I just took another look for our friend briang(see other post). I carefully counted only two banks of 6 fets. They were placed in the same place as the 80A, but there were only 12 of them. I could not remove the heatsink - it was glued there, all visible chips were the KIA78D05F (looks like a regulator/power transistor) and a uC whose numbers were filed away. The layout was almost identical to the 80A (see briang's post) and the fan has 4 hex nuts which just screw (barely) into the heatsink..I got to find a way to keep the fan on.... The rubber seal also is useless because there is a hole there...I doubt it really can compete with the mmm, but I'll give it a try someday - it is my backup esc anyway.
