Each esc has a sensor/controller section, and then the fets.CC use a separate controller on their hydra series esc, and on the 240 have 2 fet boards controlled by the one controller .
Noting that one fet board is the parent, the other a slave......
The controller card can be removed easily as it is a plugin module.
I am intrigued why the amp hungry have not attempted to mount 4x cc fet boards and use the one controller..all it may need is a firmware upgrade .. and a massive bank of input caps !
Sadly your suggestion to use to separate esc with outputs tied together just wont work.
Wayne, I think it has been done, I know a guy that used three boards stacked with one controller... this is as far as I can go telling you
about this since I cannot recall which controller with what boards. All I can say is, it's possible... not very practical since you'd need 2 ESC
to make one.
