The HYDRA X 8S is based on Castle's popular and powerful Mamba Monster X 8S. They've removed the air cooled heatsink and added a water-cooled heatsink. An aluminum top plate gives it a sleek and polished appearance. Attached to the top plate are two .17" aluminum water fittings using standard 10-32 UNF threads. The HYDRA X 8S is the ultimate ESC upgrade 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.

With its easy to dial in ESC settings you can update the ESC firmware and view data logs with a 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.
