Tekin: RSXpro ESC - 8.5 Gen4 Sensored BL Motor System
Tekin’s fourth generation brushless motors are engineered for award-winning performance. Utilizing the best materials available, we designed the GEN4 to cut weight while reducing resistance, resulting in a purebred racing machine. From Drag Racing to 4WD Modified Buggy, the GEN4 motors handle all situations, providing the smooth power and control across all RPMs when you need it. The GEN4 Modified motor is competition performance with the speed you need to win. Pair with an RSX Pro for the ultimate in modified racing equipment.
NEW DESIGN
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 Modified motor is a premium performance power plant for the serious racer.
