One ESC getting hot, but controlling motor fine.

Got my quad flying the other day just great! Pretty stable!

Everything works great, EXCEPT, after the first flight, just ONE esc got extremely hot, while the others were relatively cool. I then unplugged the battery, it cooled down, then I plugged the battery back in. Without any throttle input, the ESC got hot again. Within 5 seconds.

I'm guessing this ESC gives power to the APM so is that why it's getting hot? I want to be sure before this thing lights on fire :-) I checked for incorrect solders, ect, nothing that I could see.

I want to be clear, that it powers the motor fine, it spins, and I got a good 15 minute flight out of it.

  • Yes its most likely the one powering the APM and electronics. It should be fine but alot of people get a seperate BEC connected to the main power input from the battery and disconnect the red wire on the esc.
