To power the already popular Ballistic 550 Brushless Motors, Novak is releasing the all new 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. On top of that, Novak is releasing a Havoc Pro SC/Ballistic 550 Short Course System – 4.5T (#3115) that is compatible with most 4WD short course trucks, including OFNA’s® Hyper 10 SC Pro 4x4 Kit™ and OFNA’s® Jammin’ SCRT 10 4X4 Kit™, and a system specifically designed for the Traxxas® customer. 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. Both 4.5-turn short course systems also include 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)
If you order the kit call Novak and order a board for the speed controller cuz 3 out of 3 that were delivered in my area from different shops were all bad. Just call novak and they send one no questions. Order and call the same day, that way you dont have to wait an extra week for your truck to be running. Once you get it its SICK!!! 1/4 throttle is more than full throttle with the traxxas vxl system. Night and day difference. Also look into a 50/100c 5000+ battery to power this thing. It sucks some power. My turnigy batts (5000 40/50c 2s) ran 18min on tight sc track before hitting lv cut off.(2.74v?just the batt I guess?) Thats with 12/54 gearing. Temp after 20 min was 155* motor and 120* sc. batt 100* 82* amb VERY HAPPY!

Novak Havoc Pro SC Brushless ESC/Ballistic 550 Motor Combo w/X-Drive (4.5T)
I have the Losi 4x4 truck and got this sytem because I have always been a Novak fan in the past. This system has not impressed me and has really let me down. I can almost always TQ the qauls but can not ever finish the mains due to Cant get any run time. I have tried three diff type batt the latest being 6000 60c batts. Cant ever make it past 8:30 before hit lipo shut off. Sent the system back to Novak, got the new one in hit the track, and SAME thing....time to pack it up and sell it for the Tekin.

Novak Havoc Pro SC Brushless ESC/Ballistic 550 Motor Combo w/X-Drive (4.5T)
Hello, I had the earlier version of this combo and updated it to this one. After carefully soldering the wires to motor tabs and tested the system everything looked good with the esc-leds. After calibrating the throtle range it was time to test the motor. Nothing happened and the motor was turning only after givin a small roation to the shaft first by finger. After installing the sparesensor the system started to work. On my first time at the track the motor did always power down in some situations at about five minutes run. Today we are going to inspect is the fault in motor of esc. I give only one star because the QC don´t seem to be on a level it should with this range of combos.
