The Hobbywing XERUN XR10 Pro Stock 1S is a brushless ESC purpose-built for serious 1/12 and 1/10 Stock 1S class racing. Reliable hardware combined with powerful software — including 5 common select-to-use profiles — delivers precise power management for competitive on-road racing. At 20% smaller than the standard XeRun XR10 Pro 1S and weighing just 23.5 g (without wires), it saves valuable space and weight for chassis balance tuning. Optional wireless programming and real-time data logging via the Hobbywing WiFi Express module round out the feature set.

• Special Design for Stock 1S Class Racing: Reliable hardware combined with powerful software (contains 5 common select-to-use profiles) provides an ideal power solution for 1/12th Stock 1S class racing.
• Super Internal BEC: The built-in boost BEC allows users to power various servos and receivers without connecting any extra battery.
• Adjustable Throttle & Brake PWM Frequencies: The independent and adjustable throttle and brake PWM frequencies guarantee precise and accurate throttle and brake control.
• Programming/Upgrading/Data Reading Wirelessly: With Hobbywing's optional WiFi Express module (HWA30503000 — not included) and an iPhone or Android phone with the HOBBYWING WiFi Link app installed, the user can remotely program parameters, upgrade firmware, and check relevant data without leaving the control stand.
• Built-in Electronic Switch: The internal electronic switch with a lifespan of over 50,000 on/off cycles eliminates issues such as stuck reed, rust contact points, and automatic shutdown that conventional mechanical switches often have.
• Data-logging Capability: Records the maximum ESC and motor temperatures, the maximum motor RPM, and more in real time — reviewable via an LCD program box or WiFi module after each run.

Notice: Brushless electric motors and ESCs have huge amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large or heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.
