p.s. I was looking at your esc cooling, wouldnt cooling be greatly improved by wrapping the esc with a plate of aluminum, like a strap. I would think it would give it greater heat transfer. I dont mean a water jacket, but just a strap that connect on either end to your existing cooling plate. Reason I was thinking this, is since the esc is stacked, I would think only the bottom circuit board is really getting the full benefit of the water cooling.
