Novak's Extreme Sport Motor Systems
Novaks XBR/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.
Novaks XBR/EX Sport brushless systems are available in three motor winds:
- #3030 XBR Sport / EX8.5 Brushless System's motor is 8.5 turns and the fastest of the XBR/EX Systems.
- #3031 XBR Sport / EX10.5 Brushless System's motor is 10.5 turns and offers a great balance of speed and run time.
- #3032 XBR Sport / EX13.5 Brushless System's motor is 13.5 turns and ideal for beginners and those wanting maximum run time.
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 XBR Brushless/Brush Speed Control is also available individually (#1720).
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
Novaks 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 driveability, 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). To upgrade the EX motor to SS-Series performance, Novak upgrade kit #5923 is available. This kit includes a sintered rotor and oversized bearings, which are required for optimal racing. The EX's bonded rotor is not recommended for racing.
Each motor is factory hand-wound and is put through rigorous testing, including a final dyno test to ensure that each motor meets Novaks rigid specifications.
