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 the 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 stealthily, 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. The Copperhead provides clean and constant power with its user selectable (through Castle Link) 5.5V or 7.5V (6A peak) internal BEC, eliminating concerns about brown-outs, glitching or slow actuating servos.

The ESC can be installed and calibrated (plug and play) for 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. You can also use the Castle Link Programming Suite on your Windows™ PC, or wirelessly with the B-Link™ Bluetooth™ Adapter and Castle Link app for Android or iOS. Additional Castle Link benefits include access to all firmware updates and added feature sets (at no charge), the ability to download and analyse your collected Data Log, an Intuitive Demo Mode capability, and the option to save setup profiles for multiple vehicles.

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 Copperhead logo simply clicks back into place on top of the ESC. The Copperhead also emits audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff, with a reference chart on the decal included in the box.

Pairing the Copperhead with a Castle 4-Pole 12-Slot sensored motor enables SmartSense™ 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.
