CRAWLING WITH PRECISION

Irvine, CA – June 18, 2007 – As the R/C crawling segment gains popularity, the need for crawler-specific equipment has become greater. Novak is happy to fill the need with a new Crawler Sintered Brushless Motor (#3419) and Crawler Sintered Brushless System (#3019). Novak has always felt that brushless technology is an ideal fit for crawling applications due to their instant throttle response, super low-speed drivability, and explosive torque —the very features crawling enthusiasts look for.

As any crawler aficionado can tell you, crawler vehicles require precise movement control at very low speeds. That being said, it makes sense to use equipment specifically designed for this purpose. Enter Novak Electronics. One of the few, if not the only R/C manufacturer, who offer electronic products specifically designed for crawlers. The new sensor-based Crawler Brushless Motor and System are equipped with features that enable crawlers to climb over, maneuver through, and conquer the most challenging terrain.

While the new Crawler Brushless Motor (#3419) and Crawler Brushless System look similar to the original #3418 Crawler Brushless Motor and #3018 Crawler Brushless System, there are several differences that greatly improve the performance.

The new Crawler Brushless ESC is now based on Novak’s XBR Sport ESC, which has been outfitted with crawler-specific software. It is equipped with an improved 6 volt/ 5 amp BEC that’s perfect for super high-torque servos in crawling conditions. Its Zero Reverse Delay allows instant power delivery in both forward and reverse when needed. Adjustable, high-power Drag Brakes, also known as “hold” or “hill” brakes, provide monster holding power that’s especially useful when embarking on a downhill descent. The Crawler ESC also has two throttle profiles: one with standard motor rotation, another with reverse motor rotation. In either profile, users can enable or disable built-in Li-Po cut-off protection, which monitors the vehicle’s Lithium Polymer battery pack’s voltage, and prevents the batteries from going below the critical safety voltage level.

The new Crawler Brushless Motor now includes 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

The new Crawler Brushless Motor still includes the same great features that have made it popular, including a larger, more rugged front bearing for extra durability and extended life (same bearing used in Novak’s Velociti-series motors). It still sports ribbed aluminum end bells, and the same popular solder tab system that is used in Novak’s Velociti-series motors. The lower-resistance solder tabs allow for more flexible soldering options, and are extremely efficient and easy to use. The solder tabs provide the lowest possible voltage drop, and allow for easy and convenient power wire replacement.

Along with the new Crawler Brushless ESC, which when used with will have optimum crawling performance, the Crawler Brushless Motor is also compatible with all Novak brushless ESCs, including the GTB-series (#1710, #1711, #1714, #1715), the XBR (#1720), and the Super Sport Plus (#1705) and original Super Sport ESC. The Crawler motor with any of these ESCs are an ideal setup for beginning drivers that are looking for slower speed and longer run times.

The Crawler Brushless System (#3019) includes one sensor-based, 18.5-turn Crawler Brushless Motor factory-wired to a new XBR-based Crawler Brushless ESC. The list price for the Crawler System is $339. The Crawler Motor will also be available individually as part #3419, and list price of $139. Shipping for the Crawler System and Motor is scheduled for end July 2007.
