This is the Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC. Castle’s Sidewinder ESC is now waterproof! The Sidewinder 3 can power crawlers on water filled trails, AWD's in rain soaked parking lots, and SCT's on adventures through muddy fields. Drivers can now give in to those irresistible urges to drive in the mud or rip through puddles without damaging their ESC.

Designed for 1/10th
The Sidewinder 3 is a great fit for 1/10th off-road, on-road, and rock crawlers running up to 3S LiPo. It features updated circuitry for faster response time and improved reliability. As always, the Sidewinder 3 offers industry-leading software functions and USB programming capability via Castle Link USB adapter (sold separately).

Amazing Price
The Sidewinder 3 offers world class performance at an entry level price.

Legal mumbo jumbo
Although Sidewinder 3 and Castle brushless motors are waterproof, always rinse the ESC and motor with fresh water after exposure to corrosives or dirt. While the motor and controller may be waterproof, Castle suggests users confirm that the rest of their vehicle, including the batteries, servo, radio and chassis, are also waterproof before exposing them to liquids of any kind.

Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC
Very happy with my Sidewinder 3.
I like the 4mm motor plugs - allowed me to use short motor wires for a clean installation.
Love Castle Link. Created an expo throttle curve, custom drag brake and slightly reduced punch (torque) because I race on a medium traction track. It allows you to print the settings so you don't forget what you've changed and can use as a reference for future fine tuning.
I ran 20 laps with a 3800kv motor on 2 cells and the ESC was only at 120 degrees.(on a 92 degree day with the track surface at 135 degrees).
AND.......... Castle has a great warranty program. After your ESC is out of warranty, they offer discounted replacement as an out of warranty repair. GREAT CUSTOMER SERVICE.
Very happy with my Sidewinder 3.

I tend to be a critical consumer but I have to say, Castle Creations makes a great product, offers great customer service, has a great warranty and gives big discounts for out of warranty replacement.

Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC
best investment ever, this esc for the price is a bashers dream and i recently had a velenion esc and motor system.
the velenion esc's are junk and always have problems 2 of my have either fried or the button broke.
even i go to the track every now and then and it preforms greatly.
if you need a reliable great preforming esc at a extremely great price i would recommend this to every one but very serious racers to the point that it is not sensored

Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC
I have 5 of these ESC's in various basher RC's. They are absolutely rock solid on 2s when paired with Castle 1406 motors. Have had them for 10-ish years at this point, and they still work great. Super easy to program, fan shrouds are cheap and readily available, and they're priced extremely well.

It is not perfect, though. The BEC is weak, 5v 2a is enough to push low-torque and most 1/10 stock servos, like the Traxxas 2018 and 2056 series, but you may find its limit if you choose to upgrade. Whether that's a problem for you or not will depends entirely upon the vehicle and servo combo you want to run. For the on-road cars I have this ESC in, the built-in BEC more than sufficient. For my heavier 1/10 4x4 offroad and multi-servo trucks, I have added an external BEC so I could run servos with more grunt.

Anither small issue is the power switch. Its a double throw switch with one leg just bent over that sticks out the bottom of the housing. This lets water and other crud in, and over time can lead to corrosion building up in the switch. Can easily open the switch to clean it, but a bit annoying. I've run a few in some deep puddles, though, so not all the switch's fault.

Overall, and weak BEC aside, really have no complaints about this line of ESC. Super reliable, good package size, and puts out plenty of power.

Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC
Ok product. It only lasted about 5 or 6 runs before it suddenly stopped turning on. No beep, nothing and this is the second castle ESC to do this. After flipping the off/on switch repeatedly it will eventually turn on. another problem I have is now there is at least a 3 second delay between going into reverse from forward.

Update: 1 Year later it still is running. It does some of the things mentioned above occasionally. it's been in my Telluride and I've beaten the crap out of that vehicle and the esc still works. So i'm changing from 3 to 4 stars.

Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC
Experience with this has been horrible. First off the connections for the motor leads are top mount not side mount which means that you cannot put the body on your buggy if you mount the ESC on the ESC platform as it will be too tall. Secondly the receiver connection was so tight that I could not unplug it to use the castle link (one of the primary reasons I chose this ESC in the first place). Even with everything else unplugged I could not pull it out (old ESC does not have this problem). Eventually the plastic casing around the connector brok before the connectors would unclench. So Before it was ever even used it is broken.

I am so irritated that I wasted my money on this product.
