As more and more drivers head toward rugged terrain instead of the smooth track, the need for specialized crawler equipment has increased. Novak is pleased to be one of the few R/C manufactures that offer electronic products specifically designed for crawlers. Brushless technology is an ideal fit for crawling applications due to the instant throttle response, super low-speed drivability and explosive torque brushless products provide. The sensor-based Crawler Brushless Motors enable crawlers to climb over, maneuver through and conquer the most challenging terrain.
Additional features of Novak's Crawler Motors include sensor-based commutation for precise rotor position control; a high-performance sintered rotor for stronger motor braking power and improved performance in higher temperature conditions; an oversized front bearing for extra durability and extended life; ribbed aluminum end bells to reduce weight; and a solder tab system for flexible soldering options.
