couldn't this "esc" be used? putting the " " here because it is different to the ones we're used to, but doing the same job... only the input signal is different. But maybe there is a workaround for that?
Maybe flash new software on them, or adding a small extern chip to convert that signal (would think that could be as small as the transceivers are).
Software and electronics is really not my strong side, so just throwing in some ideas and hope you guys could pick one out that could work, but possibly nobody else did think of before
