Novak Crawler Brushless Motor #3420**

As more and more drivers head toward rugged terrain instead of the smooth track, the need for specialized crawler equipment has increased. With this in mind, Novak has introduced two distinct Crawler motors: the #3419 Crawler 18.5 Sintered Brushless Motor and the #3420 Crawler 21.5 Brushless Motor.

Novak is pleased to be one of the few, if not the only R/C manufacturer, who offers 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.

CRAWLER 18.5 SINTERED BRUSHLESS MOTOR

The #3419 Sintered Crawler is the same motor included in Novak's #3019 Goat Crawler Brushless System. It is ideal for crawling applications as well as drivers looking for slower speeds and longer run times.

CRAWLER 21.5 BRUSHLESS MOTOR

Though Novak's 21.5 Brushless Crawler has many of the same great features as the updated #3419 Brushless Crawler 18.5 Sintered Motor, it has one key difference: It is even slower. With its lower-speed driveability and torque, the Crawler 21.5 Brushless Motor is equipped to tackle the harshest environments.

NOVAK CRAWLER FEATURES

The specially designed Crawler motors scale over other brushed motors because of their massive start up and low-speed torque, all without sacrificing power or control. This eliminates the need to use 3-cell Li-Po packs, required by out-runner motors, which adds unnecessary weight to the rig. Novak's lightweight brushless system can tackle the most challenging terrain on 2-cell Li-Po packs.

Both Crawler motors include the same high-performance sintered rotor that Novak’s Velociti-series motors currently use. The rotor is ideal for use with any and all applications, and provides the following benefits:

Significantly increased magnetic strength for improved throttle feel
Improved, stronger motor braking power
Improved performance in higher temperature conditions
Improved motor acceleration and power
Higher efficiency
Lower current draw
Nickel-plated for a long lasting, smooth, clean finish
Additional features of the Crawler 18.5 Sintered Brushless Motor and the Crawler 21.5 Brushless Motor 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.

The Crawler 21.5 Brushless Motor is specifically designed to work with Novak’s brushless crawler speed controls, including the new Goat Crawler Brushless/Brush ESC (#3219) and the original Novak Crawler Brushless ESC (in system #3018).

The Crawler 18.5 Sintered Brushless Motor and the Crawler 21.5 Brushless Motor are designed, hand-wound and dyno-tested by Novak experts.
