I think in the example, the bottom left LED should light up.  (All buttons and LED's are set to 'X')  It would allow us to activate an 'if' gate beyond a splitter to control a split-off drone part, effectively allowing us to segregate transmitted commands so that only those we need are transmitted. Furthermore, it just makes sense.  There's no reason for the wireless transmitter to act as a splitter - that's what we have splitters for. Signals transmitted from the core by the wireless part
