Castle Creations Sidewinder 4 Sensorless ESC & 1410 3800KV Brushless Motor Upgrade for 1/10 RC Vehicles SCT Edition, Black, Green

I have bought several of the sw4 esc love the fact you can get the Bluetooth programmer for it, I’ve never had any issues with castle it would be cool if they came in rc cars to start with they are the only thing I put in my rc

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.

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.

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.

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

Esc fried 2nd time out 2wd slash was not over geared or under....from now on will stay with hobby wing had to give castle a chance not impressed

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
