Custom ESCs?

[BrianG]

I've soldered the wires on the MMM with just a 60w Hakko iron. The trick is to use a clean and properly tinned large chisel tip as it has more "thermal storage". I then let it heat up for 5 minutes so it gets as hot as it's going to. Then, I add a little flux. After all that, it takes about 3-5 seconds to solder the wires. If it takes longer than that, I may warm up the whole ESC with a heat gun (on low) to around 100*F. This reduces the speed at which the soldering iron heat is whisked away.
