4.12 cooling mod

Hello

While waiting on the A200S I decided to improve the heat capability on the 4.12 esc I'm using now.

I use it on a hub motor on a 20" rim @ 10s (3kW peak), so it's not surprising that I have problems with heat laugh 2-3 full throttle pulls and I was at the 80°C limit..

It's been below 70° on the ride I went for today up a "mountain". I didn't put any effort in making it look good since I'll (hopefully) get the A200S esc soon smiley

The copper pieces is slotted so both sides of mosfets get the same heat transfer. I see that this is not a mod for anyone, but it seems to work much better than I expected.
