The newest addition to Novaks brushless motor family is the EX Sport Brushless Motor Series. The budget-friendly sensored brushless motor series is ideal for R/C enthusiasts who have always wanted to join the brushless revolution, but have resisted.

With Novaks EX-Series brushless motors, the time has come to painlessly make the step up to brushless and personally experience all of the things said about brushless, but just found hard to believe; things like: incredible power and starting torque, minimal maintenance, and longer runtimes.

SPORT BRUSHLESS MOTOR FEATURES
Novaks newest motors also sport a new look for a Novak motor and its golden. Literally. The EX motors break from Novaks traditional purple motor sleeve with a new gold one. And while the EX Brushless Motors may be described as “sport” models, they still include all of the great features of a Novak brushless motor 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.

A unique feature of all Novak motors is the ability to upgrade or replace various parts. Although deemed a sport model, the EX motors are no exception. Users are able to replace parts like the front end bell/bearing and rear bearing (#5905), as well as the rotor (#5906) if needed, and not simply toss the motor aside. Another option for the user is to upgrade the motor with a motor upgrade kit (#5923) for the pro performance of the SS-Series of motors.
