Let us take some of the stress out of holiday gift buying this season by giving you more time to qualify for price adjustments. Price adjustments on purchases are available 10/8/2022 until 12/25/22. If an item you buy has a price reduction before Christmas, we will credit the difference upon request, so you can shop confidently knowing your price is guaranteed.
All credits will be issued as Loyalty Club Points on your Tower Hobbies account.
The Hydra XLX2 is based on our popular and powerful Mamba XLX2 ESC. We've removed the air cooled heatsink and added a watercooled heatsink. It is finished off with an aluminum top plate for a clean look. Attached to the top plate are two aluminum, water fittings for 1/8" tubing and uses standard 10-32 UNF threads; package includes optional .17" fittings.
Castle’s proprietary breakthrough technology integrates unique software and dedicated hardware to reduce heat and dramatically increase performance. Thousands of times per second, the XLX2 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 for ultra-high performance.
You can easily optimize the ESC for any running conditions. Create, save and download setup profiles through the Castle Link Programming Suite on your 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 awaits you with on-the-fly adjustments from your transmitter via the Auxiliary wire. Simply connect the white signal wire to an open radio channel, and enable the feature in Castle Link by selecting what Auxiliary function you would like to use. Access programming parameters such as Torque Control, Max Brake or Max Throttle.
Due to the high power nature of the XLX2, you must use appropriately sized batteries and connectors. Castle recommends a minimum 150 amp connector for the Hydra XLX2; examples include Castle 6.5mm polarized, EC8 and QS8. DO NOT USE XT90, Traxxas, EC5/IC5 or any other connectors rated below 150 amps continuous.
