We’re thrilled to introduce the Cobra 8, our next generation electronic speed controller (ESC) for surface applications. As the inaugural product in a new line, the Cobra 8 is engineered with cutting-edge technology tailored specifically for 1:8th scale vehicles weighing up to 15 lbs. The Cobra 8 boasts a state-of-the-art 32-bit, dual-core processor, ushering in a new era of precision and performance. Its enhanced data logging capabilities offer extended recording times, faster sampling rates, and a wealth of data points, enabling users to delve deeper into their vehicle’s performance than ever before. Crafted with a CNC aluminum bottom case, the Cobra 8 is engineered to endure the most rigorous conditions, ensuring reliability in every race or off-road adventure. One of its defining features is our acclaimed CRYO-DRIVET technology, engineered to reduce operational temperatures, significantly prolonging the ESC’s lifespan. Moreover, equipped with an impressive 8-amp BEC, the Cobra 8 can effortlessly power the most demanding servos, making it an indispensable ally in your high-performance setup. NEW FEATURES: 32-Bit Processing power for smoother motor control and improved response time. Enhanced Data Logging includes: Double the maximum sample frequency of older generations. 8x increased logging time of older generations. Data point for ESC electrical motor timing. Data point for acceleration via onboard accelerometer. Looping feature prevents interruptions in data log recording. Ability to download specific sessions. Additional tuning features include: Improved braking adjustability Separate brake and reverse curves Highly adjustable internal BEC. Now with USB-C connector! (Requires Windows 10 or higher) Mounting holes located in bottom of aluminum case for installation into vehicle. MORE FEATURES: Input Voltage Range 6.0v – 25.2v (2s – 6s LiPo) SmartSenseT, Sensored Only and Brushed Motor Operation Modes Powerful Integrated 8A Peak Adjustable BEC (5.00V – 8.0V) CRYO-DRIVET Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer Premium forged heatsink with elliptical fins for superior air flow and increased heat dissipation Oversized factory equipped thermally controlled 30mm cooling fan Waterproof design for all weather conditions Data logging capability to capture and record performance data from your vehicle Auxiliary wire functionality for “on-the-fly” adjustments using your transmitter Audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff Convenient transmitter programming for six common adjustable settings including cutoff voltage and drag brake Includes Castle Link V4 USB adapter for Windows. Technical Specs Controller Input Voltage Range. MIN: 2s LiPo MAX: 6s LiPo (25.2V) BEC Specifications. 5.0V – 8.0V adjustable in 0.1V increments; (8A Peak); default 5.5V Operating Environment.

Yes, factory equipped (30MM), temperature controlled Size. 60mm x 52mm x 43mm (2.36″ x 2.04″ x 1.69) Weight (with no battery connector). (165.6 grams) Connectors. 6.5mm female bullets for motor connection, matching 6.5mm male bullets included with motor. Items Needed for Operation. A high current connector designed for high-powered electric systems, rated for 120+ amps, such as Castle CC Bullet 6.5mm, CC Bullet 8.0mm, or 6.5mm Polarized Castle Connectors, soldered to the battery leads. Although the Cobra 8 ESC and Castle brushless motors are waterproof, they are not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC and motor with clean water after exposure to corrosives or dirt. While the motor and controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind. The cooling fan must be removed prior to driving in wet conditions. It is not waterproof. Ideal for 1:8 scale buggies, truggies, on-road vehicles and 1:10 scale monster trucks up to 15lbs. Not recommended for use in high speed 1/8th and larger applications (IE Arrma Infraction and Limitless, Traxxas XO-1) Programmability: Fully programmable Castle feature set using the included FREE Castle Link USB adapter and freely downloadable NEW Castle Link 2 WindowsT software. Castle Link Mobile App: Not compatible at this time. Telemetry Link Capable: Not compatible at this time. Motor Specs Input Voltage Range. Length: 75.4mm Diameter: 40mm (41.4mm with fins) Weight (w/wires). 426g (15.1oz) ; 380g without wires Shaft Size. Length: 20mm Diameter: 5mm Mounting Hole Specifications. 6.5mm male connectors on 10-gauge wire Application Guidelines: Ideal for 1:8 scale buggies, truggies, on-road vehicles and 1:10 scale monster trucks up to 15lbs. Not recommended for use in high speed 1/8th and larger applications (IE Arrma Infraction and Limitless, Traxxas XO-1) Tech Notes. Running modes: SMARTSENSET, Sensored, Sensorless with Castle sensored capable ESCs. Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments. We are an authorized dealer of every product we offer in our store.
