The XR10 JUSTOCK ESC is specifically designed for zero-timing racing class. Its timing system has been permanently set to zero degree. Using the same branded motor and winding will ensure that every racer will have the same power system for 100% fair and competitive racing. Reliable hardware combined with advanced software technology allows the XR10 JUSTOCK to not only provide high power output, but also overload protection of the ESC circuit. The modified heatsink, which increases the surface area, combined with the Hobby Wing patented copper heat-conductive plates which are attached to the misfit board allows the internal heat to be quickly transferred to the heatsink for dissipation. With the high-performing detachable cooling fan, a highly reliable heat transfer system for maximum cooling is accomplished. With its compact design, the XR10 JUSTOCK fits most chassis from 1/10th touring cars, 1/12th pan cars as well as F1. Motor: the use of a heat-resistant magnet attached aluminum case and double insulated windings, Japanese high precision bearings, and rotor with a strong structure guarantees outstanding performance and Super durability. The aluminum case (different from the JUSTOCK3650 g1’s Iron case) with a unique design not only creates a cool look but helps to dissipate heat. The built-in Hall sensor Non-Adjustable end bell combined with a high precision and balanced rotor guarantees the user a smooth and linear power on demand. This motor is perfectly matched with the xr10-justock ESC for all zero timing Spec racing and also compatible with other Hobby Wing electronic speed controllers including other brands and is used in various 1/10th, 1/12th scale On-Road & off-road vehicles. It is an ideal choice for stock or sport class racing but can also be a great choice for beginners or for the racers looking for a practice motor.
