ESC Overview

The RS PRO Black Edition utilizes both hardware and software advances recently developed for our latest ESC lineup. With its industry-leading Dual Power Board design providing Ultra Low Resistance, you can be sure that your motor is getting all the power you can give it. Dual Power Boards double the amperage, giving you more power, smooth control and reliability you can count on. The RS PRO Black Edition is over-engineered for ultimate performance. The RS PRO Black Edition was specifically designed for 1S-2S Spec Classes and Drag Racing to take full advantage of the ULR circuit design. ULR FlexWire is included with every Black Edition ESC.

This ESC is not intended to be used with the 6.5T SPEC-R motor or modified track racing applications. For 1:10 scale 2WD/4WD Buggy, Stadium Truck and Modified Touring Car we recommend the RSX Modified ESC as these setups tend to run at higher temperatures. The billet housing and fan shroud on the RSX provide sufficient cooling.

Motor Overview

Tekin’s SPEC-R brushless motors are engineered for award-winning performance. Utilizing the best materials available we redesigned the SPEC-R to cut weight while reducing resistance, resulting in a purebred Spec racing machine. On Road or Off, the SPEC-R handles all situations, providing smooth power and control across all RPMs when you need it. The SPEC-R is competition performance with the speed you need to win. Pair with an RS PRO Black Edition for the ultimate in SPEC Racing Equipment.

The GEN4 motor line is a completely new ground-up design. We put in the design and test time so you can reduce your lap times. The new stator is precision stamped and pressed, increasing efficiency and reducing resistance. Our motors are hand-wound with high purity copper wire and machined from 6061-T6 aluminum. Completely tunable with optional rotors and re-buildable, the new GEN4 SPEC-R motor is a premium performance power plant for the serious racer.
