I have been running this setup for a few weeks now and esc sits around 37 deg c. Esc is clamped to heat sink and heat sink is sealed into board with silicone gasket.

Very interesting. Any chance for some more pictures? Batteries sit inside box? Is the board tail heavy? So many questions…

Batteries inside a cutout in the board with a sealed lid they sit over and infront of mast to balance everything out.
