Well, it would take a little work. I found that when I removed the heatshrink, that the brains board is just held on with a special connector (no soldering). So, it's just held on via heatshrink. Makes removal easy (the FET boards have this same connector, but also have soldered heavy power and motor bridges). Figuring out the pinout shouldn't be too hard either (GriffinRU, are you listening?
). There are a few other things to work out (like gate drive, using the Opto instead of a BEC, etc), but a worthwhile goal IMO...
