Sidewinder 4 Sensorless Waterproof ESC & 1412-3200kv Sensored Motor Combo (5mm Shaft)

Introduction

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.

What Makes a Great Motor?

You can push it harder, you can run it longer, and it stays cool under extreme loads. It also has the ability to withstand the harsh demands of any RC application, has a long-life and high-quality components, and has proven manufacturing techniques.

Efficiency Is Key

The higher the efficiency of a motor the more power it can produce without overheating, which allows you to safely run higher gear ratios. The higher the efficiency of a motor, the less power it takes to produce the same output power, which allows you to run longer on a single charge. The higher the efficiency of the motor, the less energy it turns into heat; keeping it cool under extreme loads. Efficiency equals performance.

Reliability Can't Be Ignored

Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it. Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. High-strength, high-temperature grade neodymium sintered magnets combined with a high-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. Castle's proprietary winding techniques allow them to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor. A cooler motor has a longer lifetime. Construction of the motor required careful component selection; each verified through internal testing to ensure the highest efficiency possible. In the end, the result is a motor with unmatched quality, performance, and reliability.

High Quality Design

Immense care is taken by Castle's US design team during every step of the development process. While using the highest quality components is important, design is equally important. Their experienced, in-house engineering team, located in Olathe, Kansas, has spent countless hours simulating and developing the most efficient design. Development includes magnetic simulations, custom winding techniques, and rigorous, real-world testing of the final product.

You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder.
