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 the new Goat Crawler Brushless System (#3019), Goat Crawler Brushless/Brush ESC (#3219), and Crawler Sintered Brushless Motor (#3419).
The following four driving profiles make the Goat a versatile speed control:
* Standard Crawler — maintains crawler motor response in both forward and reverse and features high-powered drag brakes.
* Expo Crawler — features the standard crawler profile but uses a built-in exponential curve for smoother response to accommodate entry-level transmitters.
* 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. For use with brushed motors down to 27-turns.
GOAT CRAWLER BRUSHLESS/BRUSH ESC FEATURES
Four user-selectable brushless throttle profiles that feature Zero Reverse Delay and full programmability:
* Standard Crawler: maintains standard throttle response in forward and reverse
* Expo Crawler: Standard Crawler profile featuring a smoother exponential throttle response
* Servo/Robotic Mode: delivers symmetrical motor control for robot applications
* Brushed Mode: an automatically selected brushed-motor mode
- Fully programmable interface using the Novak One-Touch button to adjust Minimum Drive, Deadband, and high-power Hill/Drag Brakes (except Servo/Robotic Mode). Drive Frequency is adjustable in the Brushed Mode
- Built-in Li-Poly Cutoff Protection which prevents Li-Po battery damage (can be activated in all profiles)
- Built-in Motor Rotation Software (can be activated in brushless modes only)
- Built-in power 6V output for optional accessory fan (Novak #5648), or other detail items
- Gold-Plated PCB Direct-Solder Wiring Tabs for flexible soldering options
- Water-resistant case
- Factory-installed power capacitor (Novak #5682)
- User-replaceable input harness (Novak #5320)
