ROOSTER CRAWLER EDITION
Irvine, CA – June 18, 2007 – Attention crawler enthusiasts — great news! One of Novak’s most popular brushed ESCs, the Rooster, is now available in a Crawler edition. Because crawler vehicles require such precise movement control at low speeds, it only makes sense to use equipment specifically designed for this purpose. Novak is one of the few, if not the only R/C manufacturer, who offers a speed control specifically designed for crawlers. So if crawling is what you like to do, you’ll want to take a good look at Novak’s Rooster Crawler-Edition.

Besides a different case label, the Rooster Crawler looks the same as the Rooster 12T. Same small footprint, same heat sink assembly, and same 14-gauge power wires on PCB-direct solder tabs for easy soldering. Inside the orange case, however, is where crawler-specific software transforms the Rooster into a Crawler. The special software enables crawler applications to scale, navigate, and conquer the most challenging terrain.

The Rooster Crawler 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. High-power Drag Brakes provide monster holding power that’s especially useful when embarking on a downhill descent. And yes, the Rooster Crawler edition includes the newest must-have feature: built-in Li-Po cut-off protection. This feature monitors the vehicle’s Lithium Polymer battery pack’s voltage, and prevents the batteries from going below the critical safety voltage level. The driver is cued via throttle blips when the voltage drops to a certain level. After 20 blips it then shuts off, however, full control of the steering servo is left intact. The Li-Po cut-off protection feature can be enabled or disabled via the ESC’s two throttle profiles.

Other Rooster Crawler features include a water-resistant case, a user-replaceable input harness, and auxiliary fan connectors. Of course, all the standard features for which Novak is known are also included: One-Touch Set-Up™, Radio-Priority Circuitry™, Polar Drive Circuitry™, and Thermal Overload Protection.

The Rooster Crawler is compatible with single and dual brushed motor crawler applications such as a single Mabuchi 27-turn motor or dual 35 to 55-turn lathe motors.

The #1841 Rooster Crawler-Edition Brushed ESC will be available End June 2007. The retail price
is $149.

Wow, another sign that the crawler scene is definately heating up.

its cool to see Novak trying to set up to the plate and offer a decent crawler ESC. one thing i noticed:

"Motor Limit 27-turn brushed (at 6 cells Ni-MH)"

this means on a clod buster you have to run at least (2) 55t motors and nothing less? with all the other high end specs im curious to see if this is a mistake or if you really need such a high wind motor. i know some guys like to run (2) 35 turn motors or even (2) 45t motors which in essence would be like running a 17.5t and 22.5 motor respectfully.

This looks nice! As long as its priced around $80 or so it will be worth it. Anything higher and Id rather just go with a Mamba Max esc. I wouldn't mind testing one of these in my clod supers. Im wondering how the BEC would handle both 55 turn motors and two Hitec 5995TG servos. Other than that this would be nice in my 2.2.

Hrm, I would pick up one of these if the price is right. I have one of the newer Rooster 12T ESC and love it.

"The Rooster Crawler is compatible with single and dual brushed motor crawler applications such as a single Mabuchi 27-turn motor or dual 35 to 55-turn lathe motors."

thats awesome, thank you.

Street prices on new products are generally high until the items start shipping---the Rooster Crawler prices are already under $90.00.

By the way, EVX prices were established by Traxxas, not Novak.

The EVX is only $114 at my store.

Nice! I already have a Rooster 12T in my current crawler, but I really could use the improved drag brake option. That, plus the instantaneous reverse should give me far better control, especially on descents. Thank you Novak!
