The Hobbywing XERUN V10 Rotor Φ5-12.5-U-T, model number 30820013, is aimed at racers who want a robust yet lightweight rotor that improves throttle control and torque feel. The titanium-alloy shaft maintains strength while trimming rotating weight, which helps reduce lag and stabilise the motor at race speeds. It is a practical upgrade for on-road setups targeting quicker spool-up and consistent power delivery.
