The Crawler 540 Tuning Rotor – 14mm (#5950) was designed to alter the feel and experience of driving a Novak crawler motor, and offers a new dimension of tunability. With a larger diameter and improved magnetic material, the rotor provides more torque and stronger braking. It also increases natural drag braking and improves the motor’s initial throttle response, providing more control on steep climbs and downhill descents. The crawling sintered rotor is compatible with both of Novak’s SS18.5 (#3419) and SS21.5 (#3420) Pro Crawler Brushless Motors.
With its larger diameter, the new tuning rotor also cuts down the air gap in the motor, leading to more refined controllability.
