Thanks Steve. I'm planning to build a single board ESC with Joe's PIC and the h-bridge based on the OSMC. It should do 80A continuous at 24V. This brings the costs of the board to a lower level. An estimated cost of less then 100$. One board design is also more robust and better fitting in a tank hull.
