Hello sfstu,
I did see this briefly disscussed on RCTankwarfare and though the idea was great,but being tried in the wrong place to a degree. But figuring out the proper fuse and then using it between the board and the individual motor's would seem to be the best approach for they would blow hopefully before the board self disstructed.The problem is a fuse between the battery and the board and components will save a direct short in going to the battery (many things could happen in that situation)but will not protect any of the other functions connected with the board.A fuse in that particular configureation must in theory be heavy enough to be able to handle a total of all possible functions that can be run and could take place at the same time.There is nothing wrong therefore in a inline fuse being placed there of proper size,but this may still not save a board from a dirrect short or a stalled out motor.I think in line fuses between the board and each motor could very well save a board under several conditions for instance,(something blocking a track and stalling a motor,or a direct short in a motor).It may well be a very good idea other's would want to use if you can get it all worked out.
