Product Overview
Meet the COPPERHEAD 10 PERFORMANCE ESC. It takes to the open road as well as it takes to no road at all. This completely new design rounds out our 1:10 scale offerings, positioned between the SIDEWINDER 4 as the entry-level upgrade and the MAMBA X as the extreme performance option. The COPPERHEAD 10 includes CRYO-DRIVE TECHNOLOGY, SENSORED MOTOR SUPPORT and DATA LOGGING LITE* with Castle's signature reliability and performance.
Throughout its development the Copperhead has been put to the test in all types of elements and performed as aggressively, or as stealthy, as desired. Whether on the trail dominating the gates or throwing dust on the dirt track, the Copperhead is power hungry when you need it and oozes smooth low-end power for technical low RPM performance. If your rig is outfitted with high-power servos (or additional torque increasing modifications) there is no need to worry about brown-outs, glitching or slow actuating servos. The Copperhead provides clean and constant power with its user selectable (through Castle Link) 5.5V or 7.5V (6A peak) internal BEC.
The ESC can be installed and calibrated (plug and play) and provide immediate fuss-free wheel time. Through the interface-free manual programming mode, using your transmitter you can set your low-voltage cutoff, brake/reverse type, brake amount, drag brake, motor type and direction. Likewise, you can employ the use of the Castle Link Programming Suite on your WindowsT PC, or wirelessly with the convenience of the new B-LinkT BluetoothT Adapter and Castle Link app for Android or iOS. Additional Castle Link benefits include access to all firmware updates and added features sets released from Castle Engineering (at no charge), the ability to download and analyze your collected Data Log , an Intuitive Demo Mode capability as well as the option to save setup profiles (for multiple vehicles) for later use.
For crawler setups or others that do not require an ESC cooling fan, the fan is easily removed with four screws and the fan guard with the cool COPPERHEAD logo simply clicks back into place on the top of the ESC. It keeps the COPPERHEAD 10 looking mean and provides an extra measure of protection. To further protect your investment, the COPPERHEAD emits audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff. You'll find a handy decal in your box that contains a reference chart for the eight alert tones, no need to Google while your enjoying your wheel time!
We've packaged the COPPERHEAD 10 with a dozen different 4-POLE 12-SLOT sensored motor options to eliminate the guesswork in finding the right brushless power upgrade for your basher, crawler, on road vehicle, short course or monster truck. An added bonus of pairing your Copperhead with a Castle 4-Pole 12-Slot sensored motor is enabling SMARTSENSET TECHNOLOGY, which uses the motor's sensors at startup to provide cog-free starts, excellent torque and low-speed drivability. Once the motor is turning, the ESC seamlessly transitions to Castle's ultra-efficient sensorless mode with electronic timing to advance timing automatically for peak performance in all driving conditions.
The all-new COPPERHEAD 10 PERFORMANCE 1:10 SCALE ESC is ideal for those who want sensored motor support, data logging, a 6A peak selectable internal BEC (5.5V or 7.5V) and Castle's signature reliability and performance in the meanest looking ESC around! If you're looking to transform your 1:10 scale stock vehicle from dull to dangerously fun COPPERHEAD can do it with its buttery smooth starts, CRYO-DRIVE enabled performance and up to 4S power in a compact, easy-to-install footprint.
*Data Logging capabilities require the use of Castle Link Programming Suite using a Windows PC and freely downloadable software.

Extended Features
Castle's newest software technology, CRYO-DRIVE minimises the amount of time the ESC's electrical components spend generating heat by optimally controlling which components are being used while driving the motor. This is happening thousands of times per second, which greatly reduces the rate at which the ESC heats up. This results in significantly improved thermal performance during partial throttle operation where the majority of driving occurs. Your setup will be able to handle higher gear ratios, in heavier vehicles, with longer runs.
When paired with a Castle 4-POLE 12-SLOT SENSORED MOTOR SmartSense software, enabled by default in the Castle Link Programming Suite, will use the motor's sensors to provide smooth starts, excellent torque, and low-speed drivability. Smooth sensored startups and high-efficiency sensorless running makes the COPPERHEAD 10 system produce more power and less heat. QUIETSENSE is an innovative advancement in the design of sensored motors to deliver the highest precision and most efficient startup.
Battery Voltage, Battery Ripple, Controller Temperature, Motor RPM and Motor Temperature data points can be captured, downloaded and analyzed via Castle Link software. While not a full version of Data Logging capabilities that the MAMBA X EXTREME 1:10 SCALE ESC has, these critical parameters are excellent sources of information for maximizing performance and battery life of the COPPERHEAD 10.
For over 20 years Castle engineers have been setting the bar for industry leading software functionality. The Castle Link Programming Suite is your ticket to creating the perfect setup. To gain access to the host of tuning parameters, simply use the Castle Link adapter with your Mamba XLX2 purchase and download the simple to install software from our website and you are ready to personalize your controller's settings.
