Full-Sensored Mode Supported

The Hobbywing XR8 SCT is the first 1/8 scale competition ESC which can work the full-sensored mode at all times when paired with a Hobbywing matching motor. Perfect for 1/10 4WD Short Course Truck, Monster Trucks and of course 1/8th scale, the XR8 SCT ESC boasts full sensored operation, 140A output, electronic switch, 6V/7.4V switchable BEC and wireless programming capabilities.  

In-Depth Features: 

  • Turbo Timing Technology: Turbo timing technology is implemented by the XR8 SCT to unleash the maximum power of a HOBBYWING matching motor.
  • Small & Light Structure Design: Small (30.1% smaller than XR8 Plus in size) and light (36.5g lighter than XR8 Plus in weight) structure design greatly simplifies the installation of the power system (esp. for vehicles like buggy and touring car with compact chassis).
  • Programming / Upgrading / Data reading wirelessly: With Hobbywing's "WiFi Express" module and iPhone or an Android phone (with the HOBBYWING WiFi Link software installed), the user can remotely program parameters, upgrade firmware and check relevant data of the ESC without leaving the control stand.
    *WiFi Module not included and sold separately: part# HWA30503000
  • Coasting: The XR8 SCT provides an exceptionally smooth off-throttle coasting function, 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.
  • Capacitor Thermal Protection: Capacitor thermal protection implemented by the XR8 SCT will effectively prevent capacitors from exploding and causing irreversible damage to the ESC due to overload.
  • High Voltage Built-in BEC: High voltage built-in BEC with an output current of up to 15 Amp and a switchable output voltage of 6V-7.4V allows users to use various high torque and high voltage servos.
  • High Reliability & Durability: Built with the most rugged and high-quality components and coupled with cutting-edge firmware, the XR8 SCT 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.
  • Advanced and Secure Electronic Switch: Electronic switch with a lifespan of over 50000 on/off cycles, housed in a completely waterproof, dust-proof and shock-resistant design.
  • 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.
  • Wide applicability: This XR8 SCT ESC is not only applicable to 1/8th buggies and short-course trucks but also 1/10th short-course trucks, trucks and monster trucks.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Awesome little ESC that packs a punch. I use it in an Xray XB8 2017 with the G2 4268 1900kv and 16T pinion. It's a rocket, especially with the turbo timing. Heat is no problem at all

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Excellent speed control! Easy to program, especially with the Wi-Fi Express module. Smooth, reliable and very powerful. It is a robust design that looks like it can take some real abuse. I wanted to wait a little while before posting a review to see how it handled a few races, and it has performed flawlessly. Admittedly, I am using not uing this for it's intended primary application/class. Despite that it is working really well, and I have no want or desire for anything more. Purchase with confidence!

As a side note the aforementioned Wi-Fi Express is a gem! It connects easily, and the Hobbywing iPhone application works very well. If you have the money, then it's a must have.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Esc works great running in a tekno 410.3 on 2s with a 4 pole 4300kv hobby star pro4 motor, ran for the first time at a club race plenty of power and smooth control in all 3 qualifiers however in the 8 minute main the esc went into thermal protect and i noticed the fan was not working, upon further inspection found not only had one of the blades broken off but the fan itself had also stopped working completely.I tested the fan to make sure it was the fan and not the esc causing it not to spin so i plugged the backup fan in and it works fine. Spare fan included in my esc package was wondering if this is a common problem .

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Awesome ESC! Nicely built, easy to program, very smooth. I paired it with the 1900 Hobbywing G2 motor in my Tekno EB48.4, and it's easily the fastest and smoothest combo I've run. Great value for the $$$$$.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
I have compared this esc to my tekin gx2 esc and I notice this hobbywing is more smoother, powerful over tekin. I ran it with two identical cars with the same batteries and hobbywing performs a lot better and the power switch is great, compared to tekin. That switch is like a 99cent switch that keeps failing all the time when I had it. Plus a huge price difference. Almost 100 dollar saving.

