The EDGE 2S has a 35% smaller footprint
than the GTB 2 and is ideal for vehicles
with limited space for electronics.

With its compact and lightweight design, the EDGE is ideal for all 1/10th, 1/12th-scale applications, as well as 1/16 and 1/18-scale micro applications. With a footprint 35% smaller than the GTB 2, the EDGE is sure to fit in any vehicle--especially one with little room for electronics.

However, don’t let its small size fool you. This is a feature-packed ESC. In addition to utilizing the same software as Novak’s popular Sportsman class GTB 2 ESC, the EDGE also boasts a low profile heat sink and an easy, “Plug-and-Play” set-up (No soldering, just plug it in and start racing!).

  • Model #1850 is factory-wired with a genuine Traxxas® battery connector and gold-plated bullet-style motor connector
  • Model #1851 is factory-wired with a Tamiya®-style battery connector and gold-plated bullet-style motor connector

Novak’s new EDGE ESC contains the latest R/C technology on the market, yet remains remarkably easy to use. Novak’s One-Touch Set-Up™ circuitry allows quick and easy set-up to the transmitter. Utilizing the One-Touch button and five LEDs, the EDGE boasts 12 adjustable parameters for complete customization; allowing the ESC to grow with you while your skills improve and your racing demands increase.

As racing can often push the limits of the electronics, the EDGE is equipped with sophisticated Thermal Overload Protection to protect the ESC from overheating. Additionally, like the rest of Novak’s top-of-the-line ESCs, the EDGE features built-in temperature monitoring circuitry to determine the ESCs operating temperature with a quick tap of the One-Touch button. Complete with built-in Voltage Cut-Off circuitry for both LiPo and LiFe batteries, the EDGE has it all.

The EDGE ESC also features zero motor timing advance and meets ROAR Sportsman Class guidelines for fair and consistent performance on the track.


The Edge 2S is available on its own to use with your current sensored brushless motor, or as a system

paired with the Ballistic Spec Brushless Motor. There are four cost-saving systems available:

  • EDGE 2S / Ballistic 10.5T (Model #3335): Provides the fastest speeds. Ideal for Mild Sportsman Modified Racing, or fast bashers!
  • EDGE 2S / Ballistic 13.5T (Model #3336): Ideal for 13.5-turn spec class racing; great for those searching for a balance of power and runtime.
  • EDGE 2S / Ballistic 17.5T (Model #3337): Ideal for 17.5-turn spec class racing and new drivers looking for good power and extended runtimes.
  • EDGE 2S / Ballistic 25.5T (Model #3339): Both the ESC and Motor are approved for racing events that follow USVTA rules. Motor includes the blue ring. System is also ideal for beginners looking for slower speeds and the longest runtimes.
