0-NOV3421 Novac SS 21.5 Pro Brushless Motor <p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Novak's award-winning SS Pro Brushless Motor offers a world-class spec-racing experience. It is equipped with a nickel-plated sintered neodymium rotor for maximum motor acceleration, braking power and performance in high-temperature conditions, and thermal overload technology to ensure the motor is operating at a safe temperature. The SS Pro motor also features a shielded-sensor cable and a completely rebuildable design, allowing for the ability to upgrade or replace various motor parts.</font></p>

Of its many features, the SS Pro's sensor-based design allows for most of the motors' important benefits.<br>
No Cogging--Thanks to constantly knowing the rotor position, the motor provides instantaneous throttle response and smooth transitions from neutral to drive. The rotor position knowledge is attained due to the ESC and motor being continuously synchronized via the motor harness.<br>
Smooth and Controlled Low Speed Driveability--Always knowing the rotor angle is key to smooth acceleration without delivering abrupt and uncontrolled bursts of power.<br>
Strong/Consistent Brakes and Starting Torque--Rotor position knowledge results in consistent starts and stops, without hesitation or inconsistent lag times before acceleration or braking--this translates to consistant lap times.<br>
Thermal Protection--Temperature sensors inside motor provide unparalleled thermal protection, allowing you to run pack after pack without worrying about overheating the motor, ESC or magnets. </font></p>
