Size does matter, and sometimes smaller really is better. A common problem with some of today’s vehicles is that they have very little room for electronics. Enter the Impact Racing ESC, Novak’s Super-Tuner, X-Drive-equipped, pint-size power house.

The Impact has been paired with Novak’s top-of-the-line Vulcan Spec 17.5T motor to offer spec racers the ultimate combo for today’s tight-on-space vehicles. The Vulcan Spec 17.5T uses Novak’s new Red-Wire, high-RPM, hand-wound stator and a 12.5"m tuning rotor for “THE” motor to have in the spec-racing world. Novak's Impact is small in size and huge in tuning features. This modified-rated ESC has the proven Novak go-fast features of its bigger brother the Pulse, but sized down to fit a wider range of vehicles that never require hot mod motors.
