We’re thrilled to introduce the Cobra 8, our next generation electronic speed controller (ESC) for surface applications. As the inaugural product in a new line, the Cobra 8 is engineered with cutting-edge technology tailored specifically for 1:8th scale vehicles.

The Cobra 8 boasts a state-of-the-art 32-bit dual-core processor, ushering in a new era of precision and performance. Its enhanced data logging capabilities offer extended recording times, faster sampling rates, and a wealth of data points, enabling users to delve deeper into their vehicle’s performance than ever before.

Crafted with a CNC aluminum bottom case, the Cobra 8 is engineered to endure the most rigorous conditions, ensuring reliability in every race or off-road adventure.

One of its defining features is our acclaimed CRYO-DRIVE™ technology, engineered to reduce operational temperatures, significantly prolonging the ESC’s lifespan. Moreover, equipped with an impressive 8-amp BEC, the Cobra 8 can effortlessly power the most demanding servos, making it an indispensable ally in your high-performance setup.

We’ve packaged the Cobra 8 with three different Castle 4 -POLE 12-SLOT motor options to overpower a wide range of 1:8th scale vehicles.
