The Hobbywing XR10 Justock G3 ESC Combo with Justock G2.1 21.5T Motor (HW38020322) brings reliable, zero‑timing performance to spec racing. With fixed timing on the sensored Justock G2.1 21.5T motor and advanced control from the XR10 Justock G3 ESC, this matched system is engineered for consistent, fair competition.
Built on robust hardware and smart software, the XR10 Justock G3 delivers strong output with comprehensive protection. It supports an RPM speed limit function with up to six selectable limits to meet varied rule sets, and runs on 2S LiPo only. The ESC offers a linear BEC (6V/7.4V @4A), sensored or sensorless operation, built-in polarity protection and capacitor module, plus regular firmware updates via WiFi, OTA and LCD Program Box.
The Justock G2.1 motor features a heat-resistant magnet bonded to an aluminium case, double insulated windings, high precision bearings and a reinforced rotor for durability. A built-in hall sensor and non-adjustable end bell, together with a precisely balanced rotor, provide smooth, linear power. A silicon O-ring between the end bell and stator helps conduct heat to the case and resists dust ingress, while the case design supports easy cleaning and maintenance. The motor complies with IFMAR and ROAR specifications and pairs perfectly with the XR10 Justock ESC.
