Hobbywing Std Capacitors Module B (XR10 Stock Spec G2)

The Hobbywing Standard Capacitors Module B (HW30840008) is the factory-recommended capacitor bank specifically tailored for the XeRun XR10 Stock Spec G2 and other compact 1/10 scale ESCs. Because "Stock Class" racing focuses on extracting every ounce of efficiency from spec motors (like 17.5T or 21.5T), Module B is designed to be ultra-compact and lightweight while still providing the essential voltage stabilization needed to prevent performance "fade" during a 5-minute main.

Key Features:

• Ultra-Compact Profile: Smaller than Module C or D, this module is designed to fit into the extremely tight electronics trays found in 1/10 2WD buggies and pan cars.
• Optimized for Stock Racing: Tuned for the specific switching frequencies of Stock-spec ESCs, ensuring that the motor receives a clean DC signal for maximum efficiency and minimum heat.
• High Ripple Current Protection: Protects the ESC's internal MOSFETs from the back-EMF spikes generated during hard braking and rapid direction changes.
• Lightweight Design: Every gram counts in Stock racing; Module B provides the necessary filtering without adding unnecessary bulk to your chassis.
• Low Impedance: Utilizes low-resistance electrolytic capacitors to ensure rapid discharge and recharge cycles, keeping up with high-frequency throttle inputs.

Application Tip:

While Module B is the standard for Stock Spec racing, if you are running in the Modified class or using a very high-torque servo, you might experience more "ripple" than this module can fully suppress. In those cases, you can upgrade to Module C for more capacity. However, for most 17.5T and 21.5T applications, Module B is the perfect balance of size, weight, and performance.

Note: Ensure the wires are soldered as close to the ESC battery input as possible. Long wires between the capacitor and the ESC act as an inductor, which can significantly reduce the capacitor's ability to filter out high-frequency noise.
