Novak’s Extreme Sport Motor Systems

3030_31_32_xbrexsystem_150p.jpg
Novak’s EX Sport Brushless Systems are budget-friendly, making them ideal for R/C enthusiasts to upgrade to brushless and experience incredible power and starting torque, minimal maintenance, and longer runtimes.

Novak’s EX-Series Sport brushless systems are available in three motor winds:

* EX8.5 Extreme Sport Brushless Motor: 8.5 turns; similar to a 15-17-turn mild-modified brush motor (#3430)
* EX10.5 Extreme Sport Brushless Motor: 10.5 turns; similar to a 19-turn brush motor (#3431)
* EX13.5 Extreme Sport Brushless Motor: 13.5 turns; similar to a 27-turn stock brush motor (#3432)


Each EX Sport Brushless Motor is available in a combo system factory-wired with Novak’s new XBR Sport Brushless ESC. Like all Novak brushless systems, the brushless speed control and brushless motor are factory wired and tested together, and are ready to “plug and play” straight out of the box.

The following three XBR Sport / EX Brushless Systems will be available:

* XBR Sport / EX8.5 Brushless System (#3030)
* XBR Sport / EX10.5 Brushless System (#3031)
* XBR Sport / EX13.5 Brushless System (#3032)

NOVAK’S XBR SPORT BRUSH/BRUSHLESS ESC
The XBR Sport is more than just a sport ESC, it’s extreme. It has the distinction of being the first Novak ESC to include two great features new to Novak products: Auto-Detect Brush Mode, which detects when a brushed motor is connected, and automatically switches the ESC to its Brush Profile; and Built-in Motor Rotation Selector, which allows the user to easily select the direction of the motor rotation.

The XBR also provides the most protection you can get at a sport-level price, including: Water-resistant case, Built-in Li-Po Cut-Off Circuitry, Locked Rotor Detection Circuitry, Thermal Overload Protection, and a Built-in power output for an optional accessory fan.

FOUR PROGRAMMABLE THROTTLE PROFILES
Another XBR feature that breaks the sport mold is its multiple throttle profiles with full programmability, all without the need for a computer laptop. Within each of its four throttle profiles, the XBR has 4 Adjustable Parameters: Minimum Brake, Drag Brake, Dead Band, and Minimum Drive; the brush mode also includes Drive and Brake Frequency adjustability for further throttle customization.

The XBR is equipped with four user-selectable throttle profiles, two of which have reverse:

* Standard Brushless Mode (with reverse)
* Sport Brushless Mode (no reverse)
* Marine Brushless Mode (25% reverse)
* Racing Brush Mode (GTX performance with no reverse)

SPORT BRUSHLESS MOTOR FEATURES
Novak’s EX Sport motors also break the sport mold by including great features found on all Novak brushless motors like a convenient Solder Tab System for easy wire replacement; Sensor-Based Technology for excellent starting torque, low-speed drivability, and smooth acceleration; Thermal Overload Protection (when used with a Novak brushless ESC) that allows pack after pack to be run without fear of damaging the motor, battery, or ESC; and approximately 20% longer runtimes compared to brushed motors. Plus, the EX motors provide users the ability to upgrade or replace various parts like the front end bell/bearing and rear bearing (#5905) or rotor (#5906). The EX motors also provide users the option to upgrade the motor with a motor upgrade kit (#5923) to obtain the pro performance of the SS-Series of motors.

All Novak brushless motors are designed and manufactured in the USA. Each motor is factory hand-wound and is put through rigorous testing, including a final dyno test to ensure that each motor meets Novak’s rigid specifications.
