This is the Novak Ballistic 540 SmCo Tuning Rotor. Novak has produced an incredible tuning option for the racing arena in their never-ending search to bring racers the absolute highest quality components and materials - the Samarium Cobalt (SmCo) Tuning Rotor. Developed to withstand extremely high temperatures, Novak designed this rotor to retain its core magnet strength over the course of a run so that your motor runs consistently, will not suffer from fade and will produce consistent braking and throttle response.

Using SmCo rare-earth materials, this rotor has higher demagnetizing ability than Neodymium, and will increase, and better sustain, RPM under load. This all translates to improved efficiency and added temperature tolerance─all crucial characteristics when you find yourself pushing the limits of racing. Recommended for all 540 applications.
