To power the already popular Ballistic 550 Brushless Motors, Novak is releasing the Havoc Pro SC Brushless ESC (#1745). It’s the first speed control specifically designed to meet the rigors of short course racing. In fact, it includes everything any short course enthusiast could ever want in a speed control: It boasts electronic timing, on-board programming with 14 adjustable parameters, a brand new braking system, and it comes factory wired to the most powerful short course motor available. Stop your search here; Novak has the short course system for you!

The versatile speed control is also compatible with 540 and 550-sized brushless motors to easily power 2WD and 4WD short course trucks. The Havoc Pro SC/Ballistic 550 Short Course System – 4.5T TRA (#3116) includes a custom install plate and a high-current handling Traxxas®-compatible battery connector to fit easily into Traxxas’® Slash 4X4 4WD Short Course Trucks™ without soldering, as well as a free rugged 5mm pinion gear to promote plug ’n’ play action.


  • What is Novak’s X-Drive? This new update significantly improves the throttle feel and response. It also reduces the ESC’s operating temperatures for more efficient operation. Team drivers, test drivers, and customers who have run the Havoc Pro SC with X-Drive in side-by-side comparisons to their original ESC have all noticed an incredibly smooth feel, improved drivability, lower temperatures, and overall higher performance resulting in faster lap times and longer run times.
  • How Does Novak’s X-Drive Work? Simple. The switching speeds of the ESC’s transistors have been drastically increased. Speeds of this nature have not been considered until now. Novak engineers have developed this exclusive firmware and hardware update that permit the Havoc Pro SC to have the absolute best response times and switching speeds.

SPECIFICALLY DESIGNED FOR SHORT COURSE: Novak has piled on numerous new features to completely reinvent the Havoc Pro SC. From its smaller case and new cross-cut heat sink to its completely redesigned software, you won’t even recognize it! Among the Havoc Pro SC’s many new features is its Dynamic Timing Advance™. This electronic motor-timing feature has eight adjustable timing settings and increases the motor RPM dynamically throughout the throttle band. The additional RPM, in turn, results in higher speeds and improved speed control performance. Moreover, Novak added a timing indicator LED, which will illuminate white whenever timing is activated. This feature will help aid club racing events that run timing and non-timing events.

To combat overheating while timing advance is activated, Novak has upgraded its Thermal Overload Protection™ feature. If the ESC starts to overheat, the speed control will turn off the timing advance. If the ESC’s temperature continues to rise, a second thermal-protection feature will engage. This feature drops the speed control’s power to 25 percent, so drivers can safely maneuver their vehicle off of the track. This refined protection feature is exclusive to Novak’s newest sensored speed controls, like the Havoc Pro SC. On top of that, Novak is introducing a new temperature indicator that alerts racers of their ESC’s temperature after each run. This indicator is so accurate that many racers use it in place of a temperature gun. A quick tap on the One Touch™ button at the end of a run will display the speed control’s temperature via a blinking LED.

Another feature that originated with Novak’s design team is the patent-pending NovaBrakes™. This revolutionary braking system provides instantaneous braking under any timing condition. Additionally, the brake response is incredibly smooth and immediate at any speed or throttle position, ridding the ESC of brake delay. In short, this new braking system has completely transformed the feel, response and use of traditional brakes. Combined with the NovaBrakes, Novak has refined the Havoc Pro SC’s brake and drive frequency settings, and added a brake end point adjustment to provide drivers with unparalleled brake and throttle tuning options. The brake and drive frequency settings allow users to experiment with a softer or heartier brake and throttle input. Additionally, Novak has equipped the Havoc Pro SC with a Hall Sensor Test™. When activated, this test quickly verifies if the sensor harness and sensor in the motor are functioning properly without any risk to the ESC or motor. This Hall Sensor Test is an invaluable tool when troubleshooting at the race track.

Novak’s new 550-sized motors are a powerful complement to the sophisticated Havoc Pro SC. The Ballistic 550s are so dominant because of their extra long stator and rotor magnet. In fact, the stator and rotor magnet are twice the length of 540-sized motors, giving them twice the torque of an equivalent 540 motor. Additionally, these larger-sized motors run cooler and more efficiently than their 540 counterparts. And like the Ballistic name implies, these motors are completely rebuildable and feature interchangeable wound stator construction.

Novak Havoc Pro SC Brushless ESC/Ballistic 550 Motor Combo w/X-Drive (4.5T) (Traxxas)
I have raced this in my slash 4x4 two times now, and it is as fast as any other truck and system on the track, runs very cool. I geared up one tooth from what is included and could still be geared taller with no problem. So far very happy with the performance of this combo, just need to turn the brakes waayyyy down, as at the end of a long straight if I am not carefull will do a stoppie(no exageration) The brakes are so strong that even if the air gets caught under the body and brings the nose up, it will still bring the nose back down with the brakes. Kenddall recommende this combo and was right on!
