• Sensorless brushless and/or brushed motor operation.
• Waterproof design ESC and splash resistant 30MM fan*
• 5.0 volts fixed, 2 amps Peak BEC
• Audible alerts for error conditions
• Enhanced drag brake functionality
• Smoother sensorless startups
• Convenient transmitter programming for six common adjustable settings
• Additional settings and software updates available via Windows®-based Castle Link software and USB adapter (sold separately) or via Field Link Card  (sold separately) or via the Castle Link App and a B-LINK Bluetooth Adapter (sold separately).
• Telemetry Link  compatible for Futaba® S.BUS2 (sold separately)

 The SIDEWINDER 4 is a versatile ESC and is accepted in a wide variety of applications.  Whether throwing dirt, ripping through a corner or steadily dominating the trails, we’ve got you covered!

The Sidewinder 4 is available as:

• ESC only for rock crawling applications with brushed** motor down to 19 turn.
• ESC only for use with your existing Castle 1406, 1410 or 1415 4-Pole brushless motor
• ESC and motor combo packages, bundled with our 1406, 1410 and 1415 4-Pole brushless motors

*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.

Technical Specs
Controller
Input Voltage Range:	2s - 3s LiPo; 6 - 8 cell NiMH
BEC Specifications:	5.0 volts fixed, 2 amps.
Operating Environment:	Waterproof* design allows for use in nearly any environment
Brake:	Proportional
Reversible:	Yes, but may be disabled for racing.
On/Off Switch:	Yes
Cooling Fan:	30mm fan included
ESC Size:	L: 2.08" (52.92mm) W: 1.50" (38.05mm) H: 1.28" (32.56mm)
ESC Weight (w/wires):	2.26 oz. (64 g)
Connectors:	4mm female bullets for motor connection.
Items Needed for Operation:	Brushless or Brushed motor, Battery Connector required; Castle 4mm polarized connectors, Dean's Ultra Plug, or Traxxas Power Connector recommended.
Product Use Statements:	*Although Sidewinder 4 is waterproof, it is not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC with clean water after exposure to corrosives or dirt. While the controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind.
Application Guidelines:	The Sidewinder 4 is a versatile ESC that can be used in a wide variety of applications. it can be paired with any of our 14xx series 4-pole brushless motors; it can also be used in a rock crawling application with a brushed motor down to a 19 turn. Please refer to our Gearing Chart for recommended motor, battery and gearing for some of the more popular vehicles on the market.
Max. Recommended Vehicle Weight:	No more than 6.5lbs with battery, ready-to-run.
Programmability:	Fully programmable Castle feature set using Castle Link USB adapter(sold separately) and freely downloadable Castle Link Windows software, or the Castle Link App and a B-LINK Bluetooth Adapter (sold separately).
Telemetry Link Capable:	Yes
Tech Notes:	Not all LiPos are created equal, and surge ratings should never be used to determine a pack’s suitability for a brushless application. Use the CONTINUOUS C rating only. Brushless setups frequently hit 100+ amps in peaks. We strongly suggest using 5,000 mAh or larger LiPo cells with a discharge rating of at least 30C (or high quality 25C batteries such as Traxxas® Power Cells®). Our experience suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.

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.
