Castle Creations 010-0164-00 Sidewinder 4 Waterproof Sensorless ESC

SIDEWINDER 4 is the first of its kind to run Castle’s newest technology: CRYO-DRIVE™ - A great example of what is possible when hardware and software harmoniously blend to maximize results!

On the software side, CRYO-DRIVE is a breakthrough that reduces the amount of time heat is being generated in internal components by optimally controlling which components are being used. This is happening thousands of times per second which greatly reduces the rate at which the Sidewinder 4 heats up.

On the hardware side, CRYO-DRIVE incorporates an all new redesigned case with a 44% larger and higher flowrate fan. The extreme ventilation of the new case design and bigger fan significantly increases the Sidewinder 4’s ability to remove heat from critical components, such as MOSFETs and capacitors.

With these advancements, CRYO-DRIVE takes thermal performance to a whole new level. This means you can expect MORE POWER, COOLER TEMPS and LONGER RUNS from the all new Sidewinder 4.

Whether you just need to upgrade your old ESC to get the most out of your current brushless/brushed motor, or you're in need of a full Castle brushless combo, your covered!
