Crawling has taken on a new dimension, and Novak is following its lead by introducing a pint-size counterpart to 1/10-scale crawling. Bred from the Goat Crawler Brushless System but sized the same as the Mongoose Micro Systems, Novak’s Mongoose Crawler Micro Brushless System – 18.5T is the first micro sensor-based system specifically designed for 1/18-scale crawler vehicles. The fully-programmable Mongoose Crawler System includes all of the features found in the Goat System, such as instant throttle response, super low-speed drivability and explosive torque, but also includes the ability to run on two or three-cell Li-Po batteries, which the speed control automatically detects through Novak’s auto detect software. Though the micro-sized system packs a lot of power, it fits perfectly in Losi’s® Mini Rock Crawler™, giving users the edge in crawling competitions.

The Mighty Mongoose
The Mongoose Crawler’s powerful 18.5-turn motor scales over other brushed motors because of its massive start up and low-speed torque. The 380-sized motor features a sensor-based commutation design to ensure no hesitation before acceleration, and provides smooth braking and controlled delivery of power. It provides longer run times than any stock crawler brushed motor and is as powerful as any dual crawler-micro brushed motor setup. Additionally, the brushless motor includes a high-strength sintered rotor with a rugged 1/8” shaft for stronger motor braking power and improved performance in higher temperature conditions. And like all Novak motors, it is completely rebuildable, allowing for the ability to upgrade or replace various motor parts.

Large Rocks, You Say? No Problem!
The Mongoose Crawler offers a plethora of crawling opportunities that are simply unavailable in stock crawler brushed systems. The micro crawler ESC comprises four throttle profiles to fine tune any crawler’s preference.

Linear Crawler — maintains standard motor response in forward/reverse, and features high-powered drag brakes.
Expo Crawler — features the standard crawler profile but uses a built-in exponential curve for smoother response.
Servo/Robotic Mode — features precise and symmetric motor control in forward and reverse for robot applications, but without the drag brake.
Brushed Mode — is automatically selected when used with a brushed motor.

The modifiable programming doesn’t end there. The micro crawler also includes a fully-programmable interface that can be adjusted with Novak’s easy One-Touch™ button and four-colored status LEDs. Moreover, Novak has also built into the ESC a Li-Po Cut-Off Circuitry feature, which prevents the batteries from going below the critical safety voltage level and can be activated in all four throttle profiles. For further crawling opportunities, the built-in motor rotation direction can be modified in any of the three brushless profiles; Zero Reverse Delay is available in all profiles for instant power delivery in both forward and reverse when needed; and adjustable hill/drag brakes are active in profiles one and two, which use battery power to slow the vehicle to a wheel-locking stop.

The Mongoose Crawler ESC has also been outfitted with a rugged 6 volt / 2 amp BEC to provide powerful and precise steering while embarking on unsteady landscape, with no additional BEC to purchase or install.

Novak Mongoose Micro Crawler Brushless ESC/Three-80 Brushless Crawler Motor Combo (18.5T)
Great little combo in my Mini Crawler Pro. I run the included pinion, 3oz of weight in each front tire, and 1.5oz in each rear tire and the motor barely gets warm to the touch. Low end torque is all that my crawler needs and the wheel speed was surprisingly more than I expected. Very small footprint on the esc made mounting very easy. Typical easy Novak programming.)
