Zero-timing Design

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.

Design

High Reliability & Durability

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.

Great Reliability & Durability

High efficient Heat
Dissipating System

The modified heatsink, which increases the
surface area, combined with the HOBBYWING
patented copper heat-conductive plates which
are attached to the MOSFET 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.

High efficient Heat
Dissipating System

Small Footprint

With its compact design, the XR10 JUSTOCK fits
most chassis from 1/10th touring cars, 1/12th pan
cars as well as F1.

Small Footprint

Wide Applicability

This ESC is designed for 1/10th scale touring cars & 1/12th scale pan cars as
well as the ever popular F1 series cars for all Zero-timing spec racing, example
the ROAR Sportsman class. When pairing this ESC with a 32T motor it will also
form a professional and ideal combo for rock crawlers.

Wide Applicability

Single-button Programming
& Factory Reset

The SET button on the ESC allows the user to easily program
or factory reset the ESC with ease.

Single-button Programming
