The mosfet got so hot, it desoldered itself, moved on the surface mount pads, shorting them out, and blowing a few tracks.

Another fet has moved too, but the boards are soldered together, so I can't assess the damage properly.

Buy Cheap you get cheap....which sux for you because the company
may not replace the esc. But you might be able to send it in.
Might be better off buying a new esc thou...looks like a cheap chinease pos.
Not the real deal.

these are fantastic escs for the price.

but, if you see them rated as a 1:8 esc, 4s, and 100amp...

don't do all those things at once

1:8 off 3s is fine.
1:10 off 4s is fine.

I'd much rather buy a HobbyKing 100amp esc for a 1:10 and run 3s without issue than spend $150 on a Castle Creations Sidewinder and have it fail.

Nothing wrong with cheap escs, just know their limits.

Only way to find the limits, is to exceed them.

What brand is it?

I have that same esc, if something did happen to it I would have to say I have definitely gotten my $30 out of it already, and then some. I don't even think it has a "brand" as far as I know.

I am running it in a 1/8th buggy to sct conversion on 2s with a 4000kv chinese 8th scale motor.

To the OP, what were you running when it died?

Haaha!! Best description ever!! Get few more to spare, so you'll find out more of its limits. Try talk the factory into their authorize Trash Tester!!!

I have four in total.

I've run them off 4s in a Firestorm for speed runs without issue.

I've run them off 3s in a light weight 1:8 monster truck, without issue.

4s, and 1:8 however, is a bad idea.

they're excellent for the money, just don't push their limits.

Its a HobbyKing esc, sold under various names, not sure who they're made by.

3amp switchmode bec, good adjustment available with the programming card.

You know some parts are just week in electronics. Look at computers and cars. Some of the best parts just fail. chock it up as a bad part and try again.

I have that ESC in a 1/8 buggy. I haven't run it at the track yet, but I'll let everyone know how it does. I don't think 4s and 1/8 is a bad combo...that should be better than 3s and 1/8 since that would equate to more current (which means more heat and ultimate failures such as this). Just don't gear for 60mph in a 1/8 on 4s. In a MT, most ESCs are fine, even smaller, lower rated ones, because MTs have much higher (shorter) gearing, which helps with torque (and the sudden current spikes) required to get them started off the line. For the price, I've been satisfied at how well it runs. Not as smooth off the line as my Xeruns (it sort of suddenly kicks in and launches the buggy forward whereas the Xeruns go very smoothly, even sensorless), but it runs well and hasn't heated up with test speed runs up and down the street in 90F heat.

that isn't how it works, the 3s setup will draw considerable less current, assuming all things are equal (even gearing for the same top speed)

I'm now running a 120amp esc, and it appears to be too much for that too.

I have some new pinions on the way, but I find it strange that the motor doesn't heat up.
