Hobbywing Justock G2.1 17.5T Sensored Motor (Fixed Timing)

The Hobbywing Justock G2.1 17.5T Sensored Motor (HW30408011) delivers controlled, repeatable performance for stock and sport class racing. With fixed timing and easy-to-use solder joints, it offers a smooth, linear power band thanks to a built-in Hall sensor, a non-adjustable end bell and a high-precision balanced rotor. A heat-resistant magnet bonded to the aluminium case, double-insulated windings and high-precision bearings enhance durability over long race days.

Thermal management and reliability are further improved by a silicone O-ring seal between the end bell and stator, helping conduct internal heat to the case while shielding the Hall sensor from dust. The case design supports routine cleaning and maintenance to prolong service life and maintain efficiency. The Justock G2.1 is perfectly matched to the XR10-Justock ESC for zero-timing spec racing and complies with IFMAR and ROAR specifications.