Bang for buck best esc you can buy. Run one in my 22sct and eb48.2. Not a hiccup with either. Didn't buy from amain but from my lhs but still have to tell people buy this esc you will not be disappointed.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Extremely happy with this ESC. Using it with a Tekin 1900kv in my Mugen and it's the smoothest electric combo I've had in 1/8 bar none. No brown out issues some complain about using savox high torque steering servo so the BEC is strong enough as well. No heat issues at all, no cogging, and the LCD box makes it ridiculously easy to program for your track. Would recommend to anyone.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Bought this from my local HobbyTown USA in Gladstone, MO and i have to say this is a great esc. I have used a couple Hobbywing esc's and i have a pretty good idea on what i look for in one. This thing is first off great looking and programs easy with the WIFI module. The ESC is definetly 8th scale size so if your using it in a smaller area you might want to make sure you can use it. The push button is great quality and lights up so you know its on. ESC programmed out of the box is a little light on the punch so you might have to turn it up. I am using it in a SC5M With Reedy M3 7.5 with 10 gauge wire and this thing runs really cool, and my motor doesn't even break a sweat with it. Only thing i am having a small issue with is trying to check my slipper setting the motor stutters. I have had Hobbywing Techs look into it but nothing really came up. Other then that performs like a champ!

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
I have this in my MBX7 Eco with a Surpass Taurus 1950kV 4274 motor and it's fantastic. The ESC barely gets warm during use and if anything there is too much power. I've had to turn down the punch to make it a bit more manageable.

The build quality is great and I like the accessories it comes with. All the wires you'll need with some heatshrink for the battery connection. It also comes with a bunch of stickers and a spare fan which is a great touch. The terminals are easy to solder to and so far I'm very impressed with this ESC. I have the BEC set to 7.2V and it never says under load from the steering servo.

I raced with it for the first time yesterday and it performed great. I had some tires come unglued but that's not the ESCs fault. :)

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
I rate this 10 stars! This is the best esc for 4WD sct!!! (IMO) Also great for 1/8 ebuggy. Pair it up with the WiFi express module for the easiest programming ever.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Got this and the Wifi adapter for tuning with my iphone. This speedo is butter smooth in my RC8B3.1e. I have it paired with a Motiv MC8 1950kv, 15-46 gearing 10 timing. I run punch mode 3 and 50% brake strength and the thing RIPS! Never worried about over-heating and throttle is awesome for the jumps. Very pleased and for the price I am very pleased. This is the speedo several of the pros use for ebuggy due to its 1 oz lighter than the XR8 Pro.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Very versatile, smooth, reliable power. I’ve used this esc in my t-4.3, my prosc10 and my axial wraith. Made my 10th scale stuff so fast I could barely run them on 3s. But I will say that for crawling this thing is a beast. The bec runs the savox 1210sg with ease and paired with the hobbywing 3800kv motor my little crawler scoots along pretty quickly. Programming is a breeze, and the programmable items available are all very functional and useful. I’ve been running this over a year now and have had no issues to speak of. Buy with confidence, this is a good product.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Fantastic ESC. I pair mine with the Tekin G2 motors. As the Viper VTX's get harder and harder to find, this has become my go-to. I like the small footprint, strong BEC, and find it to be smooth as silk. I now own 2 of them and don't see me trying another brand anytime soon. Hobbywing has created a really great lineup.

Running this in my MBX7R ECO with a hacker 2100kV on 4s. Beautifully smooth, runs cool, worth the upgrade if you are running the previous SCT PRO ESC.

Hobbywing Xerun XR8 SCT 1/8 Sensored Brushless ESC
Ran it on 2 battery packs and it broke. Unable to return, do to Hobbywings policy. Honestly buy something else and save yourself the headache. I give it a piece of junk and 2 thumbs down. Was installed on an Srx8 and set up correctly I know what I'm doing. I hardly ever give anything a 1 star but I wish i could give it a zero.

Being that of Army Veteran, I choose the FedEx store for delivery of package for security and insurance of delivery as at a Hotel their could be an issue of that! As I notified the FedEx Store the next Sunday after its delivery, they have continued their statement that USPS mail is not deliverable there and now my paid ESC is now missing! Hopefully they will found it and ship it back, as I have no clue or idea where it is. USPS customer is garbage and they only offered sarcasm! It will not happen again!
