While the all new SIDEWINDER 4™ builds upon Castle’s most popular platform, the SIDEWINDER 1/10 SCALE SERIES, it is the first of its kind to run Castle’s newest technology, CRYO-DRIVE™.  CRYO-DRIVE™ combines technology from cutting-edge hardware and software advancements to increase thermal performance.  COOLER TEMPS mean LONGER RUNS and MORE POWER in your SIDEWINDER 4 setup. 

Now with Cryo-Drive!Cryo-Drive technology is the result of Castle Creations' software and electrical engineers putting their heads together to improve the thermal performance of the well-known Sidewinder 3 electronic speed control.  Castle has developed new software that 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 Sidewinder 4 heats up.  Overall, the Sidewinder 4 generates heat much slower than previous versions. 

This software breakthrough has been coupled with a completely re-designed case.  A great deal of time was spent studying fluid dynamics simulations in order to optimize the airflow through the case.  Improving the airflow into and out of the case, allows the cooling fan to become more effective.  In order to take full advantage of the improved airflow efficiencies, a 44% larger, higher flowrate 30mm fan was selected.  The improved case coupled with the 30mm fan significantly increases the Sidewinder 4's ability to remove heat from critical components, such as MOSFETs and capacitors. 

By reducing the rate at which the Sidewinder 4 heats up and removing heat more efficiently, Cryo-Drive takes thermal performance to a whole new level.  The Sidewinder 4 allows users to push beyond the limits of previous generation Sidewinders by handling higher gear ratios in heavier vehicles with longer runs. 

*Not intended for operation while submerged in liquid.  If unit is operated in wet conditions, rinse with fresh water to remove dirt or corrosives, then fully dry unit. 

**Brushed motors are recommended for rock crawlers (vehicles traveling 3-5mph.)  Brushless motors are fine for use with rock racing.  If your vehicle is going to be in a bound up situation, very slowly traversing rocks and obstacles, you are running a rock crawler.  If you are constantly traveling at 5mph or higher, you have a rock racer.
