XERUN XR8-SCT 140A – ESC
XERUN XR8-SCT 140A – ESC
Full-sensored Mode Supported
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
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.
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 theperformance 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.
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.
