole" rotor has extremely low cogging effect and low torque pulsation (it's reduced by 85% when comparing with traditional 1/8th scale motors).

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
I have run this exact combo in a buggy and it is great. It was not my buggy which made me all that more impressed.
Also, I read a review from an "Aussie" that he can not get support from a company in America. First, A-main has without a doubt the best customer service in the RC industry and second, Hobbywing is not an A-main product. Contact HW if you need answers.
I wonder how many American's buy from an Australia company and get quality service just to be fair?
Last, the phone number is at the top. Pay the fee and call them.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
Good combo. So much power and speed. Tested it on pavement with Schumacher mini pin tires. Getting some wheel spin and explosive speed off the line.

Fits in my tekno buggy no problen. Finding a place for the big on/off switch is the only difficulty in this thin buggy. Just mount it to the front side of the receiver box for tekno owners.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
Had overheating problems with this combo (motor would overheat and the ESC would go into thermal protection which means me shutting down in the middle of a race), so I slapped some fans on it which got me by, but then I found out the rotor was cracked after taking it apart to inspect. My drive train is smooth as butter and I went down to a 15T pinion, so it was NOT something I did wrong. Hobbywing was great about getting a brand new motor shipped out to me right away, but only a few months later and the rotor is cracked on the replacement too. This time I'm out of warranty and they want $80 for a new one that only comes with a 90 day warranty (instead of 180)... no thanks, going to try the Tekin 1900kV motor this time around. The XR8 Plus speed control has not given me any issues, and I like the on/off switch on the Hobbywing over the basic mechanical switch on the Tekin ESC which is one of the reasons I ended up going with this over the Tekin ESC.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
So far I have been really impressed with this combo. Plenty of power and the ESC has many options to enable or turn down to your liking. Still getting use to all the electric components as I come from a Nitro background, but all in all. I am very pleased thus far and no complaints.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
Initially bought one of these combo for my MBX8 Eco buggy and was pretty happy with its performance. Tuning was made easy with the optional Hobbywing Wifi module. Performance is great. Easy to install and basically no maintenance involved. Now we have 3 Eco buggies all running the Hobbywing XR8 Plus/1900kv combo.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
Very nice performance .. Has lots of power for E-buggy racing and easy to set up.

1. Includes an extra fan.
2. Its a workhorse.. and takes a beating. (as far as temps go)

1. This thing is massive .. very large footprint for an esc.
2. The on/off switch is also huge .. like why ? it is almost a joke. Trying to find a place for it to look good in your buggy is not easy when space is limited.

Hobbywing Xerun XR8 Plus Brushless ESC/G2 Motor Combo (1900kV)
Great car for straight line runs with stock gearing. If you like that sort of thing. Be careful and keep your eye on the motor temperature. Changed to larger spur and smaller pinion. Car still very fast and motor temperature good I give it 5 stars after a few adjustments. Hope everyone who has one has fun!!!!!!!!

These products have very little support / servicability if purchased here then shiped to Australia,the escs capacitors can easily be damadged ,and cannot be readily purchased for replacement ! Handle with kid gloves ! Couvered in the US ,but if youre an international customers forget it .if anythin goes wrong with it you may not be able to get it fixed localy ,ie through hobywing australia.having said that! A Main are the only people that have responded to my problem with the accidendamadged capacitors, and are trying to find the identifications and values of them ,and their availability !
If i can get replacement.easy, ime keen to try the 1900 combo ......update ,ok so AMAIN haven't bothered to follow up !sent me an email saying they (shane) would try to get the cap info for me and would get back to me the next day ! Then 4 days later another email indicating they dont know about the 1st e mail,? Ever since i cant access live chat ? Thanks for nothing amain .
