The first 1/8 scale competition ESC which can work the full-sensored mode at all times (when pairing it with a HOBBYWING matching motor). Turbo timing technology is implemented by the XR8 SCT to unleash the maximum power of a HOBBYWING matching motor. 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.

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).

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.

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.

Can this esc take a 4000mah 3s 50c lipo?
Asked by Ben Weetman on 6th September 2018


  • Input Voltage: 2-4S Lipo/6-12 Cell NiMH

Answered by: Ben @ Wheelspin Models

What is the max C rating from a 3s lipo this esc can take
Asked by Ben Weetman on 12th September 2018

There is no "max C rating" for an ESC... It will draw what it needs from your battery (if the battery C rating is high enough to supply it).

The minimum C rating for your batteries will depend on a number of factors - such as motor, gearing and vehicle weight.. Suffice to say though - the higher (genuine) C rating the better..
