The Novak Hammer SCT 1/10 Scale Brushless ESC/NX4 Motor Combo delivers 100% pure, sensor-based control and precision driving to enthusiasts looking for an incredibly smooth-driving, affordable, power upgrade for their 2WD 10th scale off-road short-course truck, 4WD or 2WD off-road buggy, and even power-hungry on-road cars. 

Novak's Hammer ESC is compatible with 2S and 3S LiPo batteries, is pre-wired from the factory with gold-plated bullet connectors, and the battery wires are open ended and pre-tinned ready for the battery connector of your choice! The ESC is based on Novak’s proven 1/10th scale ESC design. Drivers new to the Novak platform will experience a much more connected feel to their vehicle with strong braking control. The Hammer is factory-defaulted to LiPo mode with reverse turned on. Drivers can customize the Hammer firmware to suit their driving style, including Throttle Curve, Brake Power and many other parameters. No clumsy or complicated programming device needed – the Hammer is fully programmable with a press of a button!

Fun in the Elements

Big power means lots of fun, and often fun in all conditions. Designed with a silicone-gasket sealed case, the Hammer is protected from just about anything you run it through. Its extreme resistance to water, dirt, and other debris gives users confidence while running through the occasional jaunt through the water.

Added Protection
Novak has been designing and building sensor-based controllers since 2002, longer than any other company in the industry. Circuitry protection has always been at core of the design. The Hammer firmware includes thermal overload protection, low-voltage protection, and motor lock-up protection for added reliability. Additionally, on-board diagnostics are standard in the firmware including a motor sensor checking test, error sensing, and on-board temperature diagnostics.

The Novak NX4 540 4-Pole Sensored Brushless Motor offers 100% pure, sensor-based control and precision driving to enthusiasts looking for an affordable, incredibly smooth-driving brushless motor for their 2WD 10th scale off-road short-course truck, 4WD or 2WD off-road buggy, and even power-hungry on-road cars. The NX4 540-size motor easily fits into any 1/10th scale vehicle. It boasts 3,900Kv of pure sensor-based power, and includes a large-diameter Neodymium rotor for that extra torque needed. It is factory wired with heavy-gauge silicone wire for easy installation, and includes replaceable power wires for drivers wanting more custom installs – a feature not common on similar motors in the market.

Pure Sensor-Based Design
Sensor based motor technology has been the mainstay of all competitive racers and teams. The speed control constantly knows exactly where the motor's rotor is, and can deliver extremely smooth and controlled response. The motor does exactly what you tell it, exactly when you tell it. You cannot be more connected to your throttle than you are with Novak's 100% pure, sensor-based motor firing.

4-Pole Vs 2-Pole  
What is the difference between a 4-pole and a 2-pole motor? More magnetic poles on the rotor, and more coils in the stator mean the motor is suited for hard acceleration and heavier loads. While the 2-pole motors, such as the Vulcan Spec, thrive in high-RPM ranges, 4-pole motors will be superior in the flat-out acceleration race and constant low-to-mid RPM pulls. 4-pole motors thrive in heavier rigs, and typically run better on smaller tracks with lots of short acceleration requirements.

Heavy-Duty and Ready to Race
The Novak NX4 motor’s heavy-duty design is built for the demands of SCT racing.
