Are you ready for a Sidewinder Grin?

Finally, affordable brushless power for the people! Castle’s new Sidewinder brushless ESC series slashes the brushless price barrier while it blasts across the track in all 1/10th scale applications. Sidewinder is a great first high-performance package; it will provide more power and grins than most guys (and cars) can handle!

Castle’s engineers have achieved breakthroughs in circuit board thermal design and have combined those advances with cutting edge electronic components to bring unmatched power and reliability to sport 1/10th scale vehicle drivers. Castle’s leadership in this field allows us to drive the component pricing to unprecedented levels which means that we can pass the savings on to our drivers. Brushless power and reliability have never been available at these price levels!

Fully Functional - Yet Easy to Use

The Sidewinder ESC is ready to run out of the box, but it is completely Castle Link™ compatible too – drivers can use their Castle Link and Windows PC to tune and tweak all their favorite settings such as brake and throttle curves, throttle response, drag brake and many other parameters that add up to an incredible RC driving experience.

The Sidewinder 1/10th scale ESC is intended for use with the Castle 4600 KV motor up to 3S (12 Cell NiMH) and the long time favorite Castle 5700 with 2S Lipo (8 cell NiMH) MAX. Castle’s incredible CM-36 4600 kV and 5700 kV motors are made to exacting specifications and offer some of the best electromagnetic efficiencies of any motors on the RC market. We know, we’ve dyno’ed the rest and we feel we’re the best! Castle motors simply run cooler for a given power level – that means you can run them at higher power levels without worrying about thermal damage. Our top quality Neodymium magnets, carefully designed windings and high RPM bearings deliver an incredible punch.

Runs Brushed Too!

Use all the power handling and custom tweaking of the Sidewinder with your brushed motors too. That’s right, Sidewinder is easily configured to run conventional brushed motors for those who may need to run brushed to compete in some racing classes. One controller can provide the solution you need!

Why Two Motor Choices?

Sidewinder is available with our 4600 kV* and our 5700 kV* motors. Drivers can mix and match gearing and the number of cells that they are using to create a power system that can be mild or a raging wild thing with either motor. Both motors will make the cars go insanely fast; the 4600 will generally result in a more driveable car with finesse on throttle; the 5700 is more like a big block in a 60’s muscle car.

*The term kV refers to the number of RPMs that the motors will try to deliver per volt applied.

Does Sidewinder replace Mamba Max?

No, the Sidewinder series is designed for sport customers. Hard core racers will still demand Mamba Max power, just like the national champion drivers do. Sidewinder is an exciting entry point for high performance brushless offering approximately 2/3rds of the extreme power available with Castle’s Mamba systems.
