Overview
Introducing the Cobra 8, Castle's next generation electronic speed controller 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 6.8Kg (15 lbs).
Note: The Cobra 8 ESC is not intended for drag racing applications.
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 aluminium 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-DRIVE 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.

Cryo Drive
Castle's newest software technology, CRYO-DRIVE minimizes 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.
SmartSense
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. Once the motor is turning, it seamlessly transitions to Castle's ULTRA-EFFICIENT sensorless mode with electric timing. Smooth sensored startups and high-efficiency sensorless running makes the COBRA 8 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.
On-The-Fly Adjustment
The COBRA 8 allows on-the-fly adjustments to be made through the AUX wire once enabled in Castle Link. Once you have selected an AUX wire function, that setting can then be tuned from your transmitter while driving. Torque control, max throttle, max brake and drag brake adjustments are a sampling of the available modes. This real-time tuning allows you to quickly and easily fine-tune your system.
Data Logging
The COBRA 8 contains NEW DATA LOGGING FEATURES:
- 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.
You can view a detailed turn-by-turn record of what your ESC actually experienced during the run. You will be able to record real-time data such as motor RPM, battery current and voltage, ESC and motor temperature, throttle input, and more. Download and analyze the collected data via Castle Link and make adjustments to maximize both performance and battery life.
Castle Link
For over 25 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 download the BRAND NEW simple to install software from the Castle Creations website and you are ready to personalize your controller's settings. Requires Windows 10 or higher.
Waterproof
The COBRA 8 is housed in a rugged CNC-machined aluminium case and then potted in waterproof epoxy. This not only protects the electronics but ensures any heat generated in the controller can easily be dissipated through the case.
Alerts
COBRA 8 features Audible Alerts that will notify you, via audible chimes, of possible issues with calibrations and error conditions to help diagnose problems.

We want to ensure a smooth delivery experience for you, and here are some key details to keep in mind about our service.
- For orders exceeding £120, delivery is available exclusively to mainland UK addresses. However, orders below £120 can be delivered to outlying Isles and Northern Ireland, provided they meet specific criteria: they must be deliverable by Royal Mail, weigh less than 30kg, and fit within the dimensions of 61cm x 46cm x 46cm. Please be aware that certain highland areas may entail additional delivery fees, as couriers often charge more for these deliveries. If you reside in the highlands or any outlying regions, we recommend reaching out to us before placing your order to verify delivery options and any potential extra charges.
- Delivery is typically included in the price for the majority of our products, unless otherwise specified. However, please note that orders under £80 will incur an additional delivery charge. You can easily view this charge on the checkout page when finalising your purchase. We aim to maintain transparency in our pricing structure while providing you with the best possible service.
- Most orders will be delivered via either a next working day delivery service or within 2 working days, depending on your chosen service. Please note that for next working day delivery, the cut-off time is 12pm, and dispatch occurs exclusively on weekdays. However, certain items may have longer shipping times, and the expected delivery period will be clearly specified in the product listing.
- To streamline your order fulfillment process, please note that when your order includes items with varying shipping times, we follow this approach: If any item in your order has a longer shipping time, we will hold the entire order until all items are in stock. However, if certain items are expected to be restocked after a considerable delay, we offer you two options. You can choose to wait for complete fulfillment, where we'll dispatch the order once all items are back in stock. Alternatively, you have the option to receive a partial delivery, where we'll promptly send you the in-stock items and deliver the remaining items as they become available. Your satisfaction and convenience are paramount, and we strive to accommodate your preferences for multi-item orders.
- To ensure efficient delivery, we work with trusted carriers: DPD Local for next working day delivery and Royal Mail for the 2 working days option.
- After dispatching your goods, we'll promptly send you an email containing the parcel's tracking number. To ensure you stay updated conveniently, kindly provide a valid mobile number, which we will add to the consignment. This way, you can receive real-time updates on your mobile phone for added convenience.
- For listings specifying a shipping time of "Dispatched within 3 working days," please note that orders under this category will typically be delivered within a timeframe of 3 to 5 working days.
