HYDRA X 8S, 33.6V ESC, 8A PEAK BEC

Product #: 010-0175-00

Introducing the newest addition to the world of RC hobby boats, the HYDRA X 8S. With its sleek design and powerful performance, it will push RC boats to their limits for the ultimate thrill ride on the water!

The HYDRA X 8S is based on our popular and powerful Mamba Monster X 8S. We've removed the air cooled heatsink and added a water-cooled heatsink. The final touch is an aluminum top plate that gives it a sleek and polished appearance. Attached to the top plate are two .17" aluminum water fittings and uses standard 10-32 UNF threads.  The HYDRA X 8S is the ultimate enhancement that propels high-performance monohulls, up to 36 inches in length, to new heights.

CRYO-DRIVE™, Castle’s proprietary breakthrough technology, integrates unique software to reduce heat and dramatically increase performance.  Thousands of times per second, the Hydra X 8S software minimizes the amount of time the electrical components spend generating heat.  The results are more power handling, cooler ESC temperatures and longer runtimes and ultra-high performance.

It's easy to dial in ESC settings, update ESC firmware and view data logs with Castle Link USB programming kit (coupon for USB adapter included with purchase) and a Windows™ PC, or wirelessly with the convenience of the new B-Link™ Bluetooth™ Adapter and Castle Link app for Android or iOS.  Additional tuning flexibility is available with on-the-fly adjustments from a compatible transmitter via the Auxiliary wire. It's as easy as connecting the white signal wire to an open radio channel and enabling the feature in Castle Link by selecting what Auxiliary function is preferred.

Castle Creations, Inc. warrants this product to be free from manufacturing defects for a period of one year from date of purchase.

This is a high power product with the potential to be very dangerous. Please read the safety information before use. This product may contain chemicals known to the State of California to cause cancer and or birth defects or other reproductive harm.

*RC HOBBY CURRENT RATING: Castle does not generally publish amperage ratings for surface ESCs. There is no standardized industry method for testing and rating ESC current capabilities. Castle's testing methods tend to result in much lower numbers than our competitors; we feel our numbers better represent the products actual capabilities. But due to the difference in testing and rating methods, our ESCs can look weaker in comparison to our competition. Please keep that in mind.

The continuous current rating is for 5 minutes with proper cooling, adequate connectors, and batteries. Using improperly sized components can lead to ESC stress and failure that is not covered by the warranty. Controller temperature must never exceed 100° C (212° F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load to decrease the ESC's operating temperature. Many users have pushed MUCH higher numbers, but Castle makes no guarantees on the long term reliability of the product or on the warranty.

The burst rating is for short, momentary periods lasting no more than 2 seconds. The time between bursts, how long the burst lasts, and water temperature will affect temperatures. Make sure all components in the system (battery, connectors, motor) are capable of handling said current. Closely monitor ESC, motor and battery temperatures and review ESC's data logs.

U.S. Patent # 7400103, 7492122, 7579796, 7740516, 8287328, 8678875, and 8905814 B2 - Other patents pending.

Product Features
  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.

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 Hydra XLX2 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.

The Hydra XLX2 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. . Click here for additional information.

Enabled by default, the Hydra XLX2 captures and records performance data from your vehicle. This allows you to 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.


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 redeem the coupon for the Castle Link adapter included with your Hydra XLX2 purchase and download the simple to install software from our website and you are ready to personalize your controller's settings. You can now wirelessly program your ESC with the free Castle Link Mobile App and the purchase the B-Link Bluetooth Adapter. Click here for settings overview for the Hydra X 8S. 

You can now WIRELESSLY PROGRAM settings with the free Castle-Link app available on the Apple App store or Google Play for Android devices and the Castle B-Link™ Bluetooth™ Adapter (sold separately). It is compact and lightweight installed in your vehicle, for anytime programming!



Hydra X 8S is telemetry ready, which means owners of Futaba 4PX, 7PX, 7PXR, and T10PX transmitters will be able to purchase the Castle Creations Telemetry Link for S.BUS2. Real-time data such as ESC temperature, voltages, and RPM can be monitored to ensure performance advantages and spare you the “unknown” parameters that all R/C enthusiasts experience at some point. Telemetry data provides another level of protection and can increase performance.

Housed in a rugged CNC-machined aluminum 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.

Hydra X 8S features Audible Alerts that will notify you via audible chimes of possible issues with calibrations and error conditions to help diagnose problems .

The Hydra X 8S is proudly designed and manufactured in Olathe, Kansas USA and is backed by Castle Creations’ 1-year warranty and unparalleled "make-it-right" customer support.
