The Castle Sidewinder SV4 12.6V Waterproof 1/10 ESC builds upon Castle’s most popular platform, the Sidewinder 1/10 series. The ESC is the first of its kind to run Castle’s CRYO-DRIVE technology that combines technology from cutting-edge hardware and software advancements to increase thermal performance. Cooler temps mean longer runs and more power! The Sidewinder 4 is a versatile ESC and is a great choice for short course, on road  and monster truck applications when paired with the correct motor, as well as rock crawlers when used in brushed mode.

*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, Castle recommends 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.

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. Castle strongly suggests using 5,000mAh or larger LiPo cells with a discharge rating of at least 30C (or high quality 25C batteries). Castle suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.
  • Please refer to the Castle Gearing Chart for recommended motor, battery and gearing for some of the more popular vehicles on the market.

Castle Creations Sidewinder SW4 Waterproof 1/10 ESC
This is by far the best esc from castle. If you love the sidewinder, this is your baby. So smooth. Stays super cool, and there seems to be better power management. Under super light throttle where others (not sensored) would cog very bad, this has very minimal. It's just a great esc, and I recommend it to everyone that either races, or just simply beats the h*** put of it. I give this a 15/10

Castle Creations Sidewinder SW4 Waterproof 1/10 ESC
After only few times it started to not power on, friend of mine mentioned that its probably the switch, its a common thing for castle. Sometimes i have to turn it ON/OFF 4-5 times before it acctually turns on. Other than this it has been ok.
