Novak Activ8 Racing Brushless ESC

This new brushless ESC from Novak is designed for 1/8 electric vehicles and is packed with features like a full-coverage heat sink, 12 gauge power wires, high-powered switching BEC, and Novak’s patented X-Drive software. Read the info below for more details:

Novak Electronics is proud to introduce a new definition in power, performance, and reliability with the new Activ8 Racing Brushless ESC (#1725). This pure, sensor-based brushless racing ESC is designed for the rigors of electric 1/8th scale buggy/truggy, but can also be used in 4WD short course trucks. The Activ8 features Novak’s X-Drive™ for ultimate driving performance, on-board programming for complete customization, and is built and supported by Novak Electronics in Irvine, California. The Activ8 has no shortage of features and is ready for any power-hungry 2S to 4S application. If you need an ESC that is beastly enough for your maniac driving style and heavy throttle finger, the Activ8 is what you have been waiting for!


Your vehicle isn’t wimpy, so why put a wimpy controller in it? The Activ8 uses high quality and rugged components to ensure your vehicle keeps running pack after pack.

Full-Coverage Heat Sink

For proper heat dissipation, the Activ8 takes full advantage of its robust size and features a full-size, cross-cut heat sink that has direct contact with all of the power MOSFETs. Whether you are ripping through the high desert or tearing off laps at your local arena, the heat sink is the first line of defense against heat build-up. A large cooling fan and fan guard are also included.

Heavy Duty High-Power PCB

The Activ8 uses an extremely heavy-duty and thick PC board that is embedded with massive, pure copper traces to ensure your ESC performs at its best.

Huge Power Wires

The Activ8 comes factory-installed with 12 gauge silicone battery and motor power wires that are easy to replace for factory-like, re-wire jobs. These power wires don’t just have a “12” printed on them- they are top-quality, Novak Super-Flex wires.

High-Powered Switching BEC

To cope with the demands of heavy-duty servos and the rigors of extended practice sessions with heavy vehicles, the Activ8 features Novak’s new high-powered switching BEC, which utilizes rugged components, for a clean and consistent 6 volts output.


Novak X-Drive™ will provide incredibly smooth throttle response while maintaining an extremely connected and controlled feel. This motor-firing technology has been taking the racing world by storm and is now available for the larger scale, higher voltage applications. No competition ESC is complete without X-Drive!


To deliver unmatched performance and usability in the high-end, high-voltage ESC category, Novak engineers developed enhanced, on-board programming to ensure that customizing and tuning the Activ8 to your liking has never been easier. Gone are the days of special boxes, programmers, or lugging your expensive laptop to the dusty track. Nothing extra is needed, and making changes track-side is a snap!

Drag Brake: Allows tuning of the auto brake, drag brake or coast brake response Dynamic Timing: To disable, activate, and adjust the amount of Dynamic Timing Advance™ that is applied to motor
RPM Set Range: Allows control when and how the Dynamic Timing engages with regard to the motor’s actual RPM
Drive Frequency: The throttle response or sensitivity allows fine-tuning of the motor’s snap or feel
Brake Frequency: The brake response or sensitivity, allows fine-tuning of the motor’s brake feel
Minimum Drive: The lowest RPM the motor can start, which allows adjustment of the “punch”
Minimum Brake: Initial brake tuning allows adjustability to how quickly or hard your brakes bite at first application
Deadband: The space between the brake and throttle allows you to adjust your basic throttle sensitivity


Low-Voltage Protection

A new low-voltage LiPo protection segment has been developed and will monitor the LiPo pack voltage thousands of times per second. In order to prevent the pack from ever falling below the critical safety voltage, the ESC will simply reduce the power, slowing down the vehicle.

Thermal Protection

The ESC keeps tabs on its core operating temperature and will back down its power to prevent the ESC from overheating. ? On-Board Temperature Diagnostics – With a quick tap of the One-Touch button, multi-colored LEDs will indicate how hot the ESC is for instant temperature information.

Error Sensing

Sampling has been expanded to provide additional feedback via multi-colored LEDs, allowing for quicker trouble-shooting.

Motor Lock-Up Protection

If your drive train or motor becomes bound up or jammed, the ESC will detect this and cut the power to prevent damage.

Hall Effect Sensor Test

This built-in test allows you to confirm that your motor’s sensors and sensor harness are in good working order.


The Activ8 Racing Brushless ESC was primarily designed for use with Novak’s Ballistic 8 Racing Brushless Motors, but is also compatible with Novak’s Ballistic 550 Racing Brushless Motors, and all popular 1/8th-scale (15XX-size), 550-size, and 540-size, 2 or 4-pole, sensored brushless motors.


Novak takes pride in its manufacturing facility in Irvine, California and also with its use of high-quality components and assembly and testing processes. Each Novak Club ESC and Brushless Motor is built and tested in the Novak factory to Novak’s exacting standards.
