Alrigh i almost had a fire in my lap yesterday and i have no idea why.

What i used;
Wp-1040-brushed esc,
Smc 7.4v 7200mah 60c 120b lipo battery,
Futaba T2PH 900mh tx/rx,
Colbalt 2 modified motor

What i did;
i plug in everything, i checked that everything was connected right because earlier that day i changed all endsnto traxxas so i made sure all wires lead to where they were suppose to. I turned it on and eased on the throttle.

End result;
Motor sparked like it should. Then a sizzling nosie followed by e loud pops and then the smoke poured out so thick andfast. I couldnt see anything anywhere. I reached for the batteru and couldnt find it the smoke was so thick and i was sitting right next to the back door whick i had fully opened. Finally i found the bagger and ripped it off and threw the esc out the door and checked quickly for signs of damage to the battery and it looks ok but its a hard case.

Questions;
What went wrong? Should the battery be ok? I have another wp-1040-brushed can i use it with the battery again as ive done 100 times before?

Looks like you maybe didn't have a jumper set correctly? Maybe a jumper jumping two separate pins? Battery should be okay, but measure the voltage with a voltmeter first to make sure nothing screwed up.

Tou cant really see them but both the pins were set closest to the wires on lipo and forward/reverse they always are i have o other batteries than lipos so i never move the pins. Plus i had used that battery/esc combo eaier that day testing a different motor but before soldering but i know the wires were bang on.

Oh. In that case, what might have happened is, you soldered the connectors to the wires on the ESC. Those wires carry that heat and you may have killed a component on that board, making it 100% passive (if possible) which friend a bunch of other stuff and then stopped at the VRM. I'd need to see a complete PCB to be sure.

Thats pssible. I thought i was quick enough doing it but i addmit i not the greatest at soldering and burn my finger holing a wire because it wouldnt go right. But the positive wire came right out after the esc blew up. But i had used that batteery/esc combo before testing out a different motor the only real differencw being i was using an adapter to go from the red banana plugs to a traxxas plug.

Now i have another wp-1040 that i soldered how can i check if its ok?

NOTE: the batter was/is the right way i checked and have been using it on my brushless since the esc problem.

Not sure how you can check. Did you hold the iron on the wire for too long? If so, that could have done it.

skygreen67

Possible. But how would you explain my use of it after i soldered it. It was soldered and used a couple days ago while the the battery was soldered that day and used since?

I'll bet that smelled good...

Ok guys please im begging for some advice... i just lost my second wp-1040 and could have been more... this time a new esc presoldered ddifferent controller different motor. And tbis time i tested the esc no motor and it was perfectly fine. I connect a motor and turn on the power and sizzle but this time i was sort of expecting it from when i tested with no motor and built in a kill swictch which i hit the second i heard the sizzle. What the heck is going on pleeease help mr.
