Built for elite-level performance in stock class 1/10 racing, this Hobbywing combo pairs the XR10 Stock Spec G2 ESC with the V10 G4R 21.5T sensored motor to deliver precision, efficiency, and reliable speed. With a compact design and advanced features, this combo is perfect for racers who demand power and control without compromising on temperature management or durability.
Combo Overview:
Advanced Technology & Real-Time Monitoring
This setup supports Hobbywing’s OTA programming (sold separately), offering live data logging and performance feedback such as throttle response, voltage, current, temperature, and RPM. Data is viewable via HW Link for post-race analysis and fine-tuning. Built-in protections include low-voltage cutoff, thermal safeguards for both ESC and motor, fail-safe for signal loss, and reverse polarity protection. Firmware updates are possible using the LCD program box or OTA module.
