Your cart is empty.The SIDEWINDER 4 SCT EDITION COMBO includes a SIDEWINDER 4 ESC, featuring CRYO-DRIVE Technology, and a 1410-3800Kv brushless motor. This pairing is perfect for short course trucks running on 2s LiPo and weighing up to 6.5 lbs; it can be run on a 3s LiPo with very conservative gearing. It is a cooling running torque animal for lighter 1/10th scale 2WD stadium trucks and buggies running up to a 3s LiPo. Our 4-pole 12-slot motor designs boast exceptional efficiency, and the 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. You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder. SEND IT with a SIDEWINDER!

Everything about this is over powering for a 2wd slash. Extremely fun an durable the only issue is the fan starts acting funny if it gets wet. It starts to surge. Other then that i run 21p 86 spur doing 53 ish mph. on track is is just as good very durable doesn't over heat when ran modest on the track will last a full battery pack on 3s lipo no break needed. my first purchase with castle very satisfied been running strong for a yr now.

Great combo used in my traxxas slash 2wd sct. Highly reccomend getting the castle link ($20) so you can really fine tune. You can adjust just about anything you want on this ESC.

LOVE - the price and power driven. Took advantage of the link system and works wonders. In objective comparisons with traxxas velineon, I found neck to neck. The traxxas would overheat quite faster than the castle. I have yet to have had a run on a 3s 5500mah that had not overheated. 70 degree max runs so far

I installed this in a 2wd Traxxas Slash and it fit and works perfectly. I used the RPM esc cage to mount it which made the whole process much easier and cleaner. It also meant that I did not have to Dremel out a mounting point in the chassis and could use screws instead of double sided tape to mount the esc. It is a touch overpowered for the stock tires and I replaced those with ProLine Badlands tires, but if you like spinning around in little doughnuts making a lot of dust, you can leave the stock tires on.

Get a fan for the motor of your run 3s and you go to go. Castle does it again with this excellent combo. Need a soldering gun to add male esc connector to battery.

With the respect that castle has in the rc community, I was expecting better from them as this was my first purchase from their line up but I have had problems with the esc from the rip. The fam is sporadic in operation making squealing noises and stopping and restarting. Never really getting to a full speed and maintaining. The on off switch only worked a few times before it became a nightmare to switch on so that it would stay on. As I see it , both fan and on/off switches are a new thing for castle .. my suggestion is to find better fans and switches. Other than these 2 issues I think all is fine. I replaced the fan myself and bypassed the switch until a new one arrives. I paid for fan and switch out of my own pocket. Castle, if your listening, wouldn't hurt my feeling if you reached out to me and gave a little support. I'm sure it's "covid crap" related but I have had no luck reaching anyone by phone. I sure would like to make contact as well as give a better review. I was saving for a mamba set but opted to try the sw4 but really wish I had waited. Thanks be safe and enjoy your rc hobby
