This is what I was using. Is this a gun or an iron. I'm assuming iron.

I have a 30 watt cheapo special also. I'll give it a try I guess.
I was touching the iron directly to the solder on the bottom of the ESC so I should have had good heat transfer.
I did feel the body of the ESC get warm ( not hot ), so hopefully it's still OK.
